Look at using COM Interop to run a backup command. It's always easiest to record a macro in Access performing the required task, then convert to VBA, then look at the code and try to see how to achieve the same thing with the Access COM objects.

It's been that way for ages. As the top poster, I know that I can always exert at least equal influence to any 1 vote I disagree with, and almost always quite a bit more.

ASking here instead of the c++ forum. Windows Forms is plainly nothing to do with dlls, but it's actually the framework for windows apps in .NET

I have a infragistics Cardview enabled WinGrid with 2 column. First column is having the column headers and second column is having the value for the first column. I want to Preview the data in the grid. For that I've used UltraPrintPreviewDialog control (Infragistics Control). Preview is generating for the grid, But the column alignment is changing (It first displays all the data in the first column and then the data in the second column). I want preview with First column data and then second column data in each row. How to get like this..? Can any one help me pls....

Hi, I have a Windows Forms application that was working just fine. Then I moved 2 controls on the form a few pixels and changed the size of the form. After that I got the following errors:
error C2039: 'Dispose' : is not a member of 'System::ComponentModel::IContainer'
error C2039: 'CurrentThread' : is not a member of 'System::Threading::Thread'
and 2 more errors that were caused by the above. Does anyone have an idea how to fix this?

Obviously, you need to derive a class from TextBox, and add your property and whatever you want it to do, to the derived class.

pseudocode
public class NewTextBox :System.Windows.Forms.Textbox
{
public property NewProperty as string
{
get{;}
set{;}
}

Hi there,
Can you please help me with this problem.
I am trying to send my custom string to cacls command to set the permission on a file on my desktop. where the name is saved in a textfile, and loaded into a label named: SendThisTextToCaclsAsFilename
Here is a code snippet of what I have:
String^ customString = "/c echo y| cacls \"%HOMEDRIVE%\\Documents and Settings\\"%USERNAME%\\" + SendThisTextToCaclsAsFilename->Text + " /D Everyone";<br />
Process::Start("cmd.exe",customString);
Now the part that does not seem to work is this:
%USERNAME%\\" + SendThisTextToCaclsAsFilename->Text + " /D Everyone";
The /D Everyone is not part of the command, I think.
I can't see the error message that the command is showing, because obviously it only flashes when applying the permissions.
How can I make this work? 
Thank You in advance!!

Your command line would look like this:
cmd /c echo y| cacls "%HOMEDRIVE%\Documents and Settings"%USERNAME%\someText /D Everyone
There's a problem just before %USERNAME%. I think that line should look more like:
String^ customString = "/c echo y| cacls \"%HOMEDRIVE%\\Documents and Settings\\%USERNAME%\\" + SendThisTextToCaclsAsFilename->Text + "\" /D Everyone";

Great! Much Thanx, I'll give it a try!

How can I create a directory oon the current logged on user's desktop?
I have tried this with non luck!:
String^ FolderPath = "C:\\Documents and Settings\\%USERNAME%\\Desktop\\" + txtFolderName->Text; <br />
Directory::CreateDirectory(FolderPath);
And this:
String^ FolderPath = "C:\\Documents and Settings\ + Environment::UserName + \\Desktop\\" + txtFolderName->;Text;<br />
Directory::CreateDirectory(FolderPath);
Then I want to set deny permissions with .NET on that current logged on user directory I created above.
What namespaces is required for the .NET way? If possible!
Well this does'nt work:
String^ customString = "/c echo y| cacls \"%HOMEDRIVE%\\Documents and Settings\\%USERNAME%\\Desktop\\" + lblFolderName->Text + "\" /D Everyone";<br />
Process::Start("cmd.exe",customString);
And this also:
String^ customString = "/c echo y| cacls \"%HOMEDRIVE%\\Documents and Settings\\" + Environment::UserName + "\\Desktop\\" + lblFolderName->Text + "\" /D Everyone";<br />
Process::Start("cmd.exe",customString);
Much Thanx.

Why are you trying to deny permissions to Everyone on a folder that only the current logged in user can see anyway? The user wouldn't be able to see the contents of the folder, but there's nothing stopping that user from just going to the Security properties of it and resetting his own access permissions to it.
You're looking for the System.Security.AccessControl namespace (.NET 2.0 and above) to do this in your own code.

thanx, don't worry not trying to do it anymore. It was actually a silly thing to do. 
btw. I have a policy the restrict the user access to security permissions.

Does anyone know if this is even possible?
