I am trying to use a background image for one of my programs and I get this error when I try to make the BackColor Transparent. It allows me to use the Background image I want but I get this error when I try to change the BackColor to Transparent. A Box pops up that says "Property value is not valid.", then when I click Details, it says "Control does not support transparent background colors."
View 9 RepliesI have been looking in a lot web site and forums trying to find the way to make my picturebox background transparent or catch whatever I drew on top of a transparent panel, let's explain it.
Case 1-) I trying to make an app, where the user can load onto the winform a word document(I have part this ready), then I put on top of the control where the doc. is loaded a transparent panel(this part is ready too) and the user can sing (on top the panel) then I need to get the user's draw(sing) and print it in the document.
Every time that I try to do it always I get everything that is within the panel area, then I just want the user's sing.
case 2-) I tried to use a picturebox then it works perfect, I can get just the user's sing and print it back in the document, but the problem is, I can't put a picturebox on top of the control where the doc. is loaded because then I can't see the doc.
If anybody wants to see the code to make the panel transparent, or catch whatever you draw on top the pictureBox.

I'm having a problem using transparent colors within the graphics object of the System.Drawing.Printing.PrintDocument class. If I create two overlapping rectangles with the alpha channel of the color set to some value of transparency, the output colors are the same as setting the alpha component to not transparent, so the rectangle that is drawn second is on top of the first rectangle, completely covering that portion of the rectangle. I've tried to get transparencies to work, but I can't. The closest I've come is to set[code]...
View 9 RepliesOne last hangup with an application and I've tried like heck to research this but no luck.When I do a button click on my open file, it brings up a sub with all the open file code same for my save file and everything works perfectly.If, the open file dialog is on the screen and you should click either cancel or close I get the following argument exception unhandled, (and I've pasted all the details).It throws the exception at the very first line where textbox1 gets it's backcolor(txc(0)) is the variable in my.settings
