• Can AutoIt scripts run as a scheduled task while not logged in?

  - by muddywater

  I am using Ruby/WATIR/AutoIt to automate a task via Task Scheduler which runs fine as long as I am logged in, but as soon as my account is locked (mandated 10 minute screen lock) or I logout the script stops functioning. When I log back in, it is sitting at the part where AutoIt is supposed to handle a file download dialogue by clicking save and then entering the filename and clicking to save again. The follwing is the code that works while I am logged in. Is AutoIt supposed to work when I am not logged in, and is there some other way to accomplish this? Thanks!! because search has not turned up anything (terms are too generic) prompt_message = "Do you want to save this file, or find a program online to open it?" window_title = "File Download" save_dialog = WIN32OLE.new("AutoItX3.Control") sleep 1 save_dialog_obtained = save_dialog.WinWaitActive(window_title,prompt_message, 25) save_dialog.ControlFocus(window_title, prompt_message, "&Save") sleep 1 save_dialog.Send("S") save_dialog.ControlClick(window_title, prompt_message, "&Save") save_dialog.WinSetTitle(window_title, prompt_message, "This is ForTesting" ) saveas_dialog_obtained = save_dialog.WinWait("Save As", "Save&in", 5) sleep 1 path = fileName puts " Edit the file path" save_dialog.ControlSend("Save As", "", "Edit1",path) sleep 4 puts " Save the file" save_dialog.ControlClick("Save As", "Save &in", "&Save") save_fileAlreadyExists = save_dialog.Send("Y")

• CreateProcess doesn't pass command line arguments

  - by mnh

  Hello I have the following code but it isn't working as expected, can't figure out what the problem is. Basically, I'm executing a process (a .NET process) and passing it command line arguments, it is executed successfully by CreateProcess() but CreateProcess() isn't passing the command line arguments What am I doing wrong here?? int main(int argc, char* argv[]) { PROCESS_INFORMATION ProcessInfo; //This is what we get as an [out] parameter STARTUPINFO StartupInfo; //This is an [in] parameter ZeroMemory(&StartupInfo, sizeof(StartupInfo)); StartupInfo.cb = sizeof StartupInfo ; //Only compulsory field LPTSTR cmdArgs = "[email protected]"; if(CreateProcess("D:\\email\\smtp.exe", cmdArgs, NULL,NULL,FALSE,0,NULL, NULL,&StartupInfo,&ProcessInfo)) { WaitForSingleObject(ProcessInfo.hProcess,INFINITE); CloseHandle(ProcessInfo.hThread); CloseHandle(ProcessInfo.hProcess); printf("Yohoo!"); } else { printf("The process could not be started..."); } return 0; } EDIT: Hey one more thing, if I pass my cmdArgs like this: // a space as the first character LPTSTR cmdArgs = " [email protected]"; Then I get the error, then CreateProcess returns TRUE but my target process isn't executed. Object reference not set to an instance of an object

• Extract a subset of XML file using XSL

  - by Lucas -luky- Noleto

  I have this XML file: <Response> <errorCode>error Code</errorCode> <errorMessage>msg</errorMessage> <ResponseParameters> <className> <attribute1>a</attribute1> <attribute2>b</attribute2> </className> </ResponseParameters> </Response> And I want the output to be: <className> <attribute1>a</attribute1> <attribute2>b</attribute2> </className> My current XSL file is including also "ResponseParameters" tag, which I do not want. EDIT: note that the node className is dynamic. I do not know what will be this name at runtime. <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:output indent="yes" /> <xsl:template match="/"> <xsl:copy-of select="//ResponseParameters"> </xsl:copy-of> </xsl:template> </xsl:stylesheet>

• WPF DataGridTemplateColumn. Am I missing something?

  - by plotnick

  <data:DataGridTemplateColumn Header="Name"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Name}"> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> <data:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <TextBox Text="{Binding Name}"> </DataTemplate> </data:DataGridTemplateColumn.CellEditingTemplate> </data:DataGridTemplateColumn> It's clear example of Template column, right? What could be wrong with that? So, here is the thing - when a user navigates through DataGrid with hitting TAB-key, it needs to hit the TAB twice(!) to be able to edit text in TextBox. How could I make it editable as soon as the user gets the column focus, I mean even if he just starts typing? Ok. I found a way - into Grid.KeyUp() I put the code below: if (Grid.CurrentColumn.Header.ToString() == "UserName") { if (e.Key != Key.Escape) { Grid.BeginEdit(); // Simply send another TAB press if (Keyboard.FocusedElement is Microsoft.Windows.Controls.DataGridCell) { var keyEvt = new KeyEventArgs(Keyboard.PrimaryDevice, Keyboard.PrimaryDevice.ActiveSource, 0, Key.Tab) { RoutedEvent = Keyboard.KeyDownEvent }; InputManager.Current.ProcessInput(keyEvt); } } }

• How to Global onRouteRequest directly to onBadRequest?

