• Visual C# DataTable + delete selected Rows

  Hi I have a data table , which gets populated at the end of a certain transaction with say 30 Rows. Now depending upon the condition the user selects, i wanted to delete certain rows as given below.But the thing here happening is, first time the fifth row gets deleted,the row count is getting changed in the table to 29, which is playing the trick here as we can see that when next delete statement isencountered, there is no row with index 29 which is throwing an error and some times the row which i want to delete is not getting deleted, instead another row with altered index is getting deleted.How can we have a workaround for this situation My intention is just to delete the rows at the specified index from the original output ...Show All

• Visual C# Graphic Child Form in MDI?

  Howdy all.  Long time listener, first time caller here...  I've recently migrated from Java over to C# and I love what I've seen thus far, especially from the MSDN community.  I was hoping someone would be able to answer a question or two for me, but such a person would have to endure a bit of backstory/mission statement.  What I'm trying to do with my newfound interest in C# is create an application that allows me to load information from a database file, create a "unit", store the information about that "unit" in a new data file, and then graphically represent that "unit" as a colored block within the area of my parent form that is NOT occupied by the menu system.  My question is this: How would I create an ...Show All

• Visual Studio SourceSafe integration and "Show Differences" dialog

  Having successfully developed a C#-usercontrol "VSSBrowser" using VSS OLE Automation, I was sad to see that it's impossible to invoke "Show Differences", "View/Edit" and "Properties" dialogs via OLE. And that's the last thing left to get a fully functional control. I googled a bit and found out that "Microsoft SourceSafe SCC Provider" (SSSCC.DLL) should be used to invoke those dialogs. I examined this DLL with "Dependency Walker" and seems I even found the necessary functions; at least two of them - SccDiff ans SccProperties. The problem is that I have no idea of how to use this API in my C# project. I couldn't find any samples or articles in the Net; at the same time I remember t ...Show All

• Visual Basic Remove all Child Nodes For given Parent Node

  All, I have a tree view with 3 Nodes on my first level. Node1, Node2 and you ve guessed it Node3. Question1: Each of the Nodes has between 50 and 100 Child Nodes. How do I delete for example Node2 and all its child nodes Question2: if I then decide I want to Add Node2 and its children again how do I put Node2 back between Node1 and Node3 again Hoep you can help Cheers Hi, a TreeNode can exist outside a TreeView so you can just store the TreeNode in a variable before removing it from the TreeView, and then re-insert the TreeNode again from the storagevariable. The example has a Form1 with an empty TreeView1 on it - make sure there's some space on the form left open, so you can click it. LeftClicking the ...Show All

• Visual C++ Help button get chm instead of hlp

  I have a application built around a CPropertySheet derived class. The help button is looking for 'app.hlp' file (this is the default MFC stuff, I've not added anything other than moving the button). How do I get it to look for a 'app.chm' file instead I've tried the following using a test help file in InitInstance() //First free the string allocated by MFC at CWinApp startup. //The string is allocated before InitInstance is called. free((void*)m_pszHelpFilePath); //Change the name of the .HLP file. //The CWinApp destructor will free the memory. m_pszHelpFilePath=_tcsdup(_T("C:\\filezilla\\filezilla.chm"));     EnableHtmlHelp(); but i just get "Failed to launch help" This is a MFC ...Show All

• Visual Studio 2008 (Pre-release) FaultContractAttribute , May 22 Build With Go-Live

  Hi, We are using the May 22 build of Wcf. This is a version with a Go-Live license. I've noticed that the FaultContract attribute can only be aplied to methods in this build. http://windowssdk.msdn.microsoft.com/en-us/library/system.servicemodel.faultcontractattribute.aspx The documentation here ( http://windowssdk.msdn.microsoft.com/en-us/library/ms733721.aspx ) has a section "Faults for the Entire Contract" For convenience, it is possible to apply the FaultContractAttribute attribute to an entire service contract as opposed to an individual operation. In that case, every operation in the service contract is able to return that type of fault. For example, in the following contract, any operation can return a MathFault: ...Show All
