First, install the IDE. Then, read the MSDN that came with it. Then buy a book/download some of the samples and play with them. If at any point you get stuck, ask specific questions here.

I have a search page with 3 textboxes. I want to do a search on any text that may be in the text boxes. Let's say we have box1, box2, and box3. I want to do a search as follows:
If box1 <> "" Then
do this...
ElseIf box2 <>"" then
do this..
ElseIF box3 <> "" Then
Do this...
Else
do this ...
Does anyone know how to do this using CASE statement?

Hi there,
Instead of using the two else statement in the if block i would rather use one as follows
If box1= "" and box2="" and box3="" then
SQL= no query or no search
else
' this indicates at least one box has the a text
'then SQl query can be as follows
SQl = "Select * from Table where ColumnA=box1.text or ColumnA=box2.text or columnA=box3.text
end if
I hope this helps

Hi All,
Point function of Form object returns color of the pixel at a
partcular location on the form.
I tried to use this function in a project of Graphics.
I found that the behaviour of the function was strange.
Sometimes, the function returned a color value upon clicking
a pixel on form.
Other times, it simply falied to return anything.
It just kept returning -1 eventhought the color of the pixel was red.
The same code worked on other PCs while on still others it failed.
Can anyone explain why Point function behaves like this ?
I need a quick reply.
Thank you.

 Hi!
I wanna send a value to a field on a site, i m using AxWebBroeser Control in vb.net, i 've displayed the page in the control..how can i do this...plz help me
Thanks!

You need to obtain a reference to the control to which you want to send the value and then set it. The trick is to get the Name of the control to obtain the reference. For this you can inspect the source code for the target page.
This is some sample code that loads the Google web site in an AxWebBrowser control, sets the search value to "axwebbrowser" and auto-presses the Search button. I based this example on one I found on the web somehere a while ago.
Assuming the web browser control is named web1, navigate to the web site in your Sub Main() (or whatever).
web1.Navigate("http://www.google.com")
In web1's DocumentComplete event:
Private Sub web1_DocumentComplete(ByVal sender As Object, ByVal e As AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent) Handles web1.DocumentComplete
' Get the web document
Dim myDoc As mshtml.HTMLDocument
myDoc = DirectCast(web1.Document, mshtml.HTMLDocument)
' Get the reference to the search text input box.
' The name of this control is "q" which I found from
' inspecting the page's source code.
Dim otxtSearchBox As mshtml.HTMLInputElement
otxtSearchBox = DirectCast(myDoc.all.item("q", 0), mshtml.HTMLInputElement)
' Set the search value to "axwebbrowser"
otxtSearchBox.value = "axwebbrowser"
' Get a reference to the search button and simulate
' pressing it by calling the control's Click() event.
Dim btnSearch As mshtml.HTMLInputElement
btnSearch = DirectCast(myDoc.all.item("btnG", 0), mshtml.HTMLInputElement)
btnSearch.click()
' The web control will now update and presnet the search results.
End Sub

Hi,
I have just completed making my user control for the VB.NET studio,which I have built as a DLL file. Now, when it comes to setting up the deployment project, I am unable to determine the appropriate location to install the DLL file so that another VB.NET programmer can easily access this file and make use of the control.
Thanks in advance!

drobj = selcom.ExecuteReader<br />
If drobj.Read Then<br />
TextBox1.Text = drobj.GetValue(0)<br />
TextBox2.Text = drobj.GetValue(1)<br />

Ok, so you DID get an error! What was it? Provide more information and thou shall receive quality help...
Anyway I can see one obvious coding problem with this line:
Deema Jack wrote: selcom.CommandText = "select* from PatientsTable where(Patient_Name= " & TextBox2.Text & ")"
It should read:
selcom.CommandText = "select * from PatientsTable where Patient_Name = '" & TextBox2.Text & "'"
Note the use of single quotes surrounding the TextBox2.Text value otherwise SQL Server will most likely throw out the query. All strings should be quoted in queries. Additionally there should be no parentheses where you have used them in the WHERE clause.

Thanks Steve,thank you very much. Do you know,I tried the statement which you wrote above before you tell me ,but I got an error,I think my error was in the quotes,but when I copyed yours it's done, Thank you again. I want to say that I'm a begginer student in Vb.net in an institute for computer ,there,they're just teaching us the basics of the vb.net language.
So, would you tell me about the try-catch-finally statements, what is the correct method in writing them, I don't know more about it,and could you tell me the name of a helping book in the structured exception handling.
with thanks,
deema

Deema, you are welcome. Glad I could help you.
The best first place to find more information on structured exception handling would be a Google search. Also try searching through The Code Project archives for articles on the subject. The VB.NET online help is also useful.
I could not provide a tutorial on the subject in this forum - it is not the place for it and I simply don't have the time to do so but I will answer any specific questions if you get stuck at any stage as will many other contributors.

I just made a BIG, STUPID mistake. I deleted all the .resx and .aspx.vb files on my machine through Dreamwaver Test Server view! It will kill me to re-write all the code  .
I have recently re-built the project into .DLL file before deleting those files. Is there anybody know how to decompile .DLL file to get source code back????
I also find there is a tempporary folder "_vti_cnf" under my wwwroot/project folder. In this folder, there are .aspx.vb and .RESX files. However, .aspx.vb file only contains the information like :
vti_encoding:SR|utf8-nl
vti_timelastmodified:TR| 17 Oct 2005 16:58:30 -0000
vti_extenderversion:SR| 4.0.2.8912
Could anybody help me out???
Thank you in advance!!!!!

Vicky,
Stupid question, but are the files in the recycle bin or do you do what I do and delete bypassing the r/c bin?
If you have not already done so, I suggest downloading a file undelete utility from the web - there are several out there, try FreeUndelete for a start but of course download it on another machine or to a different drive etc so you won't overwrite any deleted files.
Programs do exist to extract resources etc from DLLs but I cannot help in that regard. They certainly won't be able to recover your source code.
...Steve

Assuming you compiled to the DLL to msil and not all the way to native then Reflector works reasonably well - you will have to massage the code a lot to restore it to it's original state, but it is a lot faster than rewriting it ...

I would like to know how to code a class library that will show the number of sentences in any document or file that is open. The number has to show in a label.
Thanks

los_coronado wrote: I would like to know how to code a class library that will show the number of sentences in any document or file that is open. The number has to show in a label.
This sounds like a homework/project/assignmnent question to me.
Where do you want to start? Do you have any idea how to approach this task? What you have asked for is rather vague and open-ended. What part are you particularly having trouble understanding? How to read the file, parsing the file's contents into sentences, creating the label (and where the label is to appear), is this a standalone program, part of a Word addin component, or what?
Be more specific with your questiosn and we can provide more useful help to you. We will not however, write the code for you. For that see www.rentacoder.com

Sorry, this is the first time I post a question here.
Ok, here is what I need to do. I have a text box and labels to get the number of characters, words, sentences, paragraphas in it. I want to get the number of sentences, but I keep getting one when there is no "." in it.
Here is the code
Dim pstrStringString
Dim mintWords As Integer
Dim pstrSentences() As String = Split(pstrString, "." -1)
For s As Integer = 0 To pstrSenteces.Length - 1
mintWords +=1
I have to show the number of sentences in a label when a button is click. Why do I keep gettin one even tough there is no "."
