• Windows Forms Checking for special characters in text control

  I have an IP address text box that takes in multiple IP addresses (space separated). I would like to restrict the user to enter only - numbers, "." and whitespace. How should I do it i mean, without having to do a strchr check on every alphabet (lower and upper case, special characters like "! @ # $ %.....". Is there an easy way for me to do this check Advise please... you can check the key they pressed and or check to see if its a digit, space or a period so in the textbox, implement a keypress event. then try this: if (!Char.IsNumber(e.KeyChar) && !e.KeyChar.Equals('.') && !e.KeyChar.Equals(' ')) { e.Handled = true; //we handled it so it wo ...Show All

• Smart Device Development RNDIS protocol

  Hi, I am new to windows network driver development. I had some queries regarding RNDIS driver. Since less resource are available on net; any help is always welcome. How can I support new RNDIS compilant device (e.g ethernet adaptor) in my PC. Windows XP and Windows CE .NET operating systems have built-in support for RNDIS.

• SQL Server DataReader output column length

  Hello, I have an ODBC connection manager to a Progress database. In that database there is a column declared as a string of 10 characters long. However, some data in this column is actually up to 15 characters long. This makes my DataReader Source fail everytime I try to run my package because it sets the output column like this : Datatype : Unicode string [DT_WSTR] Length : 10 Is there any way to solve this without changing the datatype in the Progress database (that is beyond my control) tanks in advance ... Same issue happens to me. We import data from a Thoroughbred basic database. The field can be 12 chars long with 20 chars of data. In the Thoroughbred world, this is just an "integr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Compressed texture

  It is possible to create a compressed texture with D3DXCreateTextureFromFileEx. Is it also possible to "manually" create a compressed texture Lets say we create a IDirect3DTexture9 object with the D3DFMT_DXT5 specified. Now you want to fill this texture with data. So, if you lock the texture buffer, you then fill it with uncompressed data and it will be compressed after you unlock it Or do you need to fill the locked buffer with compressed data Also, if you create the texture with several levels of mipmap, after locking the buffer and writting into it, will the object create all the mipmap levels after the unlock You can use D3DXLoadSurfaceFromMemory() to fill a texture's certain m ...Show All
