• Visual C++ Printing to memory

  I need to put the data which is sent to a printer into a memory buffer. It is quite easy to print to a file using the printing functions of the platform SDK. It's enough to specify the file name in the DOCINFO structure before using it with the StartDoc function. Therefore, I can print to disk file and read this file copying the data to my buffer. That's what I do until now. But, I wish to save time and disk accesses and I do not need to have a temp file on my disk. Does anybody know the way to send directly the printer data to the memory Take a look at http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=850480&SiteID=1 OTP Thanks, Ayman Shoukry VC++ Team ...Show All

• SQL Server Unable to run a report after deployed in a remote server

  Hi All, I encountered the following error after I deployed a report to a remote server. The deployment process was successful, however, when I try to run the reports from the remote report server, It gives me an error message saying: An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'SessionOLAP'. (rsErrorOpeningConnection) For more information about this error navigate to the report server on the local server machine, or enable remote errors On the other hand, I deployed this report on the local machine and it is running perfect.

• Game Technologies: DirectX, XNA, XACT, etc. 3D Stereo support

  1. Will D3D10 feature native driver/runtime support for stereoscopic 3D, including application control over stero separation and convergence similar to Nvidia's IStereoAPI 2. Will DirectX SDK include guidelines for stereo compatibility, like those in NVIDIA GPU Programming Guide (Chapter 9. Stereoscopic Game Development) 1. Stereo support is not part of the Direct3D 10 API. But nVidia could provide support in the same way as they do it at the moment. 2. As it is not supported there will be no documentation. ...Show All

• SQL Server HTML String Rendering in a Report

  We have a "Comment" field that is saved as a HTML string to the DB. This field needs to be pulled into a report as rendered HTML. I know this has been hashed out before, but has anybody found a good solution in the past couple of months We are thinking about storing two versions of the Comment in the DB: one with HTML, one as simple text. Has anybody found this an acceptable solution I know it flies in the face of good DB design, but it seems the quickest, easiest solution... Any word if this will be fixed in the next major release of SSRS Can we expect this release any time soon Thanks for looking, Smith Hi Luis, Do you mean you can display HTML in SQL Report Services using ...Show All

• Windows Search Technologies Unable to cast COM object of type

  Hello, I tried to a function wrapper for my website which calls ExecuteQuery(...). I got this error when I tried to display the output from the internet browser: Unable to cast COM object of type 'Microsoft.Windows.DesktopSearch.Query.SearchDesktopClass' to interface type 'Microsoft.Windows.DesktopSearch.Query.ISearchDesktop'.

• .NET Development NetworkStream.Write/.BeginWrite do not seem to be working

  Hi, I am having a problem with a simple app I am trying to write to send data over TCP/IP to a server/listener. According to all of the documentation and code samples I have seen, my code is correct, but the server/listener (which I can observe on the same machine) does not receive any data. I can see that I am making a socket connection, and no exceptions are thrown when I call either .Write or .BeginWrite (I've tried it both ways -- the callback does fire when using BeginWrite, and asynchresult.Completed comes back True), but the server does not get anything. What am I doing wrong here I connect using this method: Public Function ConnectToServer() As Boolean ' make connection to remote server/listener If CheckC ...Show All

• SQL Server Package Validation Error

  I have a package which takes a text file and imports data into a SQL table. It returns the Package Validation Error: Error at Data Flow Task [SQL Server Destination [1430]]: Failure inserting into the read-only column "ZipCode". The column ZipCode in the sql table is a varchar(50) column. I do not understand why it thinks the column is a read only column; if someone could shed some light on this I would greatly appreciate it. Thanks! GN Okay I've confirmed that it is a permission error. When I use my login, which has sysadmin privleges, for the database connection there is no problem inserting into the table fields. When I use another login that does not have sysadmin privleg ...Show All

• Visual Studio Express Editions IDE Issue

  I'm coding in unmanaged code. And the intellisense is bad for unmanaged c++. I have to close the project and open it up over and over to get the intellisense to work for like 2 times then it dies ;_;. How can I fix this issue It's not dead, you ran into the infamous performance problems with intelliSense.

• SQL Server Database 'msdb' cannot be opened

  Anyone help I opened SQL Server management studio and tried to connect with the local database and received the error message: Database 'msdb' cannot be opened. It has been marked suspect..... I have pasted the only error from the event log I could find below, but it doesn't mean much to me. In the event I can't find what the problem is, and not being a database administrator, can anyone tell me what I can do to get back in working order without messing up all the databases in my SQL Server 2005. I'm afraid I only have a MASTER backup from several months ago, and am afraid if I use this, I will loose the latest data. I'm a novice, and do not understand the relationship of the master/msdb/model databases to my core custom databa ...Show All

• .NET Development HttpListener BeginGetContext does not seem to handle more than 2 request simultaneously

  Hi Friends, I'm trying to host a webservice that will receive/process multiple client requests simultaneously. For this purpose, I wrote the following code, but it does not seem to be handling more than two at a time. I put in a few console prints and have also attached the output. Here it goes - public void serverStart() { HttpListener _listener = new HttpListener(); _listener.Prefixes.Add(.......); _listener.Start(); while (true) ProcessRequest(); } public void ProcessRequest() { Console.WriteLine("PR " + ++count); //count initialized to 0 in beginning IAsyncResult result = _listener.BeginGetContext(new AsyncCallback ListenerCallback),this._listener); result.AsyncWaitHand ...Show All

• SQL Server matrix data area conditional formatting off max value

  I have a matrix where i'm trying to have the report select the maximum value in the data area (not including the subtotals) and bold that value. month day1 day2 day3 day4 total Jan 10 15 5 12 42 Feb 5 8 3 11 27 Total 15 23 8 23 69 I'm sure i will have to use the IIF function in conjunction with the InScope function. However i'm unsure on how to isolate to the max value and make sure the Inscope function does not affect the totals. any idea's are appreciated. Instead of using "......., IIf(Max(Fields!FACT_CUT_RELEASE_Count.Value), "Bold" , "Normal" )," you need to specify the scope over which yo ...Show All
