• Internet Explorer Development accessing dhtml/dom within c# user control

  Hi, I have an embedded .NET user control in a web page, and I need to be able to navigate to a different page with the same browser when I click on a button in the control. How can I access IE's DOM from within the embedded control written in C#. I've been researching this issue for months, and have only found answers that involve .NET 2.0, which I can't use now and C++ which I don't know. Please help me out. Thanks I'd prefer use C++ to write an ActiveX.

  I've installed the last .NET 3.0 June CTP . My installation seems ok and I can create some personal cards using the selector (with its new GUI :)   Then I've tried to login to Kim Cameron's website and Microsoft Live Labs STS web site (the former one uses the HTML Object tag and the latter one the XHTML tag) Both trigger the selector... but only during 1 second and then it's closed.

• Visual Studio Team System More Continuous Integration problems

  I need to have my team builds which run on CI to build higher level applications if a lower level framework component is changed. For example, I have a framework Component and I have an application which has a binary reference to this framework component. If the framework component is changed, I would like this to be built. I would also like the application which has a binary reference (and any others which do) to be built. Is there a way which I can do this The dependency feature of TFS Integrator is interesting and something similar might end up in Automaton. TFS Integrator is a Windows Service only that triggers builds in the background, and it uses an XML based configuration that you have to setup ma ...Show All

• Visual Basic creating xdb file in access 2003

  Hi, I have a situation here; my client has a credit card processing application which captures credit card detail and some basic info. of a customer. all these details stores in a file which has an extension '.xdb', on opening this file in notepad it shows some special characters and stored data.

Now, my client wants that info. stored in ms-access application should be made available to credit card application. I originall ...Show All

• Software Development for Windows Vista Problem with IShellFolder::GetAttributesOf

  Hi, In vista RC1 I'm seeing a really odd problem with IShellFolder I have some fairly simple code which does something like: sfg = SFGAO_FOLDER|SFGAO_FILESYSTEM|SFGAO_BROWSABLE; pShellFolder->GetAttributesOf(1,&idl,&sfg); if(!(sfg&SFGAO_FILESYSTEM)) { continue; } What I'm observing is that in RC1 SFGAO_FILESYSYSTEM is only ever set for shared folders! On all other OS's it works as expected (and documented). I'm guessing this is an RC1 bug - where can I report this to make sure it's fixed for the release Tony This appears to still be happening - just tested on the final production Vsita build. I don't have time to do any further debugging until ...Show All

• Smart Device Development CAsyncSocket calls OnConnet(0) when the connection fails

  I am porting an MFC application to PocketPC that uses the CAsyncSocket class. I was able to make it connect successfully to the server. However I have the following problem: If the server is not reachable or the server is not started, the OnConnect(int nErrorCode) is called with nErrorCode==0 (like on a successful connection). This is a problem because my internal state thinks it's connected, but obviously it isn't. Has anyone experienced similar problems with the CAsyncSocket Is there some sample code available for a client CAsyncSocket application on the PocketPC That would help me to find the problem. The code works fine on the desktop version. Here are some more details and some code snippets: CTcpSocket is derived from CAsyncSocket , ...Show All
