VS 2008 : Call A PaintEventArgs Sub From Another Sub?
Oct 13, 2009I'd like to be able to call a Paint Sub that is framed like what you see immediately below from another sub but haven't been able to figure out how to do it yet. I'm working with option strict on.
Private Sub DisplayGraphics_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
End Sub
What would I put inside the parentheses to satisfy the arguments for the above sub DisplayGraphics_Paint().
DisplayGraphics_Paint(?, ?)
Perhaps I should modify the code for the Paint sub to do what I'm trying to do.
Alternatives To RichTextBox?
Sep 8, 2010For sometime now whenever I am in need of formatted text I have been using RichTextBox control and save data to RTF format. However lately I started using RTF editor control that allows you to insert images into rtf. And although this works, the file sizes grow immensely.I was wondering if nowadays there are any better alternatives (preferably available for free) that people can use in windows applications for viewing and editing documents.

Mar 31, 2011I'm thinking of porting my application from VB.net to the C# based MONO project, so it can run on both Windows and Mac. However, I am in need of a Mac-friendly alternative to WPF. It has to have very similar functionality. QML (by QT) is not a viable option, as it costs far too much money for us.
View 3 RepliesVS 2010 Alternatives For The Old Functions?
Sep 21, 2010When I try to code in VB2010, I usually unmark the reference to Microsoft.VisualBasic. Because I do not want to use the legacy functions of VB6. I want to complete walk in .Net path. And I have found some alternatives for the old VB6 functions. But the rest not. Where can I find the list of those methods or classes (alternatives for the VB6 functions) ?(For eg: when I tried to find the difference of 2 dates, I couldn't find any other alternatives. So, I came back and used the Microsoft.VisualBasic reference for using DateDiff())?
View 24 RepliesVS 2008 Drag And Drop And Alternatives?
May 20, 2011I'm working on a small utility program and found that I have a need to copy the contents of listboxes, textboxes and other control from one to another.
I just started playing around with Drag and Drop but it seems lacking a bit...for instance, if I wanted to drag the contents of a listview to a text box, it doesn't look like I can do that easily if at all.
Can you use a drag and drop to copy the contents of different control types easily?I thought about using the drag and drop method for notification of the intent to copy the contents and then I would code the copying.
The idea (although I know it will be slow but that is okay for this utility) to copy the source to a textbox and then from the textbox to the target. The content won't be that large and speed is not a concern at this point.
Here is my issue if I have to do it this way.
1 - How can I use the control names to do this?
2 - How do I get the target control name?
I figured I would create a function that I would pass the source control name and the target control name and based on type, perform the appropriate method of copying the data.
I haven't figured out a way to get the target control name. I can use activecontrol.name for the source.

View 3 Replies.net - Alternatives To SelectedIndexChanged That Don't Fire On Form Load?
Dec 24, 2009I'm developing in VB.NET with Visual Studio 2005.I have a ComboBox (myCombo) on a form that gets populated within the Load method.I also have handled myCombo.SelectedIndexChanged to change a label on the form.
Edit: The way I added the event handler was by double-clicking on the combo box on the designer. Skeleton code then came up in the code view.It looks like what's happening is when the form loads, SelectedIndexChanged gets fired each time an item is added to myCombo.This isn't what I want, but I'm thinking there's another event handler that only gets called when the user changes the selection.
Here's some code for what I have:
Private Sub myDlg_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' this is all I do with myCombo in this sub
list = GetListOfItemsToAdd()
[code].....
Update: The solution I used was to remove the Handles clause after the event generator, and add this before the "End Sub" above:
AddHandler myCombo.SelectedIndexChanged, AddressOf myCombo_SelectedIndexChanged
Alternatives For Accurately Representing Decimal Variables In C++
Mar 4, 2010I am currently working on a program that takes Visual Basic data in the form of a text file, and then stores this data in C++. Some of the data from Visual Basic is of the type Decimal. C++ has no built in type equivalent to decimal. I don't want to use double because there is a possible loss of significant figures if the numbers are large enough.One option is write my own decimal class.

View 2 RepliesRendering Graphics Efficiently - DirectX - Graphics Card And Use Of DirectDraw Or OpenGL
Sep 23, 2011We have a GIS application that has some performance issues. It creates and sends an image to a web browser. We start with a Bing Maps imager, add complex polygons (complete with transparent fill), save the finished image as a PNG, and send it to the browser.
The idea has come up that we could possibly install a graphics card and use DirectX or OpenGL to improve performance. I believe this would be the case even though we ultimately generate an image instead of sending the data the the screen. I believe our processes could still make use of the API and the hardware acceleration it provides. Our process is not unlike what CGI film makers do to render individuals frames of a film, though we simply render a single image and send it, as opposed to the hundreds of thousands of images needed for a single CGI film.
So my question is: would a powerful graphics card and use of DirectDraw or OpenGL provide us a worthwhile performance boost? It can take us 20-30 seconds to render a more complex map. Which is a long time to wait on a web page...

Interface And Graphics :: Passing Bitmaps & Graphics To Subroutines As Arguments
Jan 22, 2011I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

ok, i know the code is a little rough, but it should be good to give you an idea of what im trying to do, if not i will still explain.simply draw 2 lines one from left to right, another from top to bottom, intersecting through the tip of the mouse.ok, theres no problem there the lines draw perfectally the way i want them.... BUT! now heres the issue im having.i cant get rid the previous lines.i did a bit of good old "Google'ing" and ran across a few links that all pointed me to the ReDrawWindow API, so i tried (as you can see in the above code) but i just cant seem to get it worked out.
Interface And Graphics :: Draw On Tabpage's Graphics?
Jan 19, 2011So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.

View 15 Replies"Dim Temp As Graphics = E.graphics/
Oct 20, 2011My application is all centered around one form with lots of graphics drawings on it.All these drawings take place from within a paint event handler. However, the amount of code within that sub is becomming unwieldy.I have been trying to move sonme of it to another class and use the "dim temp as Graphics = e.graphics" construction to continue to draw graphics. However, I get all kind of argument exception runtime arreors when doing so (and I do not get these with the same graphics operations directly from the original paint event handler. I have also tried to pass on the original e argument, but with the same result.Is my conclusion that there is no solution to this so to continue with the unwieldy amount of code,correct, or am I mistaken somewhere. the "dim temp as graphics = e graphics" is recommended.

While I was trying to find out what the problem was, I realized that the processor load was about 50% and my graphics card was not used at all. So doesn't Visual Basic use the Graphics Accelerator to process graphics? What I made is not a real program. It's like an experiment (I tried to make an image flip). Here is the Code:
