• Smart Device Development IP-address of ActiveSync computer

But i think that you can get the IP programmatically... Regards, Ahmed H. Waly ...Show All

• Windows Search Technologies How to search WDS on Vista using APIs in C++

  How do you programmatically search WDS on Vista using the APIs in C++ On WDS 2.x the procedure was:- 1. Create CLSID_SearchDesktop object 2. Get the IID_ISearchDesktop interface 3. Call ExecuteQuery on that interface with the query 4. Enumerate the recordset returned to get the results This works perfectly on WDS 2.x and also works on WDS 3.0 beta on XP. However on Vista it fails at the first step with the error class not registered. I was under the impression that the search in Vista was WDS 3.0, so why is the code not working when it works OK with WDS 3.0 under XP If there is another way to query under Vista what is it Can you provide an example Thanks Nick FYI String ...Show All

• Visual Basic Deploying an Addin in another computer

  Hi I created a Addin for CAD Tool called (solid works) in Vb2005 with .NET framework 2.0 Addin works fine when it runs in my computer. The addin is itself a dll file. When i copy the bin folder to another computer and add the addin to the CAD tool it raises the error with the message "one or more components missing". I have referred several libraries, some of them are COM libraries and some of them are .NET. It seems that there are few dependant dlls missing in the other computer. How do I deploy complete references with dependant dlls attached to them in another computer. Thanks in Advance Prash If you are referencing com libraries then xcopy deployment will not work withou ...Show All

• Visual C++ Optimization problems with Visual C++ 2005

  Hi, I have a huge problem with Visual C++ 2005. We recently moved from Visual C++ 6 to Visual C++ 2005 and since then we have had a number of performance issues. In one case, it is really extreme since the code generated is about 10 times slower than Visual C++ 6!! The code I am looking at right now is something like this: struct record { real a,b,c,d; } real a,b,c,d; for (int i=0;i<size;i++) {    record& elem = array ;    a += elem.a;    b+= elem.b;    c+= elem.c;    d+= elem.d; } I have tried to rewrite the code in different ways (using arrays instead of classes or variables on the stack and so on) but whatever I do i never get decent performance.

• SQL Server Programmatically Data Conversion component creation

  Hi there, I have created a package which simply imports data from a flat file to a SQL Server table. But I need to incorporate a data conversion component by which I may change the source-destination column mapping programmatically. So what I thought that I need to add a data conversion component into the dataflow task. After adding this component (I found its component id as {C3BF62C8-7C5C-4F85-83C3-E0B6F6BE267C} ) I have created a path which establishes the mapping between output columns of source component and the input columns of data conversion component. Now I am not sure how to establish the mapping between the data conversion component’s input column collection and output column collection. I am giving my code snippet her ...Show All

• Windows Search Technologies how to use the Foxit PDF Ifilter??? no preview

• SQL Server OPENROWSET Excel import failing on production machine

  Hi all. I have some sql like SELECT * FROM OPENROWSET('MSDASQL', 'Driver=Microsoft Excel Driver (*.xls);DBQ=C:\aaa.xls;', 'SELECT * FROM [Sheet1$]') Which works perfectly on our development machines (Windows 2003, SQL Server 2005 SP1). When I take it across to our production machines at the client (Windows 2003, SQL Server 2005 SP1) SQL kicks out the following error: Cannot initialise datasource object of OLEDB provider.

• Software Development for Windows Vista Biztalk error - messaging Engine failed to register ...

  Hi. I'm currently trying to start a Biztalk orchistation by calling a WebService as the starting point for the job. The orchistration is built and deployed succesfully, and all logical ports are connected to the acutal ports in the Biztal administration console. I've checked that the location of the ports are correct and exists. Each time we try to call the webservice to call, the eventlog produses this error message: The Messaging Engine failed to register the adapter for "SOAP" for the receive location "/startmovexwebservice/StartMovexWebService.asmx".

• SharePoint Products and Technologies sometimes i can break through code in vs2005 to debug a site

  I build my debug version, install it in GAC, then I reset iisreset .When i place a breakpoint I get the message: breakpoint will not currently be hit. no symbols have been loaded for this document Have u had this before. MKeeper, thanks for your input. It makes sense, but it doesn't clear it up ... at least not yet. Maybe I'm doing something wrong, but like the original author, even when it's not a site provisioning assembly, the breakpoints don't work unless I do as I explained. Then they do. In other words, if I install the debug version of an assembly with breakpoints into the GAC without doing anything else, the breakpoints don't work, even after all relevant assemblies have been loaded AND run.

• Visual Studio Express Editions Null reference exceptions
