• .NET Development passing a safe Array as an out parameter to a .net component

  I have a .Net component that passes a stringArray to a client program via an out parameter. This works fine from a .net client and I have successfully passed a SafeArray from MFC to a .net component as an [in] parameter. What seems to evade me is returning returning an array of BSTR from a .net component via the CCW as an [out] parameter, back to this MFC client Can anyone help regards Hi Robert, This call seems wrong to me: SafeArrayGetElement( pSC , &bound[2] , XX); 1) you must pass a BSTR reference to be filled: SafeArrayGetElement( pSC , &bound[2] , (void*)&XX); 2) the third parame ...Show All

• .NET Development CPU problems in a .NET COM+ application

  Hi,  I have a COM+ application developed in C# which is based on Microsoft Exchange Store Events. The application is using asynchronous save event to extract each e-mail fields and base on these fields add a "special tag" to the e-mail. The COM+ application is extracting the fields and sends them to another application which runs on another computer. This application analyzes the content of the fields and is returning the "special tag" for the e-mail. The "special tag" is saved by the COM+ application in the e-mail. I have tested this application on some test servers and it is running fine, but when I installed on a real life serv ...Show All

• Visual FoxPro DBclick

  the dbclick event can't be effect after i wrote program in mousedown event in grid control.how can i fix it thank you A button would work, either on the form or in an adjacent column. The other way is to workaround it, but it's a bit of a pain.  You might add a timer: On the first mouse down, start the timer.  On the second mouse down check to see if the timer has been started.  If it has stop the timer and do the double click code. If the timer expires the single click code runs. The problem with this is that there is a small lag before the single click code runs and that is often unacceptable. The other way would be ...Show All

• .NET Development What happens underneath the BulkCopy Object of ADO.NET 2.0

  Hi , Does someknow how does new Bulkcopy work in ADO.NET 2.0 What happens underneath because of which the performance gets better with BulkCopy Regards, Anjana There are a number of reasons why bulk-copy is faster. Here is a summary: No per-row statement execution. When you do multiple inserts without bulk-copy, each insert is a statement in itself (regardless of whether it's batched together with other statements). With bulk-copy, we don't incur the cost of executing a statement for each row, the whole copy operation is a single thing. No multiple network round-trips. Once the bulk-insert operation is setup, w ...Show All

  I have been charged with gathering all incoming faxes, converting them to PDF files and thru keywords (Names Departments etc.) sending them to specific personel using Active Directory. I have a program that will convert to PDF, but I need to know how to search and distribute with (I hope) VB. I am brand new to this so any help would be greatly appreciated.
