  • Show image from clipboard to defalut imageviewer of windows using c#.net

    - by Rajesh Rolen- DotNet Developer
    I am using below function to make a image of current form and set it in clipboard Image bit = new Bitmap(this.Width, this.Height); Graphics gs = Graphics.FromImage(bit); gs.CopyFromScreen(this.Location, new Point(0, 0), bit.Size); Guid guid = System.Guid.NewGuid(); string FileName = guid.ToString(); //Copy that image in the clipbaord. Image imgToCopy = Image.FromFile(Path.Combine(Environment.CurrentDirectory, FileName + ".jpg")); Clipboard.SetImage(imgToCopy); Now my image is in clipboard and i am able to show it in picturebox on other form using below code : mypicturebox.Image = Clipboard.GetImage(); Now the the problem is that i want to show it in default imageviewer of that system. so for that i think using "System.Diagnostics.Process.Start" we can do that.. but i dont know, how to find default imageviewer and how to set clipboard's image in that ... please help me out... if i find solution than thats good otherwise i am thinking to save that file from clipboard to harddisk and then view it in window's default imageviewer... please help me to resolve my problem.. i am using c#.net

  • Windows theme affecting ListView header

    - by LihO
    I've created new Windows Forms Application (C#) with one simple form containing ListView. Then I changed the View Property to Details and increased the size of the font used in this ListView and here's the result: This is how it looks on Windows XP with Windows Classic theme: and here's the result with Windows XP theme: Creating the same Windows Forms Application in Visual C++ instead of C# yields same result. EDIT : Thanks to Kamil Lach, we already know that Visual Styles is what makes the appearance of ListView change. This can be avoided either by removing Application.EnableVisualStyles() call or by changing the Application.VisualStyleState. Both of these solutions yield the following result: This looks fine, but this change affects the appearance of other controls which is not good. I'd like my ListView to be the only control that is not affected by Visual Styles. I've also found similar questions that try to deal with it: Can you turn off visual styles/theming for just a single windows control? How do I disable visual styles for just one control, and not its children? Unfortunately, none of mentioned solutions works. Any C# solution that would make the ListView header have the correct height would be appreciated.

  • ASP.Net Response Filter Causing SharePoint 2010 "Unexpected Error"

    - by Jason Weber
    Hello everyone, I'm debugging an HttpModule with an ASP.NET response filter. This dynamically rewrites portions of rendered SharePoint WCM pages. The publishing pages render fine in SP2007 on both Server 2003 and Server 2008. However the equivalent pages fail to render in SP2010 B2 on Server 2008 R2. The generic "An unexpected error has occurred message" page is displayed. This error only happens when the response filter is applied to an .aspx page. Other page types, such as .css, render fine on this platform. This error also happens when the response filter does not modify the page at all (pure pass-through). This KB article seems very closely related: http://support.microsoft.com/kb/2014472. However, this same error occurs with caching disabled. I see no related entries in any of the following: ULS for SP, Event Log, Failed Request Tracing (IIS7). Running under the debugger suggests that the custom code is not raising any exceptions. Any help or insight would be greatly appreciated.

  • Creating a desktop icon using JWS JNLP for a JavaFX app.

    - by Sleepycat
    I am trying to get a custom destop icon to be displayed for my app but for some reason no matter what I do the same default java icon shows up. I have tried everything I can think of and gone and compared my jnlp file with others whose icons seem to work ok. According to everything I have read the following should work fine. But of course, it doesn't: <information> <title>MikesApp</title> <vendor>Mike</vendor> <homepage href="http://www.mikesapp.com/"/> <description>Mikes App.</description> <icon kind="shortcut" href="res/icon64x64.png" width="64" height="64"/> <offline-allowed/> <shortcut> <desktop/> </shortcut> </information> Any ideas would be greatly appreciated.

