Re: plz give me quick reply - Visual Basic Discussion Boards

If you hold a file open, then no-one else can use it. Folders, no.

I need a kind of password protection.

OK, then the answer is no. To do that, the best way I can see, is to replace the files and folders with files that are encrypted and are opened by double clicking on them via a custom file extension. There are commercial products that I believe do this, I don't see how else they could work.

Other than the method Christian mentioned, there's no way to do this without rewriting the NTFS File System. Youi cannot just assign a password to a file or folder like you see in the movies.

yes it is VB 6.0, i did'nt find anything related to my problem

OK sorry, I don't use VB6 and I am astounded that anyone still does. I hope you get your answer, but again, saying 'please get me quick reply' is rude, and won't help you.

What report?? Is this "report" generating this Excel sheet you're talking about??

Sections?? What sections?? You're going to have to clarify what you're asking about. I have no idea what you're using or trying to accomplish.

Hello,

I find the way to get the MyDocument path in VS2005, VB.NET like that :

My.Computer.FileSystem.SpecialDirectories.MyDocuments

But I didn't find the way to get the All Users Shared Document path.
(in french "C:\Documents and Settings\All Users\Documents")

The whole My thing is just a bit of syntactic sugar, from the docs it seems it is incomplete. Probably AllUsersApplicationData is your best bet, then go up one and back down to the one you want.

HI,
I HAVE A VB.NET APPLICATION, THERE IS A EXIT BUTTON IN MY FORM,ON CLICKING THAT I WILL SHOW A MESSAGE BOX , CHECK THE BELOW CODE
If MessageBox.Show("All the unsaved data will be lost! Are you sure you want to exit?", Me.Text, MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2, MessageBoxOptions.DefaultDesktopOnly) = DialogResult.Yes Then
--- SOME OPERATIONS --
END IF

THE PROBLEM is when i click YES OR NO, brings other open program into focus and hides this application

regards

winnie

Use the MessageBox overload that takes a window to be the parent window of the messageBox, so in C# you pass this, I guess you'd pass me in VB ?

I have built an installer using the Visual Studio 2005 setup project wizard. It installs correctly on Windows XP but fails on Windows Vista. As per my research i found that the failure on Windows Vista is caused by a custom action that fails with an access denied error. However, I am running the setup with admin privileges in Windows Vista. How can I fix my setup so it will work correctly on Windows Vista?

Error: "The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2869"

I tried to field a solution on the above problem and followed the below process

1-Download the sample script and extract the contents to the directory that contains the Visual Studio project you are working on
2-Open the project in Visual Studio 2005
3-Press F4 to display the Properties window
4-Click on the name of your setup/deployment project in the Solution Explorer
5-Click on the PostBuildEvent item in the Properties window to cause a button labeled "..." to appear
6-Click on the "..." button to display the Post-build Event Command Line dialog
7-Add the following command line in the Post-build event command line text box:
cscript.exe "$(ProjectDir)CustomAction_NoImpersonate.js" "$(BuiltOutputPath)"
8-Build your project in Visual Studio 2005

Now a new problem... the installer built now is installing in some system's with vista and showing same error for other system's in Vista.

Please help me find a solution...

Hello all, I'm using VB.NET 2003 Window Form to do some simple application. I found a problem on setting a global database connection string. How should I code it if this connection string might be change like from localhost to a Server or vice versa? This windom application may used MySQL or even MS SQL database for database as well. Anyone have this kind of solution here?

I read some article told me to put inside a module for this,but how can I do it?

This is my current testing connection which connected to my localhost MySQL database which is running perfectly in my development stage now.

Dim ConnString As String = "DRIVER={MySQL ODBC 3.51 Driver};SERVER=localhost;DATABASE=test;UID=root;PASSWORD=;Option=3;Port=3399;"<br />
   Dim Objconn As New OdbcConnection(ConnString)<br />
   Dim ObjComm As New OdbcCommand

Hope someone can give me a solution here. Thank you for reading.

I'm not sure what you're asking. IF you want to be able to change it later, put it in your app.config so a user can modify it, and have all code read it from there.

Sorry,I'm asking how to declare a connection string which is used for my window form application. Please correct me if my idea was wrong. Is that the app.config file is just used for web based like ASP.NET for connection? I'm using window form here. Please give me some example how to do this.

For detail explanation,my application allowed the user to connect to localhost database or a Server database by pointing to a different IP address. How can I do this??

No, you are thinking of the web.config. You have an app.config in your project which is turned into <yourappname>.config when it is built.

Then you read values in code with this sort of thing:

string value = ConfigurationManager.AppSettings["connectionString"];
