Omar# Click once - customisation
hi all, I have created a windows forms app that uses the settings file to store the SQL Server name. I thought that this would enable me to customise the applcation for a number of sites without re-compiling for each one! the Settings File contains amongst others the name of the Local SQL Server. (always unique ) to facilitate easy updates, I have used the click-once methodology and hosted the deploy files locally at each Site on a server. The AutoUpdate works perfectly but the .config file( settings) is replaced each time with the standard settings file, the settings in this file are unique for each site! How do I deploy this application, while being able to have unique settings files for each site changing settings & ...Show All
AshleyT Show modal status dialog ?

Sheng Jiang &#40;&#33931;&#26207;&#41; Problems using custom controls in the designer [VC++]
I'm writing a windows forms application using Visual C++ express 2005. I created some custom control inheriting from usercontrol, and compiling them in a dll. This way I can add my controls in the toolbox, but if a form already contains one of these controls and I regenerate the project, the designer tells me that the instance of that control was not created. Usually if, after that, I run the project the designer gives no more errors. What is the problem Next, I often have to add method calls to my user controls in the InitializaComponent method, making the designer unable to show the form. How can I avoid this behavior Where is a good place to search info about interaction with the designer I have VC++ ...Show All