  • Vertical crosshair reposition on Google Map after map resize Issue

    - by joe
    I use the following function to add a crosshair to my Google Map. It works great for horizontal resizing. I can not figure out how to make it work for vertical. After resizing the map it requires the user to either zoom in or out 1 layer, upon which the crosshair snaps to center. var crosshairsSize=17; GMap2.prototype.addCrosshairs=function(){ var container=this.getContainer(); if(this.crosshairs){$(this.crosshairs).remove();} var crosshairs=document.createElement("img"); crosshairs.src='../images/crosshair2.gif'; crosshairs.style.width=crosshairsSize+'px'; crosshairs.style.height=crosshairsSize+'px'; crosshairs.style.border='0'; crosshairs.style.position='relative'; crosshairs.style.top=((parseInt(container.clientHeight)-crosshairsSize)/2)+'px'; crosshairs.style.left="0px"; // The map is centered so 0 will do crosshairs.style.zIndex='500'; container.appendChild(crosshairs); this.crosshairs=crosshairs; return crosshairs;}; I use map.checkResize(); and the map is correct, it's just the crosshair that is off. I've tried firing a javascript zoom in one level but it doesn't work like zooming in with the mouse. It's only zooming in/out with the mouse scroll wheel too... clicking and dragging the zoom slider doesn't work so somehow it's liking the mouse scroll wheel. Firing addCrosshairs(); after resize makes no difference. It places the new crosshair in old spot and still requires a mouse scroll zoom.

  • Assigning figure size to a figure with a given handle (MATLAB)

    - by James
    Hi, is there a way to assign the outerposition property of a figure to a figure with a given handle? For example, if I wanted to define a figure as say figure 1, I would use: figure(1) imagesc(Arrayname) % I.e. any array I can also change the properties of a figure using the code: figure('Name', 'Name of figure','NumberTitle','off','OuterPosition',[scrsz(1) scrsz(2) 700 700]); Is there a propertyname I can use to assign the outerposition property to the figure assigned as figure 1? The reason I am asking this is because I am using a command called save2word (from the MATLAB file exchange) to save some plots from a function I have made to a word file, and I want to limit the number of figures I have open as it does this. The rest of the code I have is: plottedloops = [1, 5:5:100]; % Specifies which loops I want to save GetGeometry = getappdata(0, 'GeometryAtEachLoop') % Obtains a 4D array containing geometry information at each loop NumSections = size(GetGeometry,4); %Defined by the fourth dimension of the 4D array for j = 1:NumSections for i = 1:plottedloops P = GetGeometry(:,:,i,j); TitleSize = 14; Fsize = 8; % Save Geometry scrsz = get(0,'ScreenSize'); %left, bottom, width height figure('Name', 'Geometry at each loop','NumberTitle','off','OuterPosition',[scrsz(1) scrsz(2) 700 700]); This specifies the figure name, dims etc., but also means multiple figures are opened as the command runs. % I have tried this, but it doesn't work: % figure(0, 'OuterPosition',[scrsz(1) scrsz(2) 700 700]); imagesc(P), title('Geometry','FontSize', TitleSize), axis([0 100 0 100]); text(20,110,['Loop:',num2str(i)], 'FontSize', TitleSize); % Show loop in figure text(70,110,['Section:',num2str(j)], 'FontSize', TitleSize);% Show Section number in figure save2word('Geometry at each loop'); % Saves figure to a word file end end Thanks

  • InlineUIControl

    - by zync
    Hi. I have a project in wich I must create a form editor (just like infopath) using wpf. For this I thought to use a RichTextBox and in there I would place InlineUIElements with the different controls (TextBox, ComboBox, etc.). The problem is that I can't change some properties associated with those controls. Here's some XAML: <RichTextBox> <FlowDocument> <Paragraph> <InlineUIContainer> <TextBox Background="Red">Some Text</TextBox> </InlineUIContainer> </Paragraph> </FlowDocument> </RichTextBox> This displays a TextBox in a RichTextBox just like I wanted but it's not red. Some other properties work like width and height. Why is this and how can I make it work? Other question is: Am I approaching the problem (creating the form editor) right? Thanks

  • Add Ellipsis to a Path in a WinForms Program without Win32 API call (revisited)

