Re: how can use help.showpopup() to display non unicode text ( arabic text ) in Popup window in vb 2005 Dave Kreskowiak4-Jun-09 1:24 Dave Kreskowiak 4-Jun-09 1:24  No, I haven't. I don't even use the Help class. And from the OP's description, it didn't look like he was either. It looked more like a description of a problem with showing a normal window.

Re: How to use a an environment variable as argument to an program using shell command in VB.net 2005? Kschuler3-Jun-09 5:21 Kschuler 3-Jun-09 5:21  Sorry, I first wrote this: Shell("un.cmd" & x, AppWinStyle.NormalFocus, False) Then edited my comment to this (with a space after un.cmd): Shell("un.cmd " & x, AppWinStyle.NormalFocus, False) Try the one with the space. You were putting your variable in your code as a string, not the variable name. Re: How to use a an environment variable as argument to an program using shell command in VB.net 2005? Striker.dbz3-Jun-09 5:49 Striker.dbz 3-Jun-09 5:49  Thanks that worked but when my variable i.e text in the textbox1 contains spaces only first word is shown. this is what i want to actually do. @echo off 7zr a -mx9 "%1".7z "%1".ecm pause this is a batch program to create archives of any file give as first argument to it. now what i want to do is that i want do the same using vb so that i don't need an extra batch program. Can you please tell me how to doing by replacing the varibles %1 as variable x something like this dim x as string x = textbox1.text shell("7zr a -mx9 "x".7z "x".ecm") thanks.

Kschuler3-Jun-09 7:27 Kschuler 3-Jun-09 7:27  If your file name has spaces in it, I believe you have to surround the filename with double quotes. You'd want something like this: Shell("7zr a -mx9 " & """" & x & ".7z" & """" & " " & """" & x & ".ecm") Re: How to use a an environment variable as argument to an program using shell command in VB.net 2005?

Striker.dbz3-Jun-09 21:18 Striker.dbz 3-Jun-09 21:18  can you please explain how it was done. Thanks. Re: How to use a an environment variable as argument to an program using shell command in VB.net 2005? Kschuler4-Jun-09 2:43 Kschuler 4-Jun-09 2:43  Shell("7zr a -mx9 " & """" & x & ".7z" & """" & " " & """" & x & ".ecm") "7zr a -mx9 " is the call to your program, the space after the 9 is to get ready for the first parm. & """" concats a double quote & x concats your variable file name & ".7z" concats the extension & """" concats a double quote & " " concats a space to get ready for the next parm & """" concats a double quote & x concats your variable file name & ".ecm" concats the extension So...looks like I forgot to put the last quote in... you need one more of these: & """" for the last double quote. When your x variable is set to My File...this would be the output: 7zr a -mx9 "My File.7z" "My File.ecm" Re: How to use a an environment variable as argument to an program using shell command in VB.net 2005?

Maybe that WaitForExit method might be useful for something...

However, it returns a Process instance. If you call WaitForExit on this Process instance, your main application's thread will block until the process closes Between the idea And the reality Between the motion And the act Falls the Shadow Re: How to use a an environment variable as argument to an program using shell command in VB.net 2005?
