  • If Key Value pair exists in multidimensional array.. How to?

    - by Daniel White
    I have a codeigniter shopping cart going and its "cart" array is the following: Array ( [a87ff679a2f3e71d9181a67b7542122c] => Array ( [rowid] => a87ff679a2f3e71d9181a67b7542122c [id] => 4 [qty] => 1 [price] => 12.95 [name] => Maroon Choir Stole [image] => 2353463627maroon_3.jpg [custprod] => 0 [subtotal] => 12.95 ) [8f14e45fceea167a5a36dedd4bea2543] => Array ( [rowid] => 8f14e45fceea167a5a36dedd4bea2543 [id] => 7 [qty] => 1 [price] => 12.95 [name] => Shiny Red Choir Stole [image] => 2899638984red_vstole_1.jpg [custprod] => 0 [subtotal] => 12.95 ) [eccbc87e4b5ce2fe28308fd9f2a7baf3] => Array ( [rowid] => eccbc87e4b5ce2fe28308fd9f2a7baf3 [id] => 3 [qty] => 1 [price] => 14.95 [name] => Royal Blue Choir Stole [image] => 1270984005royal_vstole.jpg [custprod] => 1 [subtotal] => 14.95 ) ) My goal is to loop through this multidimensional array some how and if ANY product with the key value pair "custprod == 1" exists, then my checkout page will display one thing, and if no custom products are in the cart it displays another thing. Any help is appreciated. Thanks.

  • On XP, how do I get the tooltip to appear above a transclucent form?

    - by Daniel Stutzbach
    I have an form with an Opacity less then 1.0. I have a tooltip associated with a label on the form. When I hover the mouse over the label, the tooltip shows up under the form instead of over the form. If I leave the Opacity at its default value of 1.0, the tooltip correctly appears over the form. However, my form is obviously no longer translucent. ;-) I have tried manually adjusting the position of the ToolTip with SetWindowPos() and creating a ToolTip "by hand" using CreateWindowEx(), but the problem remains. This makes me suspect its a Win32 API problem, not a problem with the Windows Forms implementation that runs on top of Win32. Why does the tooltip appear under the form, and, more importantly, how can I get it to appear over the form where it should? Edit: this appears to be an XP-only problem. Vista and Windows 7 work correctly. I'd still like to find a workaround to get the tooltip to appear above the form on XP. Here is a minimal program to demonstrate the problem: using System; using System.Windows.Forms; public class Form1 : Form { private ToolTip toolTip1; private Label label1; [STAThread] static void Main() { Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); Application.Run(new Form1()); } public Form1() { toolTip1 = new ToolTip(); label1 = new Label(); label1.Location = new System.Drawing.Point(105, 127); label1.Text = "Hover over me"; label1.AutoSize = true; toolTip1.SetToolTip(label1, "This is a moderately long string, " + "designed to be very long so that it will also be quite long."); ClientSize = new System.Drawing.Size(292, 268); Controls.Add(label1); Opacity = 0.8; } }

  • VS 2008 Code Snippet Indentation

    - by Daniel
    In VS 2008, there are XML code snippets that seem to be pretty awesome :) However, it seems that the snippets we created do not indent properly. For example if we have the following code: { ... { ... { InsertSnippet here. We get something like: { ... { ... { FirstLineofSnippet SecondLineOfSnippet ThirdLineOfSnippet Is there any way to make it so that all lines keep the same indentation?

  • What's the "right" way to get Win32 p/Invoke declarations?

    - by Daniel Earwicker
    I typically use the site http://www.pinvoke.net/ to grab a DllImport declaration whenever I need to call a Win32 API, and I've noticed it's the de facto standard response on Stack Overflow to API interop questions. Is this what "everyone" does? Is there a better way? Does Microsoft offer an alternative? e.g. a tool that reads .h files and outputs an assembly. Why aren't there some standard assemblies that just expose all the Win32 APIs? What would be the barrier to creating them and using them, as an alternative to a site like pinvoke.net?