    - by casterle
    I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }

  • passing in javascript values into iframe tag

    - by Cedar Jensen
    What's the best way to pass in the value held in a javascript variable into an iframe call on the same html page? I'm trying to improve my site's page response times by moving ad serving javascript code (the typical document.write('<script type="text/javascript" src="..") into a separate iframe. (Based on this posting) The request to the ad server typically require a seed variable declared once per site and incremented each time page is loaded by the client. What I want to do is pass in the seed variable into the document invoked by my iframe section. The seed variable is initialized in the 'head' tag of my main html document: <head> <script type="text/javascript"> <!-- custom_seed=1; //--> </script> </head> Later in the html document, I make the request through an iframe which returns the html necessary to invoke the ad server. <body> <!-- a bunch of html to display the page --> <iframe src="somepage.html" width="100%" height="100%"> <p>No support for iframe</p> </iframe> </body> The html returned in the 'somepage.html' has a script used to call the ad server and needs to use the earlier declared seed variable as a parameter: <script type="text/javascript"> document.write('<script type="text/javascript" src="http://ad.server.net/...seed='+ custom_seed +'?"></script>'); custom_seed++; </script> What's a good way to achieve this?

  • WPF DataBinding to standard CLR properties in code-behind

    - by nukefusion
    Hi everyone, Just learning WPF databinding and have a gap in my understanding. I've seen a few similar questions on StackOverflow, but I'm still struggling in determining what I have done wrong. I have a simple Person class with a Firstname and Surname property (standard CLR properties). I also have a standard CLR property on my Window class that exposes an instance of Person. I've then got some XAML, with two methods of binding. The first works, the second doesn't. Can anybody help me to understand why the second method fails? There's no binding error message in the Output log. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300" DataContext="{Binding RelativeSource={RelativeSource Self}, Path=MyPerson}"> <StackPanel> <Label>My Person</Label> <WrapPanel> <Label>First Name:</Label> <Label Content="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=MyPerson.FirstName}"></Label> </WrapPanel> <WrapPanel> <Label>Last Name:</Label> <Label Content="{Binding MyPerson.Surname}"></Label> </WrapPanel> </StackPanel> Edit: Ok, thanks so far. I've changed the second expression to: <Label Content="{Binding Surname}"></Label> I still can't get it to work though!

  • Drawing only part of a texture OpenGL ES iPhone

    - by Ben Reeves
    ..Continued on from my previous question I have a 320*480 RGB565 framebuffer which I wish to draw using OpenGL ES 1.0 on the iPhone. - (void)setupView { glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteriv(GL_TEXTURE_2D, GL_TEXTURE_CROP_RECT_OES, (int[4]){0, 0, 480, 320}); glEnable(GL_TEXTURE_2D); } // Updates the OpenGL view when the timer fires - (void)drawView { // Make sure that you are drawing to the current context [EAGLContext setCurrentContext:context]; //Get the 320*480 buffer const int8_t * frameBuf = [source getNextBuffer]; //Create enough storage for a 512x512 power of 2 texture int8_t lBuf[2*512*512]; memcpy (lBuf, frameBuf, 320*480*2); //Upload the texture glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 512, 512, 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, lBuf); //Draw it glDrawTexiOES(0, 0, 1, 480, 320); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } If I produce the original texture in 512*512 the output is cropped incorrectly but other than that looks fine. However using the require output size of 320*480 everything is distorted and messed up. I'm pretty sure it's the way I'm copying the framebuffer into the new 512*512 buffer. I have tried this routine int8_t lBuf[512][512][2]; const char * frameDataP = frameData; for (int ii = 0; ii < 480; ++ii) { memcpy(lBuf[ii], frameDataP, 320); frameDataP += 320; } Which is better, but the width appears to be stretched and the height is messed up. Any help appreciated.

