when you create setup project first open the project you need to create setup for. then from file add new project and then other project types and setup project. give the name setup and select add to current solution (you should not create a new solution). when setup project is loaded, on filesystem editor right click application folder and select add -> project output and select primary project output.
this will detect dot net version and prerequisites automatically. now you won't have to select dot net manually

How visual studio will automatically add .net framework to detected dependencies folder in solution explorer.
I have - in the prerequisite - checked the download prerequisites from the same location as my application.
I can't add the exe into the active project.because it is the COM component , dll not the exe which gets added into the references
Now what i have to do in addition to these to make the visual studio automatically add .net framework to detected dependencies folder in solution explorer

so you are using a .net setup project for deploying a non .net project ?
i didn't understand. don't you have a sing exe or dll created in .net 2.0 in your project ?

have my program working but need to be able to search for files of multiple file types and search for multiple drives at the same time. Right now I can only search for one files type by typing the extension into a textbox. To search for the drive, i created a BrowseFolderDialog to search folder on a specific drive and the path is displayed in a textbox. So I have two question: Is there a way for me to search for multiple file types by typing the extensions in the textbox at the same time? Is there a way to search for more than one drive in a text box at one time?
Here is some code:
Private Sub GetDirectoryContents()
Dim FilePattern As String = "*." & TextBox2.Text.Trim
Dim sdir As String = TextBox1.Text.Trim
Dim dDir As New DirectoryInfo(sdir)
Dim fi As FileSystemInfo
For Each fi In dDir.GetFileSystemInfos(FilePattern)
ListBox1.Items.Add(fi.Name)
Next
End Sub
This is the class I created to search for the folders:
Dim MyBrowseFolder As New FolderBrowser()
Public Function ShowDialog(ByVal browseFolderTitle As String)
With MyBrowseFolder
.Style = FolderBrowserStyles.BrowseForComputer
.StartLocation = FolderBrowserFolder.MyComputer & .StartLocation = FolderBrowserFolder.MyDocuments
'Dialog box title
.Description = browseFolderTitle
.ShowDialog()
'Return the folder path.
ShowDialog = .DirectoryPath

let the users type multiple extensions to a textbox seperated by commas. create a thread to search a specific extension in your path and then run multiple instances of that thread with one extension in each thread. since you have the code convert the function you are using to a thread

How do I create a thread?
|
|
|
|
|
|
Is this correct because its still not working?
Dim MyThread As New System.Threading.Thread(AddressOf GetDirectoryContents)
MyThread.Start()
It may seem simple but I've never worked with threads before.

Threading is a advanced topic to understand in a few minuts. i thing you should search in MSDN and a overall knowledge about threads and threads in vb.net first. then write your program, thread functions are not like ordinary functions, and when handling you should be more cautious because you may end up in thread locks. but threads are good practice if you want your program run in a faster way (by deviding the work load to multiple threads so you can get all the work done simultaniously)
jds1207 wrote: Dim MyThread As New System.Threading.Thread(AddressOf GetDirectoryContents)
MyThread.Start()
there is no problem with your code, what is the error you are getting ?

Error: Cross-thread operation not valid: Control 'ListBox1' accessed from a thread other than the thread it was created on.
Right now, when I do the file search I type the file type in the textbox(txt) and the files with those types are displayed in a listbox. I want to change it so I can type in for example, txt, bmp, log into the textbox and display all of those file types in the listbox together. Is threading the only solution for this?
|
|

|

you can't directly use the objects you created in your application inside the thread,
you can do your multiple extension search without a thread too, but you will have to search one by one extensions,but this will consume some time

I want to build an application in Visual Basic, integrating GIS technology which includes maps, and databases. I am a student who cant afford all the nice packages please help.
|
|
|
|
|
I wrote a GIS application in C++ for my final year project at university. Technology has moved on a lot since then and it would be much easier nowadays. So go for it. You can download Visual Studio 2005 Express Edition for free and that's all that would be needed.
If you want a head start you could look for open source GIS projects. I'm sure I saw one on CodePlex a couple of months back - that might be useful for you.

my problem is,showing one arrow mark and plus sign in datagrid,if i click the plus sign means,the table come like tree node,then i click table means,then values are display from sql database with header name as new dataset.so i want to hide that arrow mark,plus sign and new dataset.how to hide these?i want only values display without that arrow mark,plus sign.
|
|
|
|
|
The Arrow you can get rid of by not showing the row headers, there is a property that you can set this, and the plus you can get rid of by only binding a DataTable to the datagrid, and not a DataSet. so instead of Datagrid1.datasource = dataset1 use datagrid1.datasource = dataset1.tables(0)

Setting permissions for new folders .NET 2.0 8mins ago
Hello,
I have seen the vb.net sample code on msdn for setting permissions for new folders (below), but still have some questions about it. I am writing a program that creates new folders, and sets permissions for the new folders. An Access database contains the permissions for each group. I have found very little information and examples for this subject. If anyone is familiar with security and the .NET 2.0 framework, I would greatly appreciate the help. Thank you for reading this message!

I take it you're talking about the The Foreign Exchange Market??
Help with what? Don't ask us to write code for you - that's just not going to happen. Why should we break a sweat so you can take credit for it?

|
|

It's been a very long time since I used that stuff, but, IIRC, no there isn't. You'd have to use a third party reporting library, like CrystalReports, to do this.
