• François Paradis Send output to stdout from gui app...possible?

  I have a simple vb.net gui application (an alternative file requester in a form) that I would like to run from the command line. It executes fine, but I find that I cannot send any output (a string representing the file selected) to the command line upon completion. It appears that "console.writeline" doesn't actually write to the console Any suggestions as to how to send info back to the console window upon completion Keep in mind that this is a gui app (not straight console). that doesnt work ReneeC, I also tried that I instantiated that streams and received valid streams although, the second was a null stream. There is abother approach. You begin with a console task and add f ...Show All

• William Lowers Minimizing Process Start Up - CPU usage and Start UP Time

  We have a one process which is started multiple times from a .NET Visual Basic console "exe" (i.e. many of these can be running simultaneously). Each process does its job and exits. We are continually starting these processes using the process object. Is there any way to minimize the "start up" time and CPU usage each time a process is started Best Regards - Dan Golden Is the process being started a .Net application - if so then you may be able to Ngen it to save a little bit of time.

• Ghassan Rashed Running a batch file

  Is there a special way of running a batch file I have tried process.start but it is not working. The batch file works when I double click it but not when I try to run it through my program. Thank you, Troy L The following will work without any clicking at all and will start xyz.bat with no arguments. Process.start("xyz.bat","") If your requiring a double click - then its probably something in your code or the bat file as process.start should not require any user involvement. I guess the current directory is not set, simply by executing the batch in the directory of your executable. Put e.g. this at the end of your batch: dir . pause Then you will see, wh ...Show All

• Wahl04 Responding To A User Clicking The Red X In Upper Right Corner

  Using VS05 Visual Basic - when a user closes a program by the red x in the upper right hand corner, is there a way to respond to that the same way as if they had properly used File, Exit Does the X raise an event I have not been able to figure this out yet. I don't want to disable the X, just respond to it. Thanks for your help. Bob The reason is this is a telephony application and File|Exit waits for all calls to finish before exiting the program. The Red X simply hangs up on everyone as the program closes. Thanks! Bob Hi, you could hook into FormClosing event and check the CloseReason parameter to see why it's being closed. If it's value is "UserClosing", the user either clicked the Red X, pres ...Show All

• altamash Program to execute on one machine only

  Hello, My problem is that I want to deploy my program onto a 'thumb drive' and sell it that way and I need the program to only run off that drive. It is a small program that can easily be copied and run by anyone so I thought that if I could somehow 'lock' it to the small USB drive then that would solve my problem. Because some games require a CD to be in a drive before they will run I figured that that would be something that I could do, my problem is finding any help in how that might be accomplished. Can anyone point me in the right direction Thank you very much Bill Langston That's going to be hard to do. CD-Roms are generally copy-protected by playing weird games with the disk formatting.

• laserbeam listview to richtext drag / drop problem

  I have a vb.net app coded up with drag drop from a listview to a richtext box. Here is the relevant code: using listitem "hp41exec", e.Data.GetData(DataFormats.Text).ToString = "hp41exec", as one would expect. It's difficult to use breakpoints, since it tends to drop text into my source code :( Stepping thru it though, ListViewItemDrag fires twice and ListViewDragDrop fires only once. I suspect what is going on is the richtext object is doing its own DragDrop. Does that make sense If you want to look at the project, I can email it to you. That does seem strange - when you put a breakpoint on the drop handler, can you see what exactly is happening on the second drop S ...Show All
