View 3 RepliesI always get an out of memory exception with my drawings...I read somewhere that I have to dispose my graphics to diminish the amount of memory used by the system.
I have the onPaint event and in there I call my functions with
Dim g as Graphics = e.Graphics
draw_all(g)
So in fact I have to dispose the e.Graphics every time he has to be repainted. Now my question how can I do that, because when I write before the draw_all function g.Dispose, that doesn't work, because he deletes the declaration of g and he doesn't know anymore what it is. If I dispose it after the draw_all function, he doesn't want to draw either.

View 2 RepliesI've problem with clearing all the drawings I've created in my PictureBox. In fact I've created animation which stops after certain time and remains on the screen. The animation is created/painted with collection of about 25 TextBoxes - input of a user. Now I've added a button which clears all that info in TextBoxes and also should clear PictureBox -ictureBox.Refresh(). The problem is when I add new info in 25 TextBoxes nothing appears in PictureBox and I can't start an animation. Wondering why...
View 11 RepliesI'm trying to write a program. This should be a simple task for most of you, but I have taken one class of programming back in High School so I'm kinda lost.
The program needs to do the following:
-Open AutoCAD File
-File=>Export=>PDF=>Save
-Close AutoCAD
If possible to select a whole folder full of these AutoCAD drawings and have the program run a loop until all the files in the folder have been exported into a pdf file.
my goal is to copy the content of a picturebox, to a System.Drawing.Bitmap object, called tempBMP. but i didnt even use it i just tried to declare it there's an error: Object reference not set to an instance of an object.

I am trying to develope a small graphics application in VB.NET. My startup form has a picture box with a background image loaded from a file. The user can click spots on the picture box and this draws some circles on it. On exit the coordinates for these spots are saved to a file.In my form load procedure I load the background image, the coordinates for the graphics(saved from the last time the program was run), and then call the drawing procedure.
The drawings appear for an instant and then dissappear. If you click the picture box the graphics re-appear.The form works fine once you do this.I guess the picture box is refreshed by the form load event and this is causing the drawings to be wiped.(I stalled the call to the drawing procedure by using a timer and this works but I am sure there is a proper way of fixing this)Is there a way of ensuring a form is fully loaded or making sure the drawing procedure occurs only when the form is fully loaded?

View 5 RepliesI have a blank form, and I've added a really simple Access database with two tables with two columns each. If I click and drag the name of one of the columns, and drop it on the form, I get a label and a textbox.
I was assuming that since the load procedure already had Me.WhateverTableAdapter.Fill in there, that when I pressed the green arrow to run the program, I'd be able to flip through the records in the column.
When I click "preview data", I do see the data is there, but when I run the program, it says 0 records and none load. Is there something else I have to do to be able to flip through the records in that one text box?
My scenario is i have a multiline textbox with multiple values e.g. below:

anothervalue = thisvalue

secondvalue = firstvalue
thisvalue = anothervalue

View 1 RepliesI would like to use a treeview control to display related data as Folders(Level0), Projects(Level1), Drawings(Level2). So far I don't have a problem reading data from a database, creating classes to hold the data and displaying the tree from the class data. I have created (3) contect menu strips, one for each level of the tree to perform various tasks. Each menu has an ADD option to either add a folder, add a project or add a drawing.My problem is as follows...After I add the node, in the correct location, I would like to have it set in the BeginEdit mode.
Dim oNode As New TreeNode
oNode = TreeView1.SelectedNode.Nodes.Add(sNextID, "New Project")
oNode.ImageIndex = 1
TreeView1.Refresh()
[code]....
After this code runs, the node.Text changes back to "New Project". As you can see, I added a few debug.print statements to try to see what is going on. It really blew my mind to see that the entire tree printed in the immediate window.I have already created a work around for this, but is isn't really the way I'd like to see the program run.

I have a rectangle with drawings inside it. I want to draw something else on top, but later restore the original insides without necessarily know what they were.
View 4 RepliesI have writen the code so you put the number of times you want to flip the "coin" and into a label the results show. I want it to show the % instead of the number of times that the side lands on.
This is what I have so far:

I have another problem regarding send message api cause i didnt find any good info on the net.
First of all Send message has:
Hwnd
Wmsg
Wparam
Lparam
What do those mean exactly ? Hwnd is the main window's hwnd or the child? Lparam and Wparam are pointers? How you get them from an external application? How you set Wmsg to send a string?
just curious if there was a way to make the text in a message box scroll across the message box

I have an application that uses SendMessage to send a list of numbers one at a time to a query window in the database we use. The problem is that when SendMessage fills the textbox, then clicks "Query" (hWndQuery) my application freezes up until the query is finished running, which sometimes can take up to 20 minutes depending on the query. Any way to force the program to be responsive after it 'clicks' the query button?
Below is my code - I commented where the program freezes (15 lines up from the bottom):Private Sub Query()
