• Visual C# Speed comparison: Filestream.Seek vs. StreamReader

  What's the fastest way to access the contents of 300,000 variable length "records" in an asynchronous manner  A "record" is a text file approximately 20KB long. Here are some possibilities that I've considered: 1. Store each record as a file & store the file path location (ie: C:\test.txt) of the record. Use the StreamReader class (and File location ability of Windows Operating System) to locate, open, and read the file. 2. Combine all records into 1 file & store the record's location in the file (ie: byte 240 of 240000) and record length. Use the Filestream.Seek method to locate the starting file position and ...Show All

• Visual C++ About my screen shot

  Hi, I am writing a screen shot program with CImage object. I created a CImage object with Create() where I set the cx,cy, and bpp (bit per pixel) as the parameters. I set the cx=428, cy=302, and 24 for bpp for my CImage object. After taking a screen shot with my program, I saved it. Then, I opened the screen shot with Paint Shop Pro and check it on the resize window (through "Image | Resize" menu command) in Paint Shop Pro. In Actual/print size setting on the resize window of Paint Shop Pro, I found the resolution of my screen shots are only 72 pixels/inch. By using my program, I like to take screen shots having 160 p ...Show All

• Microsoft ISV Community Center Forums Copying and pasting between spreadsheets

  I have an Excel Macro which copies from a Source spreadsheet and pastes on the working copy. The Source spreadsheet is the result of a report gleaned from a non Microsoft database. Usually all works as expected. The problem comes when one of the items in the working copy does not appear in the Source copy. (If no activity occured, instead of displaying a zero, that particular item is excluded from the output. Since the procedure is copying and pasting to a set Range, these instances cause a mismatch on the Master Sheet and incorrect data in the linked cells elsewhere in the Workbook. I know there is a way to have the copy and paste tak ...Show All

• SQL Server Size of database seems a bit large

Is this normal Could be...that would depend on the schema of your database, column data types and sizes, way you are importing data, recovery model being used, etc., etc., etc. Would need much more information to say if it is or not, but a start would be by providing a script of the table(s) that make up the database (if it is only 1 or 2) and number of rows in each table...also anything on how you are loading/importing the data ...Show All

• .NET Development How to give an exe the permissions it wants

  I'm trying to write a c# CGI app. When i simply use Console.WriteLine to output my results, everything is fine. But I want to use HTMLTextWriter and when I do, I get the following error below. When I run the program in a console it works fine, but not when I access it from a browser.

• Smart Device Development stream in vs 2005

  Hi, I write a program for pocket pc 2003 in vs8 beta 2. I am using cout,cin,cerr...etc.And i compile without the error. But i can't see anything in the emulator of pocket pc 2003 in vs 2005 Can you explain to me Does vs8 really support stream for pocket pc PocketConsole works for me on WM2003SE. BTW, it is not a CMD shell program. It just displays the output directed to stdout and reads stdin in a cmd like window when a console program is executed. The window closes if the program terminates. So if you have a short lived program you should write something like getchar() before its return statement so that you have time to read the out ...Show All

• Visual Studio Team System How do I delete a task?

  In going through the walkthrough, I accidently created a duplicate of a task. Is there some way to delete it ("Delete" doesn't seem to work.) There is no support for deleting work items in TF. You may want to just change the state of the task. If you truly want to delete the task you will have to remove entries from WorkItemsAre, WorkItemsWere, and WorkItemsLongTexts tables in TfsWorkItemTracking database (I am assuming you did not add any links or attachments to the task). -Mohammad ...Show All
