View 2 Repliesi was searching google for some kind solution and i found one, i tried to implement it in my code but it doesn't work. The problem is that after resizing white images they gets gray border.Here is the link of soloution i found:It says:
This problem is occuring because you are interpolating your image data to a new size, but along the edges there are no pixels to interpolate and .NET uses black pixels for these edges by default. To fix this you need to use an ImageAttributes class in your DrawImage call....

CODE 1: And this is my code WITH IMPLEMENTATION OF ImageAttributes:
Private Shared Function ResizeImageFile(ByVal imageFile As Byte(), ByVal targetSize As Integer) As Byte()
Using oldImage As System.Drawing.Image = System.Drawing.Image.FromStream(New MemoryStream(imageFile))
Dim newSize As Size = CalculateDimensions(oldImage.Size, targetSize)[code].......

View 1 RepliesI'm making a system where only the supervisors can use the Ctrl+Alt+Del to bring up the menu (Vista / Windows 7) or start taskmanager (XP)Since my application will not be running on anything less than XP I don't need to worry about 95, 98, ME, 2000, etc. I have this code so far (found on here and a little edit by me) but the Ctrl + Alt + Del doesn't get stopped like I thought it would.
Note to use this from within Visual Studio you might have to untick the box for "Enable the Visual Studio hosting proccess". In VS 2010 it is found in Solution Explorer > My Project > Debug > Enable Debugers > Enable the Visual Studio hosting proccess I've found several ways to stop taskmanager loading but not to stop the menu being displayed. This code is working except for my little problem with the Ctrl Alt Del menu and has been tested by me with VS 2010 .NET4 on Windows 7

View 1 RepliesI have a VB.net program that is developing a Word Document with a table of contents based on values in a SQL database. This works just fine. The issue I am running into is that I do not have control of the Office/Word environment. Some users have add-ins installed in their instance of MS Word. An example would be a PDF writer. Another example is a tool to put the document in a Document Management system. I am finding that some of these add-ins are slow to start and others do not shut down well. What I'd like to do is instantiate my MS Word application without running any installed add-ins.