  - by virtualeyes

  EDIT Came up with this to sanitize URI date params prior to passing off to Play router val ymdMatcher = "\\d{8}".r // matcher for yyyyMMdd URI param val ymdFormat = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd") def ymd2Date(ymd: String) = ymdFormat.parseDateTime(ymd) override def onRouteRequest(r: RequestHeader): Option[Handler] = { import play.api.i18n.Messages ymdMatcher.findFirstIn(r.uri) map{ ymd=> try { ymd2Date( ymd); super.onRouteRequest(r) } catch { case e:Exception => // kick to "bad" action handler on invalid date Some(controllers.Application.bad(Messages("bad.date.format"))) } } getOrElse(super.onRouteRequest(r)) } ORIGINAL Let's say I want to return a BadRequest result type for all /foo URIs: override def onBadRequest(r: RequestHeader, error: String) = { BadRequest("Bad Request: " + error) } override def onRouteRequest(r: RequestHeader): Option[Handler] = { if(r.uri.startsWith("/foo") onBadRequest("go away") else super.onRouteRequest(r) } Of course does not work, since the expected return type is Option[play.api.mvc.Handler] What's the idiomatic way to deal with this, create a default Application controller method to handle filtered bad requests? Ideally, since I know in onRouteRequest that /foo is in fact a BadRequest, I'd like to call onBadRequest directly. Should note that this is a contrived example, am actually verifying a URI yyyyMMdd date param, and BadRequest-ing if it does not parse to a JodaTime instance -- basically a catch-all filter to sanitize a given date param rather than handling on every single controller method call, not to mention, avoiding cluttering up application log with useless stack traces re: invalid date parse conversions (have several MBs of these junk trace entries accruing daily due to users pointlessly manipulating the uri date in attempts to get at paid subscriber content)

• Entity Framework & Binding syncronisation

  - by Jefim

  * EDIT * Sorry, I should make it clearer. Imagine I have an entity: public class MyObject { public string Name { get; set; } } And I have a ListBox: <ListBox x:Name="lbParts"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding Name}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> I bind it to a collection in code-behind: ObjectQuery<MyObject> componentQuery = context.MyObjectSet; Binding b = new Binding(); b.Source = componentQuery; lbParts.SetBinding(ListBox.ItemsSourceProperty, b); And the on a button click I add an entity to the MyObjectSet: var myObject = new MyObject { Name = "Test" }; context.AddToMyObjectSet(myObject); Here is the problem - this object needs to update in the UI to. But it is not added there :( Help!

• SQL Syntax to count unique users completing a task

  - by Belliez

  I have the following code which shows me what users has completed ticket and this lists each user and the date they close a ticket. i.e. Paul Matt Matt Bob Matt Paul Matt Matt At the moment I manually count each user myself to see their totals for the day. EDIT: Changed output as columns instead of rows: What I have been trying to do is get SQL Server to do this for me i.e. the final result to look like: Paul | 2 Matt | 5 Bob | 1 My code I am currently using is and I would be greatful if someone can help me change this so I can get it outputting something similar to above?

• IIS 6 with wildcard mapping and UNC virtual directory problem

  - by El Che

  Hi. On our production servers (win 2003 with IIS6 and load balanced with an F5 BIGIP), we have a problem when introducing wildcardmapping on IIS6. We use .net Framework 3.5 SP1. The issue manifests itself as by the server only sometimes serving the images stored on a virtual directory pointing to a UNC path. Sometimes the images are displayed, and sometimes not. Removing the wildcard mapping solved this problem. I will need wildcard mapping on the server for future features, so any help/pointers to if this is a known problem will be very helpful. In advance, thanks for any help. Edit: The exception it fails with is the following: Message: Failed to start monitoring changes to '\ourFileServer\folder1\thumbnails' because the network BIOS command limit has been reached. For more information on this error, please refer to Microsoft knowledge base article 810886. Hosting on a UNC share is not supported for the Windows XP Platform.