  • EXCEL import to sql returning NULL for decimals when in VARCHAR data type

    - by Daniel
    Hi, I am working on a peice of software which has expodentially grown over the last few years and the database needs to be regularly updated. Customers are providing us with data now on large spreadsheets which we format and will start importing into the database. I am using the Import and Export Data (32-bit) Wizard. One column in the database contains values like '1.1.1.2' etc and i am importing them in as a Varchar as that is the data type in the database. However, for values like '8.5', 'NULL' is getting imported insead. It only occurs when there is one decimal point. Is this a formatting error with excel or is it the wrong datatype?

  • Copy an array backwards? Array.Copy?

    - by daniel
    I have a List<T> that I want to be able to copy to an array backwards, meaning start from List.Count and copy maybe 5 items starting at the end of the list and working its way backwards. I could do this with a simple reverse for loop; however there is probably a faster/more efficient way of doing this so I thought I should ask. Can I use Array.Copy somehow? Originally I was using a Queue as that pops it off in the correct order I need, but I now need to pop off multiple items at once into an array and I thought a list would be faster.

  • How do I fix the alpha value after calling GDI text functions?

    - by Daniel Stutzbach
    I have a application that uses the Aero glass effect, so each pixel has an alpha value in addition to red, green, and blue values. I have one custom-draw control that has a solid white background (alpha = 255). I would like to draw solid text on the control using the GDI text functions. However, these functions set the alpha value to an arbitrary value, causing the text to translucently show whatever window is beneath my application's. After calling rendering the text, I would like to go through all of the pixels in the control and set their alpha value back to 255. What's the best way to do that? I haven't had any luck with the BitBlt, GetPixel, and SetPixel functions. They appear to be oblivious to the alpha value. Here are other solutions that I have considered and rejected: Draw to a bitmap, then copy the bitmap to the device: With this approach, the text rendering does not make use of the characteristics of the monitor (e.g., ClearText). Use GDI+ for text rendering: This application originally used GDI+ for text rendering (before I started working on Aero support). I switched to GDI because of difficulties I encountered trying to accurately measure strings with GDI+. I'd rather not switch back. Set the Aero region to avoid the control in question: My application's window is actually a child window of a different application running in a different process. I don't have direct control over the Aero settings on the top-level window. The application is written in C# using Windows Forms, though I'm not above using Interop to call Win32 API functions.

  • Making uppercase of std::string

    - by Daniel K.
    Which implementation do you think is better? std::string ToUpper( const std::string& source ) { std::string result; result.reserve( source.length() ); std::transform( source.begin(), source.end(), result.begin(), std::ptr_fun<int, int>( std::toupper ) ); return result; } and... std::string ToUpper( const std::string& source ) { std::string result( source.length(), '\0' ); std::transform( source.begin(), source.end(), result.begin(), std::ptr_fun<int, int>( std::toupper ) ); return result; } Difference is that the first one uses reserve method after the default constructor, but the second one uses the constructor accepting the number of characters.

  • How to handle User Authentication for program in client’s local machine?

    - by Daniel
    Which user authentication scheme could be used at following scenario? 1.Application A developed by my company is installed at user's local computer. 2.Users login at my company's website. 3.If login is successful, access to the application A in user's local machine is granted. The development environment is .NET. Is there a secure way to authenticate the user to access the application? I've thought about encrypting the login information entered at the website, and then sending that information to the program at user's local machine for authentication. but I think as long as the client program has the decrypting ability, it is vulnerabe to decompiling,etc. Thanks in advance!

  • Dynamic upsert in postgresql

    - by Daniel
    I have this upsert function that allows me to modify the fill_rate column of a row. CREATE FUNCTION upsert_fillrate_alarming(integer, boolean) RETURNS VOID AS ' DECLARE num ALIAS FOR $1; dat ALIAS FOR $2; BEGIN LOOP -- First try to update. UPDATE alarming SET fill_rate = dat WHERE equipid = num; IF FOUND THEN RETURN; END IF; -- Since its not there we try to insert the key -- Notice if we had a concurent key insertion we would error BEGIN INSERT INTO alarming (equipid, fill_rate) VALUES (num, dat); RETURN; EXCEPTION WHEN unique_violation THEN -- Loop and try the update again END; END LOOP; END; ' LANGUAGE 'plpgsql'; Is it possible to modify this function to take a column argument as well? Extra bonus points if there is a way to modify the function to take a column and a table.

