• Visual Studio Bug: Report only prints correctly from print layout screen

  Btw, is there an official location to post report viewer bugs On two PCs, the user can only print if they click Print Layout first. If they click Print from the initial screen (whats that called ) then the report does not print correctly. As follows: 1) On first PC, only top half of each page prints. 2) On second PC, a single page will print, with this error data on it: PCL XL Error Subsystem: KERNEL Error: Missing Date Operator: ReadImage Position: 1222 Both PCs have report viewer v2.0.50727. Report prints fine if they click Print Layout first. There are several known issues with winforms printing. These have been addressed with Visual Studio 2005 SP1, so make ...Show All

• Smart Device Development Download File from the Internet

  Hi, I've got my program to succesfully connect to a website and then read the contents of that page with HINTERNET.  But now I would also like to be able download a file off the internet and store it locally on the machine.  I could, in theory, just go to the file online, read what is spat out, and write that contents to a file.  But these files might be 100kb, which is too much to store in an INTERNET_BUFFER. Can I simply get the whole file and place it on the machine in one go Cheers, Dan. Thanks for the reply avinash. I actually found a built in function called URLDownloadToFile. Give it a web file and a local file name, and it will put that web file in your local file. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 10-bits per component graphics

  I need to output 10-bits per component graphics but the System.Drawing.Color class only allow 8bits per component (0-255). Any idea You'll need to perform the appropriate enumeration to determine what backbuffer/display formats the device is capable of. If it will only allow 8888 formats then you're a bit stuck as you can't really force the hardware to do something its incapable of. If 2-10-10-10 render targets are supported you could do all of your intermediary rendering at a higher precision and then sample it down to 8-8-8-8 for the final output. This would be fairly similar to how FP16/FP32 HDRI rendering works - the intermediaries are floating point but the output is still 8-8-8-8 (usually). ht ...Show All

• SQL Server transaction inside a data flow task

  We are designing an ETL solution for a BI project using SSIS. We need to load a dimension table from a source DB into the DW; inside the DW there are two tables for each source dimension table: a current dimension table and a storical dimension table. The source table includes technical columns that indicate if each record was processed correctly by ETL procedures. Each row in the source table can be a new record, or an exisisting one. If it's a new record, a corresponding new record should be inserted into the current dimension table of the DW; if it's an exisisting one, a new record should be inserted in the storical dimension table and the existing record in the current dimension table should be updated. Furthermore for each ...Show All

• .NET Development Search and Replace

  Hi All! I'm writing a program using VB.NET 2003. Ultimately I am attempting to write a function for my program to search and replace PHP code. The tricky part is that the code will never be the same. I just need to replace one chunk of code with another chunk of code. I actually have it working right now using the standard replace function in VB.NET but it's not as robust as I would like due to the leading spaces or tabs at the beginning of each line of code. So for example I might search a PHP file for this chunk of code... if ($error == false) { $sql_data_array = array('customers_firstname' => $customers_firstname, 'customers_lastname' => $customers_lastname, 'customers_email_address' = ...Show All

• Visual Basic Array starting at 1

  I'm redim a array to start 1 and to go to 600, does anyone know how i tryed using the "to", but never worked ReDim Preserve Array(1 to 600) In general using the 0 based arrays is recommended - VB (and for that matter C# afaik) doesn't support creating non 0 based arrays. If you really, really want to do so, you can use the array class to create an instance that isn't 0 based: Dim a As Array = System.Array.CreateInstance( GetType ( Integer ), New Integer () {600}, New Integer () {1}) Note that this array will not be strongly typed, so it will require several explicit conversions if option strict is on. ...Show All
