• Visual Basic convert graphic to bitmap

  I have dawn a graph on a graphic and is need to convert this to a bitmap. How do I do this Next i need to disply the bitmap and draw more graphs on it. How is it done Any advise would be appreciated. Thanks in advance. Do you mean you've drawn onto a Graphics class, presumably in OnPaint Instead, create a Bitmap, create a Graphics instance from Graphics.FromBitmap, and then when you've drawn on your bitmap, draw that to the screen. To draw it to the screen, use the Graphics object passed to OnPaint, and one of the DrawImage overloads it has. If you make this bitmap a member variable, you can draw on it where-ever you like ...Show All

• .NET Development Simulate return data data from WS call

  Hi there, Im consuming an Axis/Java web service, that returns an object that contains arrays of sub-objects. For example a persons details with an array of EmailAddresses. This all works fine, I manage to call it without any problems. What I want to do is stub out the call to the web service to give a client a prototype to use for their integration work (they wont have the java system in place yet!). I wanted to achieve this by giving them a sample xml document, that could be deserialized from the xml document into the generated w/s classes. The straightforward way would be to load an xml document and create these objects by hand, is there a ...Show All

• Visual Studio Tools for Office Range.get_Information() is causing Application.XMLAfterInsert to be fired

  Hi, I am getting some strange behaviour which I am having a hard time reproducing in a new project. I know that without being able to reproduce it I am not being very helpful, but I am running out of options and time. I will keep trying to reproduce it, but in the meantime any suggestions you might have would be greatly appreciated. I have a Word Template project and I am using XML tags to mark certain parts of the document that interest me. I then subscribe to the Application.XMLAfterInsert and Application.XMLBeforeDelete events so that different parts of the application can be alerted of changes made to the document.

• SQL Server Certificate limitations in SQL Server 2005

  I have a Web site that has a database backend, which stores user information.  I would like to encrypt the user information in a granular way. My question:   Is there a limitation to the number of certificates that can exist in SQL Server 2005   I would like to issue a certificate for each user of my Web site, whereby the certificate is protected by the user's password (which I will not have access to -- the password will be stored as a one-way hash in the database).  The certificates will provide access to a symmetric key, which will decrypt row-level data pertaining only to a particular user.  The certificat ...Show All

• SQL Server Query Designer in SQL 2005 is total %#%!@

  What happened to the Query Designer   It's a modal window that doesn't allow you to drag tables from other databases into the query.  SQL 2000's verion of Query Designer was so much better than 2005.  What happened   Are the developers at Microsoft completely retarded   Also, why do I have to log into my database servers everytime I open "Server Management Studio"   Who thought up that nice feature   Probably the same brillant folks that redesigned Query Designer.  Why would you want to have a forced login procedure for every database everytime the program is opened.  Once again Micro ...Show All

• Visual Studio 2008 (Pre-release) What's the soure of this 3D rendering "bug"?

  I've run into some "rendering" problems using Viewport3D. Sometimes pictures tell more (than a 1000 words) so here goes: This first image shows the rendered viewport with a blue "floor" and a red "wall". As you can see, the floor has "spilled" into the wall. http://home.comcast.net/~tlanglo/WinFX/Attachments/WallAndFloor_NotOk.png The second image shows the same wall and floor, but doesn't have the same problem (there's still some problems, though). http://home.comcast.net/~tlanglo/WinFX/Attachments/WallAndFloor_Ok.png And here's the XAML file I used in the example: http://home.comcast.net/~tlanglo/WinFX/Attachments/ ...Show All

• SQL Server SSIS Connection Object and Expressions

  I have been writing a custom source adapter that uses a file connection within the connection manager. If I hard-code a specific file then the component works. However if I use a file connection that has an expression defined which updates the connection, for example when you have a for-each loop looping over a set files. The file connection doesn’t seem to re-evaluate expression each time you access the file connection via the code. Is there something that I am missing or is there a bug Where is the expression defined On the connection manager within the dataflow If so, it will only be evaluated once bef ...Show All

• Visual Studio install on same system as vs 2003?

  install on same system as vs 2003 I have beta 2 installed on a Virtual PC 2004 virtual machine.  Frankly, it is as slow as can be. I've given it 768 megs RAM.  Every antivirus I've tried slows it down to a halt. Since a GO LIVE has be issued, I'd guess it is stable enough.  In the virtual PC I had no trouble following the instructions and uninstalling previous versions. Is there anything with beta2 and sql server 2005 beta 2 that conflicts with vs 2003 and sql server 2000 dennist Virtual PC was a bust for me.  However, I installed beta2 on my host with vs 2003.  No problems.  ...Show All
