Converting A String To System.Drawing.Font
May 8, 2010
I'm saving the font of a label to a text file, and when I open the text file with my program, I want the label to have the same font that is listed within the text file. Now, the only problem I am having is that when I try to write the code for opening the text file, I can't set the font property of the label to a string. Label1.Font=[Font: Name=Microsoft Sans Serif, Size=9.75, Units=3, GdiCharSet=0, GdiVerticalFont= False]Here is what the code to open the text file and set the font of the label looks like:[code]The problem for the code happens at line 6. The error is: "Value of type 'String' cannot be converted to 'System.Drawing.Font'"ing each part of the font in the text file(i.e. Writing Font.Name and Font.Size properties in separate lines and then setting the label's font properties to each line accordingly), but I still get hit with the same error.

I am making a web browser using geckofx. I have put the favicon in a picture box but I have changed my mind and now I want it as the form's icon. The code for the favicon is:[code...]
The favicon works fine in the picture box but i think it will look better as an icon. If i change the line Me.PictureBox1.Image = favicon to Form1.icon = favicon I get the error Value of type 'System.Drawing.Image' cannot be converted to 'System.Drawing.Icon'. How can I get this to work?

I have a program that creates a Treeview from information procured through an ODBC query and dumped into a dataset. I have three such queries set up via radial buttons as well as a refresh button that triggers whatever radial button is active at the time it's clicked. The purpose of this program is to allow drag-and-drop of selected nodes, ending with a post to the database that officially makes that change of assignment to the new node.

I created an application in VS2005 that draws text with a custom font and color. The images look great from my XP machine. But from another machine running Windows Vista, the graphics are messed up. It seems that the transparencies inherit the default black background so there's this gray'ish/black haze around the text...

I made a program with Visual Basic Express 2008. I got this error message when I try to close my program after running it. (PS: It is a simple code that can login into Microsoft SQL Server)The error message shows the error was caused by the "system.drawing" (Parameter is not valid). Also, I have been trying the code in VBA (Excel). When I tried to close Excel after running my code, I got the same problem (Microsoft Excel has encountered a problem and need to be closed.....) and the error report shows the error was caused by "system.drawing" as well.

I want to draw a table in my print output using the System.Drawing.Printing's Graphics object. I'm trying to use the DrawRectangle to draw my table cells. This requires drawing several rectangles in a row. It should be pretty easy, right? Well it appears that DrawRectangle four parameters are x, y, width, and height. However x and y are integers while width and height are singles. My rectangles are overlapping because the next cell in a row cannot base its x position on the width of the previous rectangle. In other words, the x position and width are different data types and don't use the same scale. How can I calculate the x position of the next cell based on the width of the previous cell?
