I'm trying to copy a file, using System.Copy. The destination, if it exists, should be overwritten. I had been using a single line of code for about a month, without problems : IO.File.Copy(SourceFile, DestFile, True)But problems started about a week ago, when I started more advanced checks. Partially locked files fail to copy, and the destination gets deleted. Locked files, on the other hand, work correctly: they just trigger a file in use exception.So I added this line before launching the copy:Using TestForAccess As New IO.FileStream(SourceFile, IO.FileMode.Open, IO. FileAccess. Read, IO.FileShare.None) : End Using..This was supposed to launch an error if the file was in use. But it is to sensitive. Some files (such as thunderbird's abook.mab) trigger an error in this added code, whereas they copied fine before (and you can copy them in explorer).My question basically is: How do I tell the system: copy source to destination if possible; if not, don't break destination?

View 2 RepliesI am using VB 2008 & drawimage function to copy image A to Image B. My problem is image A has many different colored patches on it and I only want to copy the ones that have a certain RGB value. I was going to set the masking color to the RGB value but remembered that defines the color to ignore - Im interested in the opposite.
I know I could loop through all the pixels and check its color, but its way slow and Im hoping theres something better?

I've a program that draw an image in a picturebox with DrawImage. This image, a ball (.png transparent), every second is overwritten by another ball of different color. After 3-5 second the edge of the ball becomes bad, because of overwriting.
I tried to clean the background with a FillRectangle before any overwrite, but i need to preserve the windows form background. How can i do that?
Well currently im programming a game in Visual Basic and I have it to the point where it draws a map on the form, it loads maps to different areas when you walk on the map, and I am doing so by using Graphics. DrawImage which redraws the map on the screen with the character in the new position. It was working quickly and smoothly until now.
I added some more sprites and now it starts to lag badly then it will throw a Out of Memory exception and it will display a big red x across the form. I watched the memory now as i move the character one spot on the forum and the memory increases 100mb's each time. It wasn't doing this before which is weird. I managed to fix the out of memory error using GC.GarbageCollect but I read that this is bad, also the character still lags across the forum. I really didn't want to release the source code until I was finished but seeing as I need help quickly because this is for a project I am working on for Thursday (End of semester Programming 2 Junior year of high school) I don't have many options.
In my user control's paint handler I iterate over a collection of predefined Bitmap objects and draw them to the client area thusly:
C# version:
private void Control_Paint(object sender, PaintEventArgs e) {
Graphics g = e.Graphics;
foreach (BitmapObj bmpObj in _bitmapObjCollection) {
g.DrawImageUnscaled(bmpObj.Bitmap, bmpObj.Location);
[Code] .....
The code works fine but starts to bog down when a dozen or so objects are added to the collection. My question is: Is there a way to speed this up? Would it be possible to use the Win32 bitblt function to replace DrawImageUnscaled? And if so how?
Graphics.DrawImage loses resolution

In VB6 the Scaling version of the BITBLT api worked fine, however in .NET's Drawimage version of it works okay, until a different destination size is specified.url...The red is from the next tile on the source image. and the bottom is missing one row of pixels.I have also screened this, and counted that the left side isn't properly doubled and the very first column of pixels is in 1x1 squares instead of 2x2 like the rest of the image.I don't get why it's obtaining outside the range I set, so here is my code incase it helps, note that you'll need to define a blocks array:[code]
View 3 RepliesIn my program I allow the user to copy a file from one folder to another. If the file already exists in the target folder I want it to be overwritten.
All that works just fine - I'm not asking how to copy files.
But here's an example
Source file is:-
\SomeMachinesomeFolderfile.xyz
Target is:-
P:file.xyz
This might at first look like two separate files but in this case P: is mapped to \SomeMachinesomeFolder so the source and the target are actually the same file and the file copy will obviously fail.
Of course I want it to fail but my problem is that the windows generic error message seen by the user is not very helpful. It says something simple like "... can't be copied because it's busy". If the user isn't very bright he doesn't realize he's selected the same file both as source and target and he doesn't understand why it's busy.
What I want to do is detect in advance that the source and the target are the same file and display a more meaningful message to the user and not even bother trying to copy.
So, is there a way to detect that
\SomeMachinesomeFolderfile.xyz
and
P:file.xyz
are actually the same file?
This is my first post to these forums so forgive me for any etiquette I may be disregarding.I am creating a custom control that has a TabControl on it. The user will then double click or right click the TabControl to display a ContextMenuStrip asking if they would like to add a new image (or tab) to the project. After they select the image file, I create a new tab, add that to the TabControl, and then I want to create a PictureBox that I draw on in a particular way depending on space available and several other factors.
Where I am having the issue is in drawing the image to the PictureBox, it is only displaying the BackColor and none of the DrawImage work. It is important to note that because of what I am doing it will not suffice to set the PicBox.Image = ImageFile or PicBox.BackgroundImage = ImageFile. I need to select tiles from the image file and then draw them into the PictureBox in a particular way, which changes if the control resizes. Also, I am using a PictureBox because the final image within it can potentially be larger than the containing tab page, and therefore I want the TabPage to generate an AutoScroll bar. If there is another way to do this, please let me know.
Below is a very simple example of what I have currently. What I suspect to be happening is that the PictureBox's Paint event is firing after I do my DrawImage work and basically overriding what I did, but I hope I am wrong.OpenAddTilesetForm() simply displays a form for the user to select which image to use, and the properties pertaining to it.