• Mapping interface or abstract class component

  - by Yann Trevin

  Please consider the following simple use case: public class Foo { public virtual int Id { get; protected set; } public virtual IBar Bar { get; set; } } public interface IBar { string Text { get; set; } } public class Bar : IBar { public virtual string Text { get; set; } } And the fluent-nhibernate map class: public class FooMap : ClassMap<Foo> { public FooMap() { Id(x => x.Id); Component(x => x.Bar, m => { m.Map(x => x.Text); }); } } While running any query with configuration, I get the following exception: NHibernate.InstantiationException: "Cannot instantiate abstract class or interface: NHMappingTest.IBar" It seems that NHibernate tries to instantiate an IBar object instead of the Bar concrete class. How to let Fluent-NHibernate know which concrete class to instantiate when the property returns an interface or an abstract base class? EDIT: Explicitly specify the type of component by writing Component<Bar> (as suggested by Sly) has no effect and causes the same exception to occur. EDIT2: Thanks to vedklyv and Paul Batum: such a mapping should be soon is now possible.

• PHP: Detect encoding and make everything UTF-8

  - by marco92w

  Hello! I'm reading out lots of texts from various RSS feeds and inserting them into my database. Of course, there are several different character encodings used in the feeds, e.g. UTF-8 and ISO-8859-1. Unfortunately, there are sometimes problems with the encodings of the texts. Example: 1) The "ß" in "Fußball" should look like this in my database: "Ÿ". If it is a "Ÿ", it is displayed correctly. 2) Sometimes, the "ß" in "Fußball" looks like this in my database: "ß". Then it is displayed wrongly, of course. 3) In other cases, the "ß" is saved as a "ß" - so without any change. Then it is also displayed wrongly. What can I do to avoid the cases 2 and 3? How can I make everything the same encoding, preferably UTF-8? When must I use utf8_encode(), when must I use utf8_decode() (it's clear what the effect is but when must I use the functions?) and when must I do nothing with the input? Can you help me and tell me how to make everything the same encoding? Perhaps with the function mb-detect-encoding()? Can I write a function for this? So my problems are: 1) How to find out what encoding the text uses 2) How to convert it to UTF-8 - whatever the old encoding is Thanks in advance! EDIT: Would a function like this work? function correct_encoding($text) { $current_encoding = mb_detect_encoding($text, 'auto'); $text = iconv($current_encoding, 'UTF-8', $text); return $text; } I've tested it but it doesn't work. What's wrong with it?

• 2 spss and mrInterview template questions

  How can I align the mrProgress bar to be the same size as the image at the top of the table? (I'd like it below the image.)

• IE7 CSS bug aligning <img> with text in a <ul>

  - by Artem Russakovskii

  I've been banging my ahead on this IE7 bug for the last few days and it's time to resort to the mind of the crowd. I have the following HTML and CSS: http://beerpla.net/for_www/ie7_test/test.html The goal is to have a <ul>, with each <li> containing a small icon and some text. Multiline text would be aligned to itself and not wrap under the image. I've tried using float:left on the image and a bunch of other things, and finally I thought the position:absolute would work for sure but in IE7 I consistently see the text pop off to the next line and get misaligned with the image: This is what I expect it to look like: I even tried to make the div display:inline which kind of worked but then started wrapping under the image for long lines, so it was no good. zoom:1 also produced a similar effect. I'm at a loss at the moment. This code works fine in all other browsers. IE7 is a special, very special child. Any ideas? Thank you. Edit: If you have IE8, you can emulate IE7 by pressing F12 and then Alt-7.

• Microsoft Ajax Control Toolkit vs. jQuery

  - by Juri

  Hi, we are currently developing a couple of custom asp.net server controls. Now we'd like to add some Ajax support to some of them. Now basically there would be two options Microsoft Ajax & Microsoft Ajax Control Toolkit jQuery I worked already with the Control Toolkit, writing a complete Extender and it was quite intuitive, once you understand the story behind. But I also like the simplicity of jQuery. So I'd like to hear some of you what you would like to go for (advantages/disadvantages of each of them), considering also that we're mainly dealing with Microsoft technologies. Would you go more for the toolkit or jQuery,...or both? //Edit: I just made some tests and I have to admit that at the moment I find the Toolkit better due to the integration. My purpose is mainly for using it on the server controls, so with the toolkit I have corresponding classes on the server-side where I can do something like CalendarExtender toolkitCalendarExtender = new CalendarExtender(); toolkitCalendarExtender.TargetControlID.... ... this.Controls.Add(toolkitCalendarExtender); This is really nice because in this way I don't have to deal with rendering predefined JavaScript which I construct somehow as string inside my custom server control. With jQuery I would have to do so (except for the toolkit Nicolas mentioned, but the support there is too weak for using it in a professional environment) Thanks a lot.

