I found this code to rotate a picture online somewhere and made some changes and it works beautifully. My only problem is how much memory it uses. Does anyone see a way for it to use less memory?
Code:
Private Sub RotatePicture(ByRef bm_in As Bitmap, ByVal angle As Integer)
' Copy the output bitmap from the source image.

I've got Visual Studio 2010 and I am looking to clean up my code technique, since I've taught myself and now I'm taking classes.
I'm trying to use a For...Next Loop so that I can fill a text box with sequential numbers. For some reason, all I can get in the text box is the last number and I feel that at this point I'm probably overthinking it...
All I want is on the button push the text box shows:

Once I grasp this simple concept, I can move on to the actual challenge ahead of me, but I really want to know the proper way to handle this with out going all spaghetti code.
I used 4 seperate pictureboxes to load in each picture. Then I click the option to select X picture, which works. However, if I click another option, the Y picture doesn't load.I tried with:
pBox1.Visible = False
pBox2.Visible = False
pBox3.Visible = False

I have started with a small project in VB2008 Express which grew to a complex application. I have deployed the application recently discovering it is rather small, and the major issue is that code-generated controls (checkboxes, comboboxes, textboxes) are not displayed as during development. I have declared the code-generated controls in the declaration region, and there are about 250 controls. According to user selection some of the controls are added to a container panel. Now, I am concern that because I declare those as public (static?) variables, it uses much memory and causes the problem in the compiled application. Is that correct that static declared and code-generated controls uses much memory? How to avoid it ? I need the controls as public variables. Is it better to add all 250 controls on the form in designer mode, and use the property Visible (control.visible=True)?
View 1 RepliesWhen my form first loads, it runs at about 30k CPU, but after about 10 minutes of use, it goes up to (and stays at) about 70k CPU.
What ways can i optimize my code to allow the CPU usage to stay low, or how can i lower it during the running of the program.
My most concerned areas of the CPU are:
1. I have a web browser, and when a user types in a url and presses go or enter, the CPU jumps about 4k:
Private Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Go.Click
WebBrowser1.Navigate(OldURL.Text)
[Code]....
The second worry is when i open other forms, it boosts the CPU up aswell. the only code for this is:
Form.Show()
When a user make a program in visual basic, for example, can he/she copy and use some of the code samples provided in the MSDN Library? Is one totally free to use such code in one's programs, and even allowed to sell software containing such sample code, or does one have to massively modify it so that it resembles little of the original.
View 3 RepliesIs there a way to make the express version do a "clean build"?
Some of my project compilations have developed a problem which prevents debugging.
"The breakpoint that isn't working will display a message if highilighted with the mouse. The breakpoint will not currently be hit. No symbols have been loaded for this document."
The difference I've seen between the project folders for an app that will debug vs one that will not debug is that there is no ".pdb" file in the folder where the application to be debugged is running.Debug (F5) or "Build" no longer create this file.
Many of the discussion participants suggest deleting the "obj" and "bin" folders before compiling - on the assumption that this will "force" a "clean build" - is that supposed to be true? My express version has no "clean build" option, and deleting the obj and bin folders doesn't cuase them to be completely rebuilt.
Is "msbuild" the only way to force a complete build when you have the express version?

I'm developing a very simple program in VB2010 Express that will create folders based on entries in a remote database. I am fully aware that the minimum requirement to run the exe is the latest .net framework, however I have a few added resources to the file, and when I try to run the executable on another computer, it fails to run stating that the resources are missing.
How do i compile my VB code AND the resources together into a stand-alone executable that only requires the .net framework to be installed?I have already tried to google this issue, however every answer I find has nothing to do with my initial question..

View 3 RepliesWith a button click event, how do I make a picture box image property switch to a random image from the resources folder?
View 1 RepliesI made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?
