• Visual Basic strange behaviour

  Hi guys, I am definitely a newbiew to .Net, and am having a problem that I cannot seem to get around. I have a single Windows form app that loads several (probably about 10) datatables into a dataset. The dataset is defined as a public. Eventually the data is summarized into a datatable that is displayed into a datagrid. At first I could not get the double-click to work, and eventually tried to add a context menu control to capture a right click. Once I got things wired up, when the menuitem click event fired, I wanted to create a dataview from one of the datatables in the dataset and filter accordingly. To my surprise, the dataset variable has a value of nothing while in the click event. I then figured out how to capture a double ...Show All

• .NET Development Remote Debugging of ASP.Net 2003 application

  I have been assigned to make a research on remote debugging using Visual Studio 2003. The scenario is that I have a web server over which an asp.net site is hosted, I have to perform the developments, debugging from another remote machine within same domain. Initially web server can contain the source code (.cs files etc) but does not have an IDE installed on server, the IDE is installed on the remote machine.

• Visual C++ The specified module could not be found. (Exception from HRESULT: 0x8007007E)?

  I've just experienced this runtime exception for the first time. I'm trying to instantiate a managed c++ dll object from a c# executable, and it raises this exception. Im running WinXP, and using Visual Studio I first read several groups, and came across an excellent article by Grimes on this topic. http://www.ddj.com/documents/q=1/ddj0604f/0604f.html .

• Internet Explorer Development Selectively Removing IE History

  Hi all. Is there a way to effectively traverse the URL history and selectively delete entries (our pages) from it. We have a web based application that uses a client side ActiveX control, so we have full access to the Windows API. Any help or direction would be greatly appreciated. -BG I was able to put together a prototype that successfully calls the DeleteUrl method from IUrlHisotyrStg. After this is done I can confirm that the selected URL's are gone if I enumerate thru the history again. So far so good, but... If I pull up IE, the URLs are still listed in the history and they're also still in the Temporary Internet Files directory. So I'm really not sure what I've accomplished by doing ...Show All

• Visual C++ Presenting a C++ library (.lib) for use in C# project

  I have a collection of C++ programs and the C++ libraries they use. The libraries currently compile to a .lib format. Changing the project property to use a .dll results in multiple reference errors. Without having to go through the entire collection of source files, is there a way to create any kind of project in a .NET language that would provide a "wrapper" for the existing .lib files so that they could be used in that environment.

• SQL Server Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

  I am receiving the following message when connecting via query analzyer to SQL server using windows authentication.(error 18452). I have a login created with the sys admin server role on the server. When I connect using SQL authentication it works. I added myself to the local admin group on the server, this allows it to work. The same situation is seen with another user. I am using windows 2000 sp4 server and SQL 2000 SP3, connecting from NT4. I get the same issue if I use TCP or named pipes. We have been using SQL security but are moving to windows authentication - but this issue is stopping us. I have checked and upgraded my version of MDAC to match the server version 2.7 (sp1) Any help would be much appreciated. Thanks ...Show All