• RotatingFileHandler throws an exception when delay parameter is set

  - by Eli Courtwright

  When I run the following code under Python 2.6 import logging from logging.handlers import RotatingFileHandler rfh = RotatingFileHandler("testing.log", delay=True) logging.getLogger().addHandler(rfh) logging.warning("Boo!") then the last line throws AttributeError: RotatingFileHandler instance has no attribute 'level'. So I add the line rfh.setLevel(logging.DEBUG) before the call to addHandler, and then the last line throws AttributeError: RotatingFileHandler instance has no attribute 'filters'. So if I manually set filters to be an empty list, then it complains about not having the attribute lock, etc. When I remove the delay=True to leave it as the default value of False as documented here, the problem completely goes away. Am I missing something? How do I properly use the delay parameter of the RotatingFileHandler class? EDIT: Upon further analysis (presented in my own answer below), this looks like a bug, but I can't find a bug report on this in the Python bug tracker, even trying different search terms, so I guess I'll report it. However, if someone can locate the actual bug report, then I can avoid submitting a duplicate reporting and wasting the time of the Python developers. I'll hold off on reporting the bug for a few hours, and if someone posts an answer that has the current bug report, then I'll accept that answer for this question.

• iOS 5.0 AVAudioPlayer Error loading audio clip: The operation couldn’t be completed. (OSStatus error -50.)

  - by Jason Catudal

  So I'm trying to test out the audio player on the iPhone, and I went off Troy Brant's iOS book. I have the Core Audio, Core Foundation, AudioToolbox, and AVFoundation frameworks added to my project. The error message I get is in the subject field. I read like 20 pages of Google search results before resorting to asking here! /sigh. Thanks if you can help. Here's my code, pretty much verbatim out of his book: NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"Yonah" ofType:@"caf"]; NSLog(@"%@", soundFilePath); NSURL *fileURL = [NSURL URLWithString:soundFilePath]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error]; if (!error) { audioPlayer.delegate = self; //audioPlayer.numberOfLoops = -1; [audioPlayer play]; } else { NSLog(@"Error loading audio clip: %@", [error localizedDescription]); } EDIT: Holy Shinto. I figured out what it was. I changed NSURL *fileURL = [NSURL URLWithString:soundFilePath]; to NSURL *fileURL = [NSURL fileURLWithPath:soundFilePath]; to the latter and I was getting a weird error, weirder than the one in the subject BUT I googled that and I changed my OS input device from my webcam to my internal microphone and guess what, it worked under the fileURLWithPath method. I'll be. Damned.

• Making Vim ubiquitous?

  - by Hamish Downer

  The Pragmatic Programmer recommends that you should use one text editor for everything. My chosen weapon editor is Vim. So I want to collect all the ways in which Vim (and the Vim keybindings) can be used and setting up your computer to make Vim work well. This includes how to embed Vim in your IDE, web browser, email client, command shell ... But I don't want Vim tips - there are other questions for them. I want tips to get into Vim, or Vim mode. Though tips about Vim mode not in an editor would be allowed (e.g. tips for vi mode when using Bash). Update: Going quite well so far, with ways to edit in Vim/gVim, or to get vi mode in Firefox, Safari, Thunderbird, many IDEs and command line applications, MS Outlook and Word. But I'm wondering if there are more. Particular applications I wonder about include OpenOffice.org KOffice Kmail Evolution Internet Explorer GIMP and Photoshop ... (only joking ;)

