I am using the following code.
But there is occuring an error
Failure sending mail
Dim mail As New Net.Mail.MailMessage()
'set the addresses
mail.From = New Net.Mail.MailAddress("pankajgarg10@yahoo.co.in")
mail.To.Add("pankajgarg10@yahoo.co.in")
'set the content
mail.Subject = "This is an email"
mail.Body = "this is a sample body"
'send the message
Dim smtp As New Net.Mail.SmtpClient("This is the I.P address of my machine")
smtp.Send(mail)

What's the exact error message?
This will only work if your machine has an SMTP server installed on it AND is allowed to mail to another mail server on the Internet.

have a look at the Showdialog function of a Form and its Parameters......
If you are calling form2 from form1 call like this
Dim myFrm as frm1<br />
myFrm=New myFrm<br />
myFrm.Showdialog(Me)
it will make frm1 as Parent/Owner of frm2

You can't do it the way you decribed. Windows does not support MDIChild forms having MDIChild's themselves. A form can NOT be both an MDIParent and MDIChild at the same time.

plz tell me to display/call a value in a label/textbox accesed from database of sql 2005 express edition using data reader or any thing else (not grid veiw method)
if possible send me example

Your question makes no sense. What do you want to do ? It sounds like if you could word it better, you could just type it in to google and find dozens of hits. You want to combine a data reader, a textbox and a database ? Which bits don't you know how to do ? Once you have the data, you can just read it and assign it to the Text property.

You're joking, right??
You want use to give you the entire source code to a VOIP project so you just turn in something that's not your work? It's bloody obvious you don't even know what you're talking about. Why should we help you cheat in a class you're not qualified to pass?

Does anyone know how to open Windows Picture and Fax Viewer using Shell Command in vb6?
I tried the following code, but it does nothing:
Shell "rundll32.exe C:\WINXP\System32\shimgvw.dll, ImageView_Fullscreen " & Chr(34) & (<filepath>) & Chr(34), vbMaximizedFocus
Please help!

I can't get it to work either. It would appear that that functionality isn't exported anymore. But, it's probably possible to do it using its COM interface. Try adding a Reference to the "Preview 1 Type Library". Once you add the reference, you can open the Object Browser and see the methods and properties the Preview class exports.

I've tried to save a bitmap image but failed. Please help me!!!
Thanks!

What do you mean you have failed. Are you getting an error? Is the output not what you expect? What exactly are you trying to do with this code. Please explain so we might help, because I don't think this code is what you want. From what I can tell you are creating a bitmap from an image on your harddrive. You are then creating another bitmap from a different image on your harddrive. The loop attempts to copy all the pixels from the first image over the second image.
|
|
|
|
|
bmpOut.Save(fOutName, System.Drawing.Imaging.ImageFormat.Bmp)
The error is found on this command statement. I dont think it is wrong but I cant even figure out what's happened

You didn't answer the question. What has failed ? Did you get an error at runtime ? At compile time ? Did you end up with a file you can't open ? A file that doesn't contain what you expected ?

Creating a bitmap using dim bmp as new bitmap("somefile") will lock the file. In your code you created the bitmap from fOutName. You are also trying to write the new bitmap to that same file. My guess is whatever error your getting is due to the fact that the file is locked. You can get around this by using a stream instead.
Dim fs As New IO.FileStream(fOutName, IO.FileMode.Open)
Dim bmpOut As New Bitmap(fs)
fs.Dispose()
Hope that helps.

Dim bmpOut As New Bitmap(fs)
For x = 0 To bmpIn.Height - 1
For y = 0 To bmpIn.Width - 1
bmpOut.SetPixel(x, y, bmpIn.GetPixel(x, y))
Next
Next
bmpOut.Save(fOutName, System.Drawing.Imaging.ImageFormat.Bmp)
fs.Dispose()
I've tried but failed with the error statement "Parameter is not vail" which can be describled in detail that:

First try moving fs.dispose up a few lines. If the stream hasn't been disposed the file will still be locked I believe. You did give write permission, but even so this will ensure you have full access to the file. Once you've created the bitmap you can dispose of the stream so just do it after the bitmap gets made. Try that first. You may still get an error from the sounds of it. I got that same error for completly unknown reasons. As far as I could tell it was a glitch. I closed VS 2005 and re-opened it. I then used the exact same code and it worked. Also just to re-create the code that I used perfectly don't use FileAccess.write. If you move the dispose code up and remove FileAccess.write the code should work. If it doesn't you may be experiencing the same glitch I came across. In that case I'm not sure what to tell you. To double check try creating a new project and use just the code to create the bitmap from the stream. Try the code and if it works move that code to your current project. If it then fails we know there is a problem.
