  Hi, I have a problem with bindingsource component in framework 2.0. I have a combobox bound to a bindingsource which is also bound to a dataset with 2 related tables and a datagridview bound to the same bindingsource. What I want to do is : When the selectedindex property of my combobox changes, the corresponding cell value must be changed in the datagridview. But although the value in bindingsource changes, datagridview does not display the new value. That value is displayed after I move the mouse over that cell and make it invalidate its region manually. Another error I caught is the one that you can see as the subject of my post. I do not know why i have that message when I try to change the property of ((DataRowView)mybindi ...Show All

• Windows Forms How to create Arrow Line Control?

  Hi, all. If you ever used visio, you have seen the arrow link. You can put arrow link between two text boxes or image boxes. I want to create the arrow as a custom control so user can select arrow on the form and can drag it/link between two picture boxes. Does any one knows about this Any info will help! Thank you. Well, that's a bit of a bummer, please make sure you state your language preference on non-language specific forums like "Windows Forms". It shouldn't be too hard to translate the code, I've avoided any specific VB.NET short-cut. I guess what I'd tried to show in that code is that you don't have to focus on the idea of having to exactly click the "line control". Generically, t ...Show All

• Software Development for Windows Vista DIY information cards - Issue with enveloping signature

  Hi, it looks like I could need some help. My situation is following: - I create DIY cards through some homegrown Java code - I sign these DIY cards with Apache xmlsec version 1.3 (latest release). Verification works with this toolkit. - The CardSpace application always refuses to import the crd files saying " An error occurred during the import of a card. Errors in reading the imported card file. " in the event log (Event ID 260) - The signature verification seems to work (if I manipulate the signed data, I get the event description " An incoming identity could not be validated. Signature could not be verified. ") - The signature path validation seems to work (if I removed the trusted certificate, I ge ...Show All

• SQL Server Encrypting non text data

  I want to encrypt some audio files before inserting them in a SQL server database. I want to use the built in sql server encryption. I found that the encrypt by key function accepts only text (nchar,nvarchar,etc). I was thinking or reading the audio file's bytes and change them to a string and then insert them in the database. I just wanted to take opinions here. Is there a better way to do this thanks in advance Actually, the encryption functions are really designed for binary data, but we accept text variables directly for usability reasons. Unfortunately you will hit a different problem because of a design limitation on our current implementation: the output cannot be greater than 8k, therefore the plaintext has to b ...Show All

• Windows Forms highlighting

  i'm building this app, a code editor (educational purposes) and I have the GUI ready and I can save, load and do much more with it, so i'm not a total noob at C#. but i try to highlight some of the code and it works quite well. I select the code and color it. but the problem is when I try to type some more the app selects it again . so my question is: How can i make sure that the RTB deselects the selection and so that is does not select it again. here's the code: string echo = "echo"; int index = richTextBox1.Text.IndexOf(echo); if (index != -1) { richTextBox1.Select(index, echo.Length); richTextBox1.SelectionColor = Color.Blue; index = richTextBox1.Text.IndexOf(echo, index + echo. ...Show All

• Software Development for Windows Vista Picture taken date missing

  Hello Windows Vista 32bit Ultimate (German): Sometimes the EXIF-data "date picture taken" (in German "Aufnahmedatum") is empty in Windows Explorer. Escpecially if I edit the JPG-Image with PaintShopPro 11 and save it, the date will be empty in explorer view, but still exists in EXIF-Tags.

Maybe in Windows Vista Explorer there is shown a wrong EXIF-Tag Best regards I too have a new Dell Inspiron 1520 laptop running Vista Home Edition. Copied photos from Windows98 ...Show All

• Visual Studio 2008 (Pre-release) Binding Lost after changing Image.Source

  In my code, I have a WPF Image control bound to a property of an entity class. The binding is configured so that source updates are explicit: <Image Source="{Binding Path=ImageData, UpdateSourceTrigger=Explicit}" ... /> The application allows the user to change the image displayed by displaying a file dialog, then setting the Image.Source property to the selected image file like this: this.imageControl.Source = new BitmapImage(new Uri(selectedFileName)); When the user selects to save the current info, the code calls the following to explicitly update the binding source of the Image control: this.imageControl.GetBindingExpression(Image.SourceProperty).UpdateSource(); an exception is thrown because the GetBindingExpress ...Show All