• Moq: Unable to cast to interface

  - by Pickels

  Hello, earlier today I asked this question. So since moq creates it's own class from an interface I wasn't able to cast it to a different class. So it got me wondering what if I created a ICustomPrincipal and tried to cast to that. This is how my mocks look: var MockHttpContext = new Mock<HttpContextBase>(); var MockPrincipal = new Mock<ICustomPrincipal>(); MockHttpContext.SetupGet(h => h.User).Returns(MockPrincipal.Object); In the method I am trying to test the follow code gives the error(again): var user = (ICustomPrincipal)httpContext.User; The error is the following: Unable to cast object of type 'IPrincipalProxy4081807111564298854aabfc890edcc8' to type 'MyProject.Web.ICustomPrincipal'. I guess I still need some practice with interfaces and moq but shouldn't I be able to cast the class that moq created back to ICustomPrincipal? I know httpContext.User returns an IPrincipal so maybe something gets lost there? Well if anybody can help me I would appreciate that. Pickels Edit: As requested the full code of the method I am testing. It's still not finished but this is what I have so far: public bool AuthorizeCore(HttpContextBase httpContext) { if (httpContext == null) { throw new ArgumentNullException("httpContext"); } var user = (ICustomPrincipal)httpContext.User; if (!user.Identity.IsAuthenticated) { return false; } return true; }

• Building Cross Platform app - recommendation

  - by Ben

  Hi, I need to build a fairly simple app but it needs to work on both PC and Mac. It also needs to be redistributable on a disc or usb drive as a standalone desktop app. Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run. I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install. However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality. Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill. What would you recommend or suggest I check out? Any suggestion much appreciated EDIT: There's a few more discussions on mono usage (though no real conclusion): Here and Here EDIT2: Titanium could also fit the bill maybe, will check it out. Any more comments from anyone? Ben

• WPF DataGrid HeaderTemplate Mysterious Padding

  - by Jake Wharton

  I am placing a single button with an image in the header of a column of a DataGrid. The cell template is also just a simple button with an image. <my:DataGridTemplateColumn> <my:DataGridTemplateColumn.HeaderTemplate> <DataTemplate> <Button ToolTip="Add New Template" Name="AddNewTemplate" Click="AddNewTemplate_Click"> <Image Source="../Resources/add.png"/> </Button> </DataTemplate> </my:DataGridTemplateColumn.HeaderTemplate> <my:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Button ToolTip="Edit Template" Name="EditTemplate" Click="EditTemplate_Click" Tag="{Binding}"> <Image Source="../Resources/pencil.png"/> </Button> </DataTemplate> </my:DataGridTemplateColumn.CellTemplate> </my:DataGridTemplateColumn> When rendered, the header has approximately 10-15px of padding on the right side only which causes the cells to obviously render at that width leaving the cell button having empty space on both sides. Being a pixel-perfectionist this annoys the hell out of me. I had initially thought that it was space for the arrows displayed when sorted but I have sorting disabled on both the entire DataGrid and explicitly on the column. Here's a image: I assume this is padding form whatever is the parent element of the button. Does anyone know a way to eliminate it?

• Structuring projects & dependencies of large winforms applications in C#

  - by Benjol

  UPDATE: This is one of my most-visited questions, and yet I still haven't really found a satisfactory solution for my project. One idea I read in an answer to another question is to create a tool which can build solutions 'on the fly' for projects that you pick from a list. I have yet to try that though. How do you structure a very large application? Multiple smallish projects/assemblies in one big solution? A few big projects? One solution per project? And how do you manage dependencies in the case where you don't have one solution. Note: I'm looking for advice based on experience, not answers you found on Google (I can do that myself). I'm currently working on an application which has upward of 80 dlls, each in its own solution. Managing the dependencies is almost a full time job. There is a custom in-house 'source control' with added functionality for copying dependency dlls all over the place. Seems like a sub-optimum solution to me, but is there a better way? Working on a solution with 80 projects would be pretty rough in practice, I fear. (Context: winforms, not web) EDIT: (If you think this is a different question, leave me a comment) It seems to me that there are interdependencies between: Project/Solution structure for an application Folder/File structure Branch structure for source control (if you use branching) But I have great difficulty separating these out to consider them individually, if that is even possible. I have asked another related question here.

