How can I draw a frame or groupbox or panel whose style effect is 'Raised' (See attachment). In most of the cases when we set the Frame or Panel borderstyle to 3D, the style effect is 'Sunken'. But I want it to be 'Raised'. This is possible if you add the reference- Microsoft Forms 2.0 Object Library, choose Microsoft Forms 2.0 Frame from 'Choose Toolbox Items' and set its SpecialEffect property to Raised. But that is a COM component and I want it to be done through core .Net framework components.

View 1 RepliesI'm planning on using the Smart Device Framework 2.3 to use the signature control panel in a Windows Mobile 5 application using the compact framework 3.5.
The control has the option to save the signature as either a byte array of points, or as a bitmap. Now seeing as I want to store the signature in a sql compact database, I guess the byte array is going to be better. The trouble is, I'm not sure how to render that in a full WinForms application after I've transferred it back to the desktop.
I need to show the signature on a report, so it would need to be an image I could link/embed into the report.
Im using this code
Private Sub Form1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter

In the IterationForm, I have values being calculated and displayed as and when an operation is being performed.
In the panel it shows only the blank form. I need to have those values displayed as well.
I have tried using MDI parent with my menustrip1, same thing, that is the form being displayed without the values.
I want to add a MDI parent form to a panel on a base form, the problem is that i must set the toplevel = false when add the parent form to the base form, but if i set its toplevel to false i can't set isMDIParent parameter to true. how can i fix this conflict?

View 1 RepliesI'm trying to draw a 400x400 px image to a 400x400 form that I made. What I'm doing is:
Graphics.DrawImage Method (Image, 0, 0, 400, 400) 0, 0, 400, 400, ...
But when I run the form, the image seems to stretch slightly upon the y-axis, the x-axis seems to be working correctly.
This was what I was doing before (stretching the old smaller images to fit the size)
... (Image, 0, 0, 264, 231) 0, 0, 400, 400, ...
or something like that. Now that I'm trying to do it the correct way, I can't seem to get it to work properly.
Edit: I wonder if using a simpler verson of Graphics.DrawImage would work?

View 3 RepliesI want to move cursor with visual basic and it seems I found way how to do that. It is possible even click with Visual Basic whereever on screen. But I cannot check out where on the screen the click was done and so I want to draw two short crossing lines on that point as marker where Visual Basic clicked on screen. If it is possible to move cursor to that position and show it then it is as good as drawing marker.

View 7 RepliesI am basically teaching my students about OO programming and want them to be able to see the outcomes to methods visually. I want to draw shapes on a form but cant for the life of me get it to work - no errors but no actual shapes are being drawn. So I have created a method called drawFace which is run when a new instance of the object is created. This method has the following code in it
Form1.CreateGraphics.DrawEllipse(Pens.Black, 100, 100, 100, 50)
It doesn't cause any errors, but it doesn't seem to do anything. Also tried adding a picture box to the stage and ammending the code as such
Form1.PictureBox1.CreateGraphics.DrawEllipse(Pens.Black, 100, 100, 100, 50)
But still no joy.
