• Windows Forms Multiple Instances of AxWebBrowser

  Hi, I have a csharp application, running multiple instances of AxWebBrowser at the same time. Each web browser requires the same cookie, set using InternetSetCookie. I used InternetSetCookie before I start navigating in each control. If one AxWebBrowser control is navigating, another control is not able to recognise the cookie. If I waited until the first control is complete navigating, then start navigating the second control, then it is able to recognise the cookie. Is this a known feature of the control Is there any way to get around it Thanks and Best Regards Thanks for your reply. That means I have to queue the navigations It will take too long, because I can have many instances of web br ...Show All

• SQL Server returning the number of rows from TOP PERCENT

  Greetings. I want to write a sql query that returns the number of rows from a query that uses top percent. For example, select top (7) percent object from objecttable It appears that @@rowcount will give the info but it does so as a separate column on each returned row. Any suggestions would be appreciated. Thanks. alan Thanks for the quick reply. I tried select top ( 7 ) percent objectid , count ( 1 ) over ( partition by 1 ) from bases order by state and got (objectid) (no column name) 16 85 19 85 23 85 85 85 38 85 34 85 I'm not sure what '85' represents. When I select and use @@rowcount I get '6' in each ...Show All

• SQL Server TRY... CATCH block does not behave as described or as expected...

  Below you have a piece of code that despite the TRY... CATCH block, has the following result: Msg 4860, Level 16, State 1, Line 4 Cannot bulk load. The file "C:\123.txt" does not exist. BEGIN TRY SELECT count(*) FROM OpenRowSet (BULK 'C:\123.txt', FORMATFILE = 'C:\123.txt.fmt') O END TRY BEGIN CATCH select 'catched' END CATCH select 'done' So why the code never falls into the CATCH block ---------------- Another misbehaviour of the TRY...

• Software Development for Windows Vista Finding the renderer filter in the Graph

  Hi, In my code I create a filter graph for rendering video files with audio components. I create the filters automatically using the RenderFile() function. I want to insert another filter just before the video renderer filter in order to process the video component of the file. Since I use the code for different kinds of video files I do not want to find the renderer filter using its name. For the files without audio, I enumerate the filters and I check for the output pins of the filters one by one. For the filter with no output pin I understand that its the video renderer filter, so I disconnect it and insert my OpenCV ProxyTrans filter. However, for the video files with audio I don't know how to find the video renderer f ...Show All

• Visual Basic My.Settings changes work, but are not reflected in Settings or app.config file

  Greetings: I'm using this code to record when a report was printed, and what month of records was covered. It works just as hoped it would. When I print a report, the date of printing, and what month the report is about is recorded, somewhere. However, when I look in the project Settings tab, and in the app.config file, the settings still show the test entries I put in on Day 1.

• Visual Studio Team System Emergency: Deleting Custom Work Item Type

  I played with custom workitem types and stuck in the middle. I created some workitem types that are irrelevant and they create errors everytime my team opens any workitem related interface or Team Explorer pane like "One form per Work Item"; we ignore the error and continue working; but it is annoying, undesired and some feature that VSTS must support as deleting a custom work item type if you are the TFS Administrator. I want to delete "the work item type" at all with no glue back. I deleted some unrecognized rows from SQL Database but still there they are. You are correct, we store the information in our database. Someone else might be able to help you with exact information or steps for deleting WIT - it could ...Show All

• Visual C# Any way to mix C++ templates and C#?

  I've been trying to write a small library that depends on C++ templates (C# generics are just too restrictive for my purposes), but I'd like to be able to access and use the final library from C#. I haven't been able to dig up much information about this, but my observations so far are that: 1: If I just define a class template in a managed C++ assembly, it's inaccessible from another assembly (This makes perfect sense given how and when C++ templates are instantiated. I'm actually surprised this is possible between two managed C++ assemblies) 2: If I specialize the class template, the resulting type is not accessible from a C# assembly either. That is, I do something like this in my C++ assembly: template <typename T ...Show All

• Smart Device Development Found conflicts between different versions of the same dependent assembly.

  Is there an easy way to determine which assembly or assemblies are conflicting When I double-click on the error message in the Error List panel, a message box pops up and says: One or more dependent assemblies have version conflicts. Do you want to fix these conflicts by adding binding redirect records in the app.config file Under what circumstances would I want to do that And what are the alternatives Use ildasm.exe to look at the manifests in your app and assemblies. The offending dependencies should be obvious if you don't have too many assemblies. If you have the option of recompiling the app (and/or assemblies) to have consistent references, do so. If you don't have any compatibility, dep ...Show All

• Visual Studio Tools for Office VSTO Seem Broken After SafeGuard Easy install

  I was forced to install a product by the name SafeGuard Easy (a whole disk encryption system) on my development PC at work and since them I have been unable to run my VSTO excel projects. SafeGuard Easy evidently has some kind of issue with Visual Studio 2005 as I was required to removed Visual Studio before SafeGuard would install. After SafeGuard was installed, I was able to reinstall Visual Studio, its service pack and VSTO 2005 SE but now excel addin projects do not launch. As far as I can tell, the addins for excel simply are not loading. The new() method in the code behind is not firing but there are no error messages either in excel or Visual Studio. 1) I've looked at the security settings for excel and they seem correct 2) I've lo ...Show All