• Silverlight 4, combobox databinding problem

  - by synergetic

  In my Silverlight 4 app, CustomerView (UserControl) shows Customer object as it's DataContext. Customer object has IndustryCode string property. I created combobox called cboIndustryCode and bind it to the IndustryCode property the following way: <ComboBox x:Name="cboIndustryCode" SelectedValue="{Binding IndustryCode, Mode=TwoWay}" ... /> In code-behind I populate cboIndustryCode with List of Industry object, which has Code and Name properties: cboIndustryCode.ItemsSource = industries; //which is of List<Industry> type Now, to show everything properly, in XAML I added the following: <ComboBox x:Name="cboIndustryCode" SelectedValue="{Binding IndustryCode, Mode=TwoWay}" DisplayMemberPath="Name" SelectedValuePath="Code" ... /> So, when I get a customer class from my data layer and set the DataContext to this customer instance, the cboIndustryCode properly displays industry name. But, then I edit customer (not necessarily IndustryCode) and save the object (which resets DataContext = new Customer()) and retrieve the customer again from database, and I see that cboIndustryCode no longer working. It just displays nothing, and if I select new value from the list, it does not update underlying customer object's IndustryCode property. The problem goes away, if I put the following code in the place where I set DataContext to a instance of customer, retrieved from database: Binding binding = new Binding("IndustryCode"); binding.Mode = BindingMode.TwoWay; cboIndustryCode.SetBinding(ComboBox.SelectedValueProperty, binding); So, in short, combobox's binding is reset somehow every time I save my data. Can someone tell me the reason?

• MySQL use certain columns, based on other columns

  - by Rabbott

  I have this query: SELECT COUNT(articles.id) AS count FROM articles, xml_documents, streams WHERE articles.xml_document_id = xml_documents.id AND xml_documents.stream_id = streams.id AND articles.published_at BETWEEN '2010-01-01' AND '2010-04-01' AND streams.brand_id = 7 Which just uses the default equajoin by specifying three tables in csv format in the FROM clause.. What I need to do is group this by a value found within articles.source (raw xml).. so it could turn into this: SELECT COUNT(articles.id) AS count, ExtractValue(articles.source, "/article/media_type") AS media_type FROM articles, xml_documents, streams WHERE articles.xml_document_id = xml_documents.id AND xml_documents.stream_id = streams.id AND articles.published_at BETWEEN '2010-01-01' AND '2010-04-01' AND streams.brand_id = 7 GROUP BY media_type which works fine, the problem is, I'm using rails, and using STI for the xml_documents table. The articles.source that is provided to the ExtractValue method will be of a couple different formats.. So what I need to be able to do is use "/article/media_type" IF xml_documents.type = 'source one' and use "/article/source" if xml_documents.type = 'source two' This is just because the two document types format their XML differently, but I don't want to have to run multiple queries to retrieve this information.. It would be nice if one could use a ternary operator, but i don't think this is possible.. EDIT At this Point I am looking at making a temp table, or simply using UNION to place multiple result sets together..

• Error while dynamically loading mapi32.dll

  - by The_Fox

  Our application uses Simple MAPI to send e-mails. One of our clients has problems sending e-mail from a session on his terminal server. The mapi32.dll is loaded with a call to LoadLibrary which succeeds, but then our application tries to get the addresses of the functions MAPILogon, MAPILogOff, MAPISendMail, MAPIFreeBuffer and MAPIResolveName. The problem is that GetProcAddress fails for those functions with an ERROR_ACCESS_DENIED (code: 5) except for MAPIFreeBuffer. It looks like some sort of security thing. How can I fix this or should I use another method to send mail?

• JPEG artifacts removal in C#

  - by Arcturus

  Hi all I am building a website for a club that is part of a mother organisation. I am downloading (leeching ;) ) the images that where put on profile pages of the mother organisation to show on my own page. But their website has a nice white background, and my website has a nice gray gradient on the background. This does not match nicely. So my idea was to edit the images before saving them to my server. I am using GDI+ to enhance my images, and when I use the method MakeTransparent of Bitmap, it does work, and it does do what its supposed to do, but I still have these white jpeg artifacts all over the place. The artifacts makes the image so bad, I am better off not making the image transparent and just leaving it white, but thats really ugly on my own website. I can always at a nice border with a white background of course, but I rather change the background to transparent. So I was wondering if and how I can remove some simple JPEG artifacts in C#. Has anyone ever done this before? Thanks for your time. Example image: Transformed image:

• Best Diff Tool?

  - by ila

  For all my present Diff / Merge needs I'm using Beyond Compare; when I decided to buy a license for it I tried other similar tools, both payware and freeware. Now BC is at version 3, and I think it's a great tool... but what are your experience in this field? Do you think there is something better? And what are the feature you like best on your favorite Diff tool? EDIT I'm recollecting here a list of the tools mentioned in the answers below, in order of preferences (more or less), separating pay- from free- ware and indicating supported operating system. Hope this helps.