  • Making alpha PNGs with PHP GD

    - by WiseDonkey
    Hello, I've got a problem making alpha PNGs with PHP GD. I don't have imageMagik etc. Though the images load perfectly well in-browser and in GFX programs, I'm getting problems with Flash AS3 (actionscript) understanding the files. It complains of being an unknown type. But, exporting these files from Fireworks to the same spec works fine. So I'm suggesting it's something wrong with the formatting in PHP GD. There seems to be a number of ways of doing this, with several similar functions; so maybe this isn't right? $image_p = imagecreatetruecolor($width_orig, $height_orig); $image = imagecreatefrompng($filename); imagealphablending($image_p, false); ImageSaveAlpha($image_p, true); ImageFill($image_p, 0, 0, IMG_COLOR_TRANSPARENT); imagealphablending($image_p, true); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width_orig, $height_orig, $width_orig, $height_orig); imagepng($image_p, "new2/".$filename, 0); imagedestroy($image_p); This just takes files it's given and puts them into new files with a specified width/height - for this example it's same as original but in production it resizes, which is why I'm resampling.

  • How to use DLL reference with an ActiveX <object> via JavaScript

    - by John Factorial
    My question: how can I set an ActiveX object's property via JavaScript to an enum value found in a non-ActiveX DLL? Problem description: I am instantiating an ActiveX object with the following object tag: <object classid="clsid:F338193D-2491-4D7B-80CE-03487041A278" id="VideoCapture1" width="500" height="500"></object> (This is the guid for the 3rd party ActiveX I'm using, "VisioForge_Video_Capture_4.VFVideoCapture4X") I have example C# code for using this ActiveX, which I am porting to JavaScript. Code like this works just fine: VideoCapture1.Debug_Mode = true; var devcount = VideoCapture1.Video_CaptureDevices_GetCount(); var devs = []; for (var i =0; i < devcount; ++i) { devs[devs.length] = VideoCapture1.Video_CaptureDevices_GetItem(i); } ... etc ... However, VideoCapture1 has some settings which refer to a DLL enum, like so (C# code): VideoCapture1.Mode = VisioForge_Video_Capture_4.TxVFMode.Mode_Video_Preview; I can see in Visual Web Developer that TxVFMode.Mode_Video_Preview is value 1 in the enum. However, the following JS does not appear to set the Mode properly: VideoCapture1.Mode = 1; Does anyone know how I can set VideoCapture1.Mode to the enum value found in the TxVFMode? PS: In Visual Web Developer, when I "Go to definition" on TxVFMode, I get the Guid for the enum. I thought I could create an with this Guid or instantiate a VisioForge_Video_Capture_4.TxVFMode in JS, but neither gives me a usable object.

  • WPF Grid Column MaxWidth not enforced

    - by Trevor Hartman
    This problem stems from not being able to get my TextBlock to wrap. Basically as a last-ditch attempt I am setting MaxWidth on my container grid's columns. I was surprised to find that my child label and textbox still do whatever they want (bad children, BAD) and are not limited by my grid column's MaxWidth="200". What I'm really trying to do is let my TextBlock fill available width and wrap if necessary. So far after trying many variations of HorizontalAlignment="Stretch" on every known parent in the universe, nothing works, except setting an explicit MaxWidth="400" or whatever number on the TextBlock. This is not good because I need the TextBlock to fill available width, not be limited by some fixed number. Thanks! <ItemsControl> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition MaxWidth="200" SharedSizeGroup="A" /> <ColumnDefinition MaxWidth="200" SharedSizeGroup="B" /> </Grid.ColumnDefinitions> <Label VerticalAlignment="Top" Margin="0 5 0 0" Grid.Column="0" Style="{StaticResource LabelStyle}" Width="Auto" Content="{Binding Value.Summary}" /> <TextBlock Grid.Column="1" Margin="5,8,5,8" FontWeight="Normal" Background="AliceBlue" Foreground="Black" Text="{Binding Value.Description}" HorizontalAlignment="Stretch" TextWrapping="Wrap" Height="Auto" /> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl>

I have added the following line to the my sites-enabled file: AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript application/excel But is seems to make the response data bigger??? Using firebug, without the module I downloaded the xls spreadsheet from the application and it downloaded 100Kb of data, the file size once on the filesystem was also 100Kb as expected. Once I enabled the deflate module as described above and repeated the process, the amount of data downloaded was 295Kb?? but the file was still only 100Kb once save on the filesystem. As an experiment I manually gzipped the saved xls file and it compressed to 20Kb. What am I doing wrong here?

