have you tried setting the focus of the control you want in the load event of the form?

or simply set you tab indexes correctly and it should automatically be the first control that gets focus

-> You can easily set the TabIndex property of Textbox to 0 for focusing.
-> At Form OnLoad event, set textbox.focus().

Hi All,

I have a question that I can't answer, I hope you guys will help me =)

I have a program in which user selects a source directory and a target directory and the files in the source directory are processed and copied into the target directory. All is fine until this:

I created directories manually (for test purposes), I mean not inside the code but Right Click-->New-->New Folder =)

When the process is done, files are OK. This means they can be deleted, moved, renamed. But the directories stay locked. I cannot rename, move, delete the directories. D'Oh! | :doh:

So, why does this happen and how can I correct it?

Thanks Smile | :)

Edit: Oh, by the way I forgot to mention I used DirectoryInfo and FileInfo.

Well, I guess you're right. My bad, my bad. Blush | :O

DirectoryInfo dir = new DirectoryInfo(srcDirectory);

foreach (FileInfo fil in dir.GetFiles("*.jpg"))
{
    imagesJPEG.Add(Bitmap.FromFile(fil.FullName));
    fileNames.Add(fil.Name);
    imageCount++;
}
foreach (FileInfo fil in dir.GetFiles("*.tiff"))
{
    imagesTIFF.Add(Bitmap.FromFile(fil.FullName));
    fileNames.Add(fil.Name);
    imageCount++;
}
foreach (FileInfo fil in dir.GetFiles("*.png"))
{
        imagesPNG.Add(Bitmap.FromFile(fil.FullName));
        fileNames.Add(fil.Name);
        imageCount++;
}

This is the only code which has direct access to directories. All other functions just use a string for the destination folder and doesn't have anything to do with folders =)

If you are working with images, don't forget to dispose them. Otherwise they will stay locked.

Thanks for the reply

They are disposed right after they are processed but I will take a look at that just to make sure.

But, as I said, files which are copied into the target directory are not locked. Only the target directory stays locked.

Hi,

use Image.FromStream() instead of Image.FromFile(); that way they don't get locked at all.

So, you say this can keep only the folder locked, while the files created are not.

I'll give it a try and let you know.

Thanks =)

I didn't say a thing about folders.
However when a file is locked, so is the entire path to it.

Well, actually that's the point which confuses me. =)

Files are ok. They can be deleted, renamed, moved, whatever you want. But only the folder is not. You cannot do these to the folder and when you try you face that "File's in use" kinda error =)

But as I said just the folder not the entire path. Smile | :)

Maybe I'm a sinner and God is punishing me this way Poke tongue | ;-P

Seriously, I wonder what I'm doing wrong. Smile | :)

Hi,

if your folder is locked when your app runs,, and not when it doesn't run, then there is something wrong in your app.

if your folder is locked all the time, then either some other program is locking it (try closing every app), or it got a read-only flag set.

if you need help, provide very specific symptoms.

I guess you're right about the details I've provided, my mistake Smile | :)

And the folder is locked all the time after I've created it (manually created by the way, not created by the application).

Anyways I'll have to figure out a solution no matter what.

So thanks for the effort, everyone Smile | :)

Bitmap.FromFile() sucks, it keep lock the file until you dispose that Bitmap instance. Use Bitmap.FromStream() instead.

Replacing an executable file, programatically.....

Hi guys,

I've written a simple C# console application is VS.NET 2005 and now I want that as soon as the user clicks on the exe file, the location of the exe file, no matter wherever it is, is shifted to 'D:/Folder/'. It is noteworthy, that I dont want replication, just replacement of the original exe file from its source location, to that location programmed. Therefore, can anyone help me with that little piece of code, using which I can replace my console app. from its current location to another location programatically allocated on the system?

Your help will be appreciated,
Rajdeep.NET D'Oh! | :doh:
