• Visual C++ Again with COM

  Hello there, I have a DLL that uses a COM object .

• SQL Server SRS Dynamically Generating Barcode at runtime.

  Hello all. I need to build a barcode and stuff it in a image control at runtime in SRS. I have the code at it works perfect for webforms etc but not in the actual SRS report itself.

• Visual Studio Team System Team Explorer doesn't respect filesystem encryption settings

  I've got an encrypted folder (called 'Dev') on my laptop where the source is stored. When Team Explorer creates subfolders within the 'Dev' folder the folders are encrypted, but the files it creates are not. I've done this in the past with Source Safe and it worked fine, but it appears that when Team Explorer places a file on the file system it doesn't respect the folder settings for encryption. Even if I manually set the file to be encrypted, t ...Show All

• Windows Forms Problems sorting the DataGridView

  I am adding 20 columns to a DataGridView grid and setting the DataPropertyName so that it binds correctly. I am also setting the sorting to "automatic" for each column. When the grid first appears, the column headers appear. I can click on any column header and see the ascending/descending glif appear - but since there is no data in the grid - there is no sorting. However, as soon as I bind the grid to my data, my data appears in ...Show All

• Visual Basic Drawing images to a picture box?

  I'm trying to draw multiple images to one picture box (for a map editor) so that I can save the picture created as a file. I've been looking around but I can't find any help on it, so I'm posting here.
