• markovuksanovic Testing Multiple Instances of Winform application

  Hi, Wanted to know what are the testing tools available to test the multiple instances of a win form application. Here is what i need to do: I have a win form application which uses some external toolkit. the toolkit has limitations in terms of the instances creation. I wish to automate the stress testing of the win form application using some tool so that i can find out the threshold limit of the external toolkit.. Basically i want to do a load generation on the win form app by spawning multiple instances of the application with the necessary user clicks scripted in. Are there any tools that come along with the VS 2005 which can help me or i have to resort to LoadRunner or any other tool. Any pointers would be appreciated. Thanks Paritos ...Show All

  Dear friends i have basic doubt that is can we add ListItem's to ListBox (or) is ListItem's are only for ListView any suggetions Thanks Ranadheer It is only for ListView.

• JackMit Taskbar item flashing

  I am using VS2005 in a VB.Net 2 type application, and my main form has several buttons and functions which cause other forms within the same application to open. If the main form does not have focus (either out in another application, another form within the same application is open, etc) and information on the main form is updated, how can I get the item in the taskbar that represents my main form to "flash" for a period of time I am presuming I can take the same concept of the "solution" for this and apply it to the other forms within the applcation. Example, main form open, another form opens to display information, and remains open. The user then selects the main form, the second one gets updated information, an ...Show All

• thedewd System.AccessViolationException in System.Drawing.SafeNativeMethods.Gdip.GdipDrawLineI

  I really do not know what to do about this. Often, when I run Forms programs with Visual Studio the application crashes with an exception like this "AccessViolationException". I never exerienced any problems with other standard applications like e.g. Word, Excel, Outlook, only self written programs in C# seem to suffer from this. Most of these applications then contain either something like a ToolStrip or a DataGrid which then after an exception like this are only represented by a white rectangle with a red X. The controls itself are standard out of the box. I ran the Microsoft Memory Diagnostic today, but it did not find anything wrong with my memory. Does anybody has an idea what may cause this exception See the end ...Show All

• Tim Cools is the right place to ask question about installshield

  With Install Shield, if I want to include a dll and that dll is pat of a merger module (redistributable) it includes the whole merge module in the installation project and it doesn t allow me to include only the dll. Do you know if it s possible to include only a certain dll with an exe project and not the whole merge module that includes that dll. Thanks As Ahmed said, no, this isn't a right forum to ask that. Please visit official InstallShield forums . Thank you. since installsheild is not a Microsoft product, it would be the wrong place to post and the best place would be over at their forums. If you are using the setup & deployment project within VS2003/2005 (Pro/Std editions) then yes this is the cor ...Show All

• enric vives Particular question about a Setup and Deployment project.

  Hello everybody! I'm quite new to Visual Studio and I'm having a hard time finding out this. I have a working project right now, which installs perfectly. It installs some application files and some help files. What I need now is the help files, instead of being inside the .msi package, to be outside, just in a folder. For example, in the installation folder I have the setup.exe, the .msi package, and the Help folder. So, when I run the setup, I need it to perform as usual, with the only difference that the help files are copied from that folder and not from inside the .msi file. The destination folder of the help files is not changed, so the shortcuts must remain as they are now. In other words, I need the installer to take the files of t ...Show All
