• mrcaseyjr Unable to insert new register in database

  I am trying to insert a new register in my database. I have created the TableAdpater for it and set the GenerateDBDirectMethods to true, so I have the Insert/Delete/Update methods available. I have a form with just one button that I use just for testing. Every time that I click that button, the following function is called in the OnClick method: MyDataDataTable.Insert("sample text","sample text","sample text","sample text"); Right after I click that button, I return to the Visual Studio 2005 Server Explorer and open the table, but no data has been inserted.

• r3n Are a DLL's Application-scoped Settings stored anywhere outside the DLL itself?

  Several other posters have noted that when a DLL contains Application-scoped Settings, their values seem to be hardcoded within the DLL, rather than saved in an external file: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=883112&SiteID=1 http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=897534&SiteID=1 http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=989609&SiteID=1 That's apparently unlike the Application-scoped Settings of an application , which get saved in <appname>.exe.config, and User-scoped Settings of a DLL, which get saved in user.config files. Using IL DASM, I can see Application-scoped Settings stored within the DLL's Properties. Can anyone confirm that these Settings are indee ...Show All

• The Cullenator How to get App.Config file path if it is created along .cs files

• Biggo Integer (Unit) Conversion Help ---

  I have an integer in the unit bytes (like kilobyte and megabyte). How can I convert it or multiply it so the unit is in gigabytes (GB) Thanks, Using this line should solve the problem: string HardDriveSize = string .Format( "{0:0.00} GB free of {1:0.00} GB" , (drive.TotalFreeSpace / (1024.0 * 1024 * 1024)), (drive.TotalSize / (1024.0 * 1024 * 1024))); This are the things that didn't work - A 1024 was missing. - Division is neccessary instead of multiplication. - You need to get a float result to get decimal places that's why I used at 1024.0 some point (you may also cast to float) - The formatting should be 0.00 Hope this helps. I have run into a problem ...Show All

  I'm trying to build a program which record desktop screen change. My program must capture screen at least 10 times per second. I'm currently using GDI to capture screen, but it take ~50% CPU usage.

• help-linux How to automatically close the parent form when the child closes.

  Hi, I have an application that uses 3 forms. Form1 contains 2 buttons - A and B. If you click Button A, then Form2 loads and Form1 is hidden. If you click Button B, then Form3 loads and Form1 is hidden. What I need to be able to do, is once Form2 has been completed by the user and then closes (by the user clicking the Finish button), for Form1 to close automatically, rather than unhiding the form and then the user having to click the button... I've searched quite a lot on how to do this, but can't find an answer. Either I'm searching for the wrong thing, or .... Could anyone provide any hints on how to do this Thanks.

• Koluns81 Visual Studio 2005 tabs missing

  For some strange reason the tabs at the bottom of certain designers aren't showing up like they used to in VS.NET; is there some setting I've inadvertently turned off e.g. when I double click on a Windows Form and it loads up in the designer, I have to either right click and select "view code" or press F7 to get into code view.