  • PHP to C# and Vice versa

    - by Daniel Sh.
    I'm in this project: A web page that's gonna be used by the front-end company people to query and update data from a SQL DB. I'm working with visual studio and the code behind (C#) is almost done, so the interactions between SQL and C# and ok. My original idea was to work with ASP.NET which is familiar to me, but that's not gonna be possible. I have to switch to PHP. So, today is my first day learning PHP, checking http://php.net/manual/en/index.php and a lot of things seem quite similar to ASP.NET so I guess it won't be that hard. Anyways, some questions popped up quite fast as I wanted to script something else than a "hello world" . Is there an easy way to get/send C# variables from my class using a php page? I've read soemthing about using XML in order to do so, but still I'm scratching my head, is there another, easier, way to do this?

  • A few problems with Delphi involving Mail Merge, SQL + Databases.

    - by Daniel
    My first problem is with mail merge. I have created a a Data File and a table, yet I am not able to fill my table with information from my Data File. The << just seems to be inserted after wherever the cursor is on the page, which is not where the table is. All that is entered into the actual table is a '59'. Therefore I think I either need to to change the code or be able to move the cursor. Here is the code I am currently using: wrdDoc.Tables.Add(wrdSelection.Range, ADOTable1.FieldCount, 3); wrdDoc.Tables.Item(1).Columns.Item(1).SetWidth(51,wdAdjustNone); wrdDoc.Tables.Item(1).Columns.Item(2).SetWidth(20,wdAdjustNone); wrdDoc.Tables.Item(1).Columns.Item(3).SetWidth(100,wdAdjustNone); // Set the shading on the first row to light gray wrdDoc.Tables.Item(1).Rows.Item(1).Cells .Shading.BackgroundPatternColorIndex := wdGray25; // BOLD the first row wrdDoc.Tables.Item(1).Rows.Item(1).Range.Bold := True; // Center the text in Cell (1,1) wrdDoc.Tables.Item(1).Cell(1,1).Range.Paragraphs.Alignment := wdAlignParagraphCenter; // Fill each row of the table with data wrdDoc.Tables.Item(1).Cell(1, 1).Range.InsertAfter('Time'); wrdDoc.Tables.Item(1).Cell(1, 2).Range.InsertAfter(''); wrdDoc.Tables.Item(1).Cell(1, 3).Range.InsertAfter('Teacher'); For Count := 1 to (ADOTable1.FieldCount - 1) do begin wrdDoc.Tables.Item(1).Cell((Count + 1), 1).Range.InsertAfter(wrdSelection.Range,'Time' + IntToStr(Count)); wrdDoc.Tables.Item(1).Cell((Count + 1), 2).Range.InsertAfter(wrdSelection.Range,'THonorific' + IntToStr(Count)); wrdDoc.Tables.Item(1).Cell((Count + 1), 3).Range.InsertAfter(wrdSelection.Range,'TSurname' + IntToStr(Count)); end; My second problem is that I do not know what the correct SQL syntax is for editing the name of a column in the database (I am using Delphi 7 and Microsoft Jet Engine if that makes a difference). The third problem is that when I add a new column to my database manually (which I need to do) I get a 'violation' error in one of my units when I activate an ADOTable. This only happens on one unit and it happens when I add a column with any name anywhere in the table. I know that is vague but I can't seem to narrow down the problem any further than that. If you could help with me with any of those it would be great. Thanks.

  • How to get function's name from function's pointer in C?

    - by Daniel Silveira
    How to get function's name from function's pointer in C? Edit: The real case is: I'm writing a linux kernel module and I'm calling kernel functions. Some of these functions are pointers and I want to inspect the code of that function in the kernel source. But I don't know which function it is pointing to. I thought it could be done because, when the system fails (kernel panic) it prints out in the screen the current callstack with function's names. But, I guess I was wrong... am I?

