• .NET Development RijndaelManaged and Base64 - overflow characters after decryption.

  Hello fellow developers! I have a problem in two routines for encrypting and decrypting text files, it works fine except the decrypted file contains 3 extra characters " i ". Is there anyone out there that has experienced the same problem or has an idea for a solution I have tried using different PaddingMode settings but without getting closer to a solution. PaddingMode.None - Exception during encryption, "Length of the data to encrypt is invalid." PaddingMode.ANSIX923 - Ok but "i " at end of file. PaddingMode.ISO10126 - Ok but "i " at end of file. PaddingMode.PKCS7 - Ok but "i " at end of file. PaddingMode.Zeroz - Exception during decryption, "Invalid character in a Base-64 st ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Animating Billboards Using A Single Texture

  I just finished a basic billboard class that is capable of reading in multiple textures and animating. However, I would like to read in a single texture file and be able to simply change texture coordinates to change the appearance of the billboard. Now, I could recreate my VertexBuffer each frame, but that would be a lot of wasted processing. Is there a way to dynamically alter the texture coordinates for VertexBuffer objects each frame Edit: As a bonus question, how do I enable the alpha channels in my textures Right now it shows up white. I am using the BasicEffect. Would I have to write my own effect just for that Seems rather silly but I will if I have to. Edit 2: As bonus question 2, how can I disable antialiasing of my textures I'm ...Show All

• Windows Forms UserControl with ComboBox

  My aplication needs a usercontrol consisting a combobox. So I have to provide the commonly used propertiesfor the comboBox for this usercontrol as well. I build this UserControl DLL and using in some other Windows Forms, but then some problems arises. I have few problems in that: 1.

• Visual Basic Word border problem (declaration

  I want to set: WordApp.Selection.Borders = wdBorderBottom But problem is, that it says that wdBorderBottom is not declared. How can I declare it where are you obtaining the code from Of course if you get an error stating that the variable is not declared, then you need to declare it of course in order for it to work but I am guessing (unsure) that you are using COM Interop to access Word instance If so, you need to give it the correct parameters/properties/values etc... would help if you can supply where you are obtaining the code from so we can help ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How I get the skin weights?

  Hey, I am trying to understand how animations works in XNA. I have modified the content processor to get the vertex buffer of a mesh from a model in a raw data, and I believe that it is in the vertex buffer where the skin weights indices of each vertex for each bone is stored. Does anyone has some clue how to get the skin weights or how they are stored in the vertex buffer Or even better, does anyone know the proper way to retrieve the vertex buffer, index buffer and skin weigths from a model I am not sure if I undestand completly, but I promise I will take a look on what you suggest. My big problem is just I don't have direct access to the vertex information o ...Show All

• Visual Studio VS 2005 stalls/freezes when adding multiple DataGrids bound to a DataSet

  Hello, I have a form that has a main DataGrid bound to the parent side of the DataSet. There are 15 child tables to that DataSet, and for each child table I have a DataGrid on that form (most are really small, but do show related records when I scroll through the main DataGrid). When assigning the datasource for each DataGrid (in the designer) to its appropriate child table (and modifying each DataGrid) everything goes ok until I get to about the eighth one, then VS starts to slow down like it is running out of ram. I very seldom get to assign the datasource for the eleventh DataGrid. I thought it was a RAM issue, and bought a new computer (2.66 Core 2 Duo - 2 gigs of RAM) and it still does the same thing. Reboot and it comes right back to ...Show All

• SQL Server SSIS advantages

  This may be too general a question but I'm going to ask it anyway. I'm moving data from a source DB (say A) to a target DB (say B). On A I need to join 3 tables and, after some lookups etc., I need to populate several tables in B. Inserting into B's tables involves sequential operations because in many cases I have to get back the value of an Identity column to use as in input value in a another table 'downstream'. Additionally, the tables in B are populated as a group i.e. if the insert on any one fails the entire group's insertion needs to be rolled back. I set up a set of stored procedures to do this. The master Stored Proc opens a read-only cursor and for each row of the cursor executes the other SPs in proper sequence. Some of t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Confused About XNA and DX10

  I am confused about the differences between XNA and DX10; is that correct: 1- XNA will have both fixed function and shader programming and effects also 2- DX10 will have only shader programming with no assembly, no fixed function and no effects. 3- DX10 will be on Vista only, since it is shader programming will Shader 3.0 (DX9.0 C and L) is compatible with Vista shader 4.0, so a program written on Windows XP DX9.0 C will run on Vista DX9.0 L but will not run on Vista DX10 shader 4.0 But why it will not run on DX10 Vista runtime if the program is only shader with no effects is that because shader 4.0 will not be compatible with shader 3.0 or it will run regarding windows controls with DX: 1- can we build application ...Show All

• .NET Development Controlling values from a Combo box

  Hello, I am very green at this and I'm hoping for a bit of help. I've created a very basic program that creates some html code based on what a user enters. One of the fields they complete is "DIVISION" (I've called the combo txtDivision). There are four pre-defined selections - but you have the ability to enter in others. The combo simply displays the company division. I also have four company logos, one for each division. "FGSig.gif", "FSSig.gif", "FGSig.gif" and "FHSig.gif". If the user enters their own division, or leave division blank, "FGSig.gif" should be used. I have declared the logo as image and the company sub division as division Each logo is located on a web server. ...Show All
