Drawing On Picturebox Vs Drawing On Form?
Feb 18, 2012I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False
[Code]....
Exception Of Type 'System.ComponentModel.Win32Exception' Occurred In System.Drawing.dll
Oct 14, 2011I 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.

System.ArgumentException Was Unhandled (system.drawing.dll)?
May 6, 2008I 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.

View 3 RepliesSystem.drawing - .NET DrawRectangle For A Table?
Sep 30, 2010I 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?

Converting A String To System.Drawing.Font
May 8, 2010I'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.

View 1 RepliesFloodfill With A System.Drawing.Graphics() Object
Jun 7, 2011I need to make a basic drawing program in VB that can do three things:
"Draw" with a brush of some sort
Clear the screen
Perform a flood-fill (paintbucket action)
I decided to do the first two tasks first, and got them to work, but the third task completely eludes me. Every way I try seems to pile on exceptions, and every flood-fill algorithm I find seems to require a bitmap, rather than a Graphics() object. Is there any way to accomplish a flood-fill using a Graphics object, or must I restart the project using a bitmap?
