OK, but at which line does it fail, what is the error displayed (if any) and what are the parameters to the function/sub that failed?
Have you run this in debug mode (single step) and inspected the parameters to the calls line-by-line? If so, what did you find?

Huh? Are you using VB6, VB.NET or something else?
You cannot compile a VB program with a C compiler and visa versa.
The error you have shown here is a compiler (i.e. make file) error and not a runtime error from the program.

this is not a compiler error , because when i run same thing through my vb project, whose build condition is debug mode it run make file very well , but it fail through exe

You are not listening to what I'm saying. Have a look back over my replies and provide the requested information otherwise I cannot help you.
The error message is not from your compiled program - it is from the MAKE process. I respectfully suggest that what you think you are running as your compiled EXE is not really your compiled EXE.
Check, double check, then double check again.

You haven't by chance named your compiled program something like "MAKE.EXE" or some variant?
Possibly a program of the same name already exists on your target PC and is being selected for execution instead of your own?

Right... if you'd said this in the first place then we'd have solved it a bit quicker. Moral of the story is: give as much _accurate_ information in the first instance so we don't waste time.
Also I can see that in your code you provided (thanks) not all of it is included so some referenced functions are not available to me for diagnosis.
The problem most likely arises because the path you are giving the program is possibly not fully qualified or that the current working directory of the program is not what it is expecting. When you run in debug mode the application's path is basically the project folder on your C: (or D: or E: whatever..) drive.
Why don't you add some message boxes to your code to display the command being executed at runtime so that you can see whether or not the makefile command is constructed properly (i.e. it has the correct parameters).
Try running that command manually from a command prompt - do the CHDIR() etc... as the program would on your development machine and see what the differences are if any.

hi i am really sorry for not sending the proper info, there is no way to attachment, at least i don't know, this is very first time i am on forum.
now,
when i manually use command prompt , go in that perticular directory where my make file reside with the c files to be compiled everything work properly.
now my vb project (with build condition as debug) is at "d:", that time also i am able to go at c:\test folder & able to run make file properly.
here while i use my installed program it doen't work properly.
So while to build setup do i have to take different precaution if yes then plz help me.
the code i have sent you. do it work at your ent or not.
i must thank you , for your trials, to slove my problem

hi i tried as you say i am watching my current working directory,
curdir(), shows me the same directory (path ) which i entered in textbox1.
but still i am unable to run the make , it gives me the same error.
so it means the problem is in run time
can you guess, what is problem
waiting for reply

The message you posted isn't a VB Runtime error. It has something to do with your MAKE process that you're launching. You would probably be doing yourself a favor if in your command line to launch the MAKE process, you directed the output to a file to log everything that is going on. You can append > C:\makeoutput.txt to your command line.

Need a good Email Validator function...Help me out!

Dear Dave,
What exactly im looking for is a function in VB .NET to validate an email address inserted into a textbox in windows application forms.
I surfed the web and I found the following code :
Function ValidEmail(ByVal strCheck As String) As Boolean
Dim bCK As Boolean
Dim strDomainType As String
Dim strDomainName As String
Const sInvalidChars As String = "!#$%^&*()=+{}[]|\;:'/?>,< "
Dim i As Integer
bCK = Not InStr(1, strCheck, Chr(34)) > 0 'Check to see if there is a double quote
If Not bCK Then GoTo ExitFunction
bCK = Not InStr(1, strCheck, "..") > 0 'Check to see if there are consecutive dots
If Not bCK Then GoTo ExitFunction
' Check for invalid characters.
If Len(strCheck) > Len(sInvalidChars) Then
For i = 1 To Len(sInvalidChars)
If InStr(strCheck, Mid(sInvalidChars, i, 1)) > 0 Then
bCK = False
GoTo ExitFunction
End If
Next
Else
For i = 1 To Len(strCheck)
If InStr(sInvalidChars, Mid(strCheck, i, 1)) > 0 Then
bCK = False
GoTo ExitFunction
End If
Next
End If
If InStr(1, strCheck, "@") > 1 Then 'Check for an @ symbol
bCK = Len(Left(strCheck, InStr(1, strCheck, "@") - 1)) > 0
Else
bCK = False
End If
If Not bCK Then GoTo ExitFunction
strCheck = Right(strCheck, Len(strCheck) - InStr(1, strCheck, "@"))
bCK = Not InStr(1, strCheck, "@") > 0 'Check to see if there are too many @'s
If Not bCK Then GoTo ExitFunction
strDomainType = Right(strCheck, Len(strCheck) - InStr(1, strCheck, "."))
bCK = Len(strDomainType) > 0 And InStr(1, strCheck, ".") < Len(strCheck)
If Not bCK Then GoTo ExitFunction
strCheck = Left(strCheck, Len(strCheck) - Len(strDomainType) - 1)
Do Until InStr(1, strCheck, ".") <= 1
If Len(strCheck) >= InStr(1, strCheck, ".") Then
strCheck = Left(strCheck, Len(strCheck) - (InStr(1, strCheck, ".") - 1))
Else
bCK = False
GoTo ExitFunction
End If
Loop
If strCheck = "." Or Len(strCheck) = 0 Then bCK = False
ExitFunction:
ValidEmail = bCK
End Function
But I when I copy the code in my application LEFT and RIGHT are shown as SYNTAX ERROR,
do I need to IMPORT sth in order to make them recognized?
Regards,
AmirK1

You tried to use old VB6, or VBScript code. Left and Right don't exist in the .NET Framework. Trash this code and try something from a more specific Google[^] search, like "vb.net email validation code"

This is a school project. I have to use at least one array and two text files to store information in. The problem I have is that once the app closes, all the information in the array is set 0. Can the information in the array persist on exit? And if not, can the information from the text files that are created fill the array when the app opens?
More background info...
This is a project that requires someone to update inventory information for 10 records in an array. Stock# is the same in both text files and I am totaling one field in one of the text files which updates the array by using the text box on the form.
Thank you,
Larry

An array only lasts for the lifetime of the program. If you want to persist its data when the program ends, you'll need to write it out to a file.
Same thing when the program starts - the array is empty and you'll need to read the data in from the file and populate your array.

Thanks...I think that is where I am confused. I am not sure how to read each line of the txt file to populate the array when the app opens. I am guessing I need to use a For...Next loop but how does I know what line I am on and how to pull each item/column of data and seperate it from the other columns. The array has 5 columns and the text files have 2 columns and 5 columns with one common column.
Is there a function to know how to grab each column per row in the text file...
Lastly this is a school project as I mentioned. Why would you use an array over a database like Access or SQL where it would seem reading and writing data would make more sense.
Thanks in advance!
Larry
