If you mean doing it through code then one way is:
Dim textToSearch as string = "was"
Dim textToReplace as string = "gonnabe"
Dim textToSearchIn as string = yourRichTextBox.Text
Dim position as integer
position = textToSearchIn.IndexOf(textToSearch)
while position<>-1 ' If found
textToSearchIn = string.concat (textToSearchIn.Substring(0,position)), _
textToReplace, textToSearchIn.substring(position+textToSearch.length-1))
position = textToSearchIn.IndexOf(textToSearch)
end while
yourRichTextBox.Text = textToSearchIn
There may be other, and better, ways of accomplishing it but this should be also easy to understand the approach.

I did a query in Access and used that table as the datasource. Is there a way to do a SQL statement with multiple joins to an Access table in .Net? It always chokes when I try to include multiple tables. Thanks

i donot really understand, coz as i know you can databind to a table in the dataset and you just specify the dataset name and datatable name!

I'm trying to insert text and a graphic (jpg) into a word document. The user would select rows from their database and insert them into a word document.
My thought was to have my VB .net application execute MS Word. Upon opening a document the user selected, search for the text string [[INSERT]] (this could occur multiple times). Upon finding the text string, I would replace [[INSERT]] with text and graphic within the active document. The user would them save it. If there were other instances of the text string, the VB .net app would replace each successive [[INSERT]] with the next selected row from the database.
I'm not familar with macros in MS Word. I had look through MSDN and saw some VBA snipets, but not find and replace for Word.
Thanks for any help you could provide.

i'm writing a small app to change the windows mouse in VS'05, to change a key i do this:
Imports Microsoft.Win32
.
..
Dim key as RegistryKey = Registry.CurrentUser.OpenSubKey("Control Panel\\Cursors",True)
key.SetValue("Arrow","%SYSTEMROOT%\NewCursor.cur",RegistryValueKind.ExpandString)
i would like to do this same thing in VS'03, but it does not facilitate the last parameter where i use the RegistryValueKind class (or enum, whatever it is).
does anyone know the vb03 equivalent to the line:
key.SetValue("Arrow","%SYSTEMROOT%\NewCursor.cur",RegistryValueKind.ExpandString) ?

From the MSDN Gospel:
Note: When setting a value, the way in which the value being passed is stored in the registry is interpreted. There is no way to control whether the information being passed is stored as an sz, or an expanded_sz string, and therefore, all string values are interpreted as standard sz values.
If the .SetValue method call will not set the value properly, then you'll have to P/Invoke the Registry API calls yourself to do it correctly. Check out http://www.pinvoke.net[^] for more information.

well it would seem that the the site you gave me only lists API functions that retrieve the datatype, not change it. am i wrong?

Is there any tutorial regarding skinning an application? because I found an OCX file that allows you to skin your application, it's called VB Skinner. I wonder if I can create my own skin. Thanx

Sure - just handle the key press event.
Private Sub KeyUp(ByVal sender As Object, ByVal ea As KeyEventArgs) Handles TextBox1.KeyUp
If ea.KeyCode = Keys.Return Then
Dim tb as TextBox = sender
MyHTTPFunction(tb.Text)
End If
End Sub

Oh, OK. You import the web service into your project, right click on the project and choose add web reference. When you do this, you get a class auto generated, and you can just call it's methods to call the web service.

I am new to VB and have some experience with C++. I am trying to use some code that I have copied out of an article from this site for creating GPS applications. ( http://www.codeproject.com/vb/net/WritingGPSApplications1.asp ) I am having trouble figuring out out how to use these classes. The one that updates the system clock with GPS time fits my needs exactly. My OOP experience is limited but I have been reviewing my books. I think that I have to read data from the comm port and put it into the class to start the process but I am not sure how to get that done. I am using Visual Studio .NET. I would appreciate any help that might get me headed in the right direction. Thank you.

I'm not sure how this is a OOP question. There are articles on reading the serial and parallel ports on this site. If that's not what you need, please provide more info.

I am trying to use the code from the "How to Write Your Own GPS Application" article but I don't know how to make it work. Assuming that I know nothing about VB.NET, how do I get that code (which looks like it is a class) to work? The application I am writing needs to update the system clock with GPS time, nothing else.

I don't know the article in question, surely if you run the demo and read the article, you'll see it working ? If not, I'd suggest asking the article author.

To answer your question, I am here to get some assistance while learning something new. I would like to thank you for welcoming me so warmly. If this forum is not for assistance and sharing ideas then what is it for?
The article I read has no demo and I have had no response to my request for assistance from the author. I have been hoping that I could get some pointers on how to get the code that is available to work for me as it does not work alone. I believe that I need to call to it with an object but I am not sure how to do that. The article I am writing about is at the link below.

OK - I'm sorry to be blunt. What I really meant was, are you really saying you have no idea how to use VB.NET ? I was advocating that surely you'd do a bit of reading and play with a few demo projects so you had enough of an idea to be able to make sense of any help that we offer you.

If you follow the link to WritingGPSApplications2, from the first article page, there is VB and C# code which includes a form, so I presume that it gives examples of how to call the code. It looks to me like the code in the first article is meant to be cumulative ( i.e. you only need the last file ). I'd have a look at that second article and see if it's got anything more useful in it.

Ok, I will give it a try. Thank you.

For the past few weeks I have been reading a book or two and working some examples. I am getting somewhat familiar with VB.NET and I am excited to learn more about it. I am having trouble getting through some of the more specialized things though, and it has been a long since I have taken any programming classes, or written any code for that matter. I will try your advice and see if I can get it going.

I am trying to send ATAPI commands to a cdrom in VB.Net. While researching this it seems to me the VB is not the best at this. I am sure their is a way though. Can anyone steer me in the right direction? I read something on calling the Windows API to do some hardware speaking, but it said that that is being Phased out with VB.Net.
I am able to send these commands through 2 other test programs that we use.
Thanks!
Ken

Ken,
Using the Windows API in vb.net is still supported with interop.
Anyway, if can you tell me what sort of ata commands you wish to send to the cdrom, maybe I can help out.

Thanks for the update!
I send a few similar requests to the drive with these other programs. For instance, I send an inquiry command - 12 00 00 00 FF 00 00 00 00 00 00 00. I am able to get the device type and model returned with that. I also do a 'Get Configuration' Command and 2 other commands that run a self test and then read the stored results.
I really apreciate your help!
Ken

Ken,
To access the drive at that level you'll have to use a win32 function called
DeviceIoControl from the Lib kernel32.dll under interop.
Do you have any source for the "other programs" you are talking about, that could give us a starting point?
Reading the device type and model number is not so hard, but coding the self test could get tricky. (IO control is not something I do very often)
If not, I'll have to dig back through some code I did last year on testing smart ide drives under ata control, so it may take me some time to work on this.