  • Mouse move panning

    - by Rudy
    Hi all, I'm trying to scroll a series of thumbnails horizontally based on the mouseX position. I can get it to scroll but it's very choppy and for some reason it's not reading my start and end numbers so it will stop scrolling. Can anyone point me in the right direction? Thanks. var thumbBounds:Object = new Object(); thumbBounds = thumbContainer.getBounds(this); thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); private function setScrolling(me:MouseEvent):void { thumbContainer.removeEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.addEventListener(Event.ENTER_FRAME, scrollThumbs); } private function scrollThumbs(e:Event):void { if(mouseX <= thumbBounds.x || mouseX thumbBounds.width || mouseX < thumbBounds.y || mouseX thumbBounds.height) { thumbContainer.addEventListener(MouseEvent.MOUSE_OVER, setScrolling); stage.removeEventListener(Event.ENTER_FRAME, scrollThumbs); } if(thumbContainer.x = 0) { thumbContainer.x = 0; } if(thumbContainer.x <= -842) { thumbContainer.x = -842; } var xdist:Number = new Number(); xdist = mouseX - 382; thumbContainer.x += Math.round(-xdist / 10); }

  • vertical-align="middle" for td is not working if we use <!doctype ...>

    - by Manohar
    Hi, I am trying to middle align an element, But I have bumped into this problem. I am using this tag: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <body> <table style="width:100%; height: 100%" cellspacing="0" cellpadding="0"> <tr> <td vertical-align="middle"> <div id="progressContainer" style="text-align:center;"> Some string here </div> </td> </tr> </table> </body> </html> If I remove this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">, its middle aligned properly. Question: Am I doing anything wrong here?

  • Dynamically add columns to a listbox

    - by mgroves
    I'm brand new to Windows Phone 7 development, and almost as equally new to Silverlight. I have a ListBox with a DataTemplate, StackPanel, and TextBlocks like so: <ListBox Height="355" HorizontalAlignment="Left" Margin="6,291,0,0" Name="detailsList" VerticalAlignment="Top" Width="474" Background="#36FFFFFF"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Width="50" Text="{Binding Ticker}" /> <TextBlock Width="50" Text="{Binding Price}" /> <TextBlock Width="50" Text="{Binding GainLoss}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> I have some C# code to populate it: var info = new List<StockInfo>(); info.Add(new StockInfo { Ticker = "C", Price = "5.18", GainLoss = "10" }); info.Add(new StockInfo { Ticker = "WEN", Price = "4.18", GainLoss = "12" }); info.Add(new StockInfo { Ticker = "CBB", Price = "5.22", GainLoss = "210" }); detailsList.ItemsSource = info; And that all works fine. My question is: how do I add/remove additional 'textblocks' to the listbox dynamically (at runtime)? Also, how do I put column headers on the list box?

  • Good mobile oriented GWT widget library alternatives

    - by Michael Donohue
    I've been developing a travel planning site - tripgrep.com - which is built on appengine, GWT and smartgwt, among other technologies. It is still early days, and the site is now working well on my development environment, which is either a windows or mac computer. However, I am frequently talking up the website to my friends when we are at a bar or other venue, so I am standing there while they try to access the site via an iPhone, Android or Blackberry - I've witnessed all three. It has been painfully obvious that the browser based frontend takes a long time to download on a mobile device. I am pretty sure this is because of the javascript download for SmartGWT. So, I would like to look at alternatives to SmartGWT. What I like about SmartGWT is that it has a reasonable look and feel out of the box - I don't need to learn any design or css and it has an office application look. This is considerably better than the GWT built-in widgets, which just get a blue border. The better look-and-feel is why I went with SmartGWT early on. However, the slow load times are killing me on these mobile demos. So now I want a fast loading widget alternative that has good look-and-feel out of the box. The features I care about are: tabs, good form layout, Google maps API integration, grid data viewing. If those are all available in a library that loads quickly on a mobile device, then that's the library I want.