  • .NET immutable object usage best practices? Should I be using them as much as possible?

    - by Daniel
    Say I have a simple object such as class Something { public int SomeInt { get; set; } } I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such: class ImmutableSomething { public int SomeInt { get { return m_someInt; } } private int m_someInt = 0; public void ChangeSomeInt(int newValue) { m_someInt = newvalue; } } What do you reckon?

  • How can I write a file on an sftp-server with PHP?

    - by Daniel
    Hi, I hope someone here could help me, because I couldn't find any solution with Google. What I have to do is to generate a XML-string (that works) an save that directly into a file on an sftp-server. So far, so good... I used the following code with ftp and it works to, but not with ftps. So I either need another options-configuration for the stream or a different way to solve that task. Here my current code: $host = 'ftp.example.com'; $port = 22; $user = 'xxxxxx'; $pass = 'xxxxxx'; $file = 'test_' . time() . '.txt'; $ftpPath = sprintf('ftp://%s:%s@%s:%d/%s', $user, $pass, $host, $port, $file); $context = stream_context_create(array('ftp' = array('overwrite' = true))); file_put_contents($ftpPath, 'test', 0, $context);

  • sql server 2005 replication article conflict

    - by Daniel
    Hi all, I have a sql server 2005 database that I want to setup replication for. The problem is that the database has two schemas both of which have a table with the same name in it. For some reason even though the tables are in different schemas the replication creation fails when done through management studio due to conflicting article names (i assume its trying to create the same name for both tables in the different schemas). Is there any workaround for doing this in the studio, I can probably write a script or program to do this but just for this one thign is a bit annoying and it probably wont be allowed to run in production. Perhaps there is a hot fix or something I'm not aware about? Cheers,

  • NHibernate : Root collection with an root object

    - by Daniel
    Hi, I want to track a list of root objects which are not contained by any element. I want the following pseudo code to work: IList<FavoriteItem> list = session.Linq<FavoriteItem>().ToList(); list.Add(item1); list.Add(item2); list.Remove(item3); list.Remove(item4); var item5 = list.First(i => i.Name = "Foo"); item5.Name = "Bar"; session.Save(list); This should automatically insert item1 and item2, delete item3 and item3 and update item5 (i.e. I don't want to call sesssion.SaveOrUpdate() for all items separately. Is it possible to define a pseudo entity that is not associated with a table? For example I want to define the class Favorites and map 2 collection properties of it and than I want to write code like this: var favs = session.Linq<Favorites>(); favs.FavoriteColors.Add(new FavoriteColor(...)); favs.FavoriteMovies.Add(new FavoriteMovie(...)); session.SaveOrUpdate(favs); FavoriteColors and FavoriteMovies are the only properties of the Favorites class and are of type IList and IList. I do only want to persist the these two collection properties but not the Favorites class. Any help is much appreciated.

  • How can you determine the file size in JavaScript?

    - by Daniel Lew
    I help moderate a forum online, and on this forum we restrict the size of signatures. At the moment we test this via a simple Greasemonkey script I wrote; we wrap all signatures with a <div>, the script looks for them, and then measures the div's height and width. All the script does right now is make sure the signature resides in a particular height/width. I would like to start measuring the file size of the images inside of a signature automatically so that the script can automatically flag users who are including huge images in their signature. However, I can't seem to find a way to measure the size of images loaded on the page. I've searched and found a property special to IE (element.fileSize) but I obviously can't use that in my Greasemonkey script. Is there a way to find out the file size of an image in Firefox via JavaScript? Edit: People are misinterpreting the problem. The forums themselves do not host images; we host the BBCode that people enter as their signature. So, for example, people enter this: This is my signature, check out my [url=http://google.com]awesome website[/url]! This image is cool! [img]http://image.gif[/img] I want to be able to check on these images via Greasemonkey. I could write a batch script to scan all of these instead, but I'm just wondering if there's a way to augment my current script.
