File System access seems to fail from VS 2005 add-in

[debnarayan]

Hi, I am working on a Visual Studio 2005 Add-In, which runs a Win-Form application to gather the data for it, and do other stuff. Later the add-in gathers certain info from the winform to open a solution file in the Visual Studio instance. Problem is[, rather are]: 1. There is a folder-browser dialog in the win-form, which is not displayed correctly. The folder list is not displayed at all. Looks like it cannot read the file-system 2. The win-form tries to save certain files to the system [to a folder pointed by user by the folder-dialog], which is failing [We have free-text area where we can type in the target folder name, if the browser does not work] This is happening on Vista machine [that's all that i have here] irrespective of UAC being turned on or off. Primary steps followed: 1. The winform app has to run by itself, and also from the add-in. So i hosted the win-form app in an AppDomain from the add-in. Also it has to be hosted in a separate thread, or else the form-closing signal [or that is what it seemed] was closing the Visual Studio window as well. 2. The win-form knows whether it is running from add-in or all by itself. Some string values are transferred from the add-in to the win-form and vice-versa via the AppDomain data storage. 3. As we are using Vista, the win-form as an independant application is made UAC aware, by the manifest file. So file system access is running great when i run the win-form independantly. Am i doing something wrong? Please guide...
