Sonia Gupta1-Jun-07 23:33 Sonia Gupta 1-Jun-07 23:33  Serialization is the process of writing the data in a class, i.e. the values of its properties - into a string that can be written to disk, or sent to an object in a client program. It's approximately the equivalent of putting data into a DBF. So what's the big deal? Re: Serialization.... Dave Kreskowiak2-Jun-07 9:06 Dave Kreskowiak 2-Jun-07 9:06  You may want to read up on Serialization[^]. You've generalized it way too much. Serialization converts an objects data into a trasmittable or saveable form, be it binary or text based.

Navneet Hegde3-Jun-07 21:02 Navneet Hegde 3-Jun-07 21:02  yes , Serialization is Process of packing data , but added it encode the data pack's it so that it can be sent over wire. Main advantage of serialization is that it ca be used to access object between different Processes over different machines.

Regards, Neal Re: Create a login username & password Christian Graus2-Jun-07 0:33 Christian Graus 2-Jun-07 0:33  OK - VB6 is a dead language. You need to specify if you're using VB6, as people will assume .NET otherwise.

LachlanGro1-Jun-07 22:19 LachlanGro 1-Jun-07 22:19  Hey All, Was wondering if someone could shed some light on the use of the System.Drawing.ImageFormatConverter class in VB.NET (2005). Could someone provide an example as I'm getting no-where: dim pBMP = new Bitmap("c:\test.bmp") dim pCON as new System.Drawing.ImageFormatConverter() pCON.ConvertFrom(pBMP) ...Now where to? Any help would be appreciated. Thanks In Advance. Lachlan. Re: System.Drawing.ImageFormatConverter.. VB.NET Help! Sonia Gupta1-Jun-07 22:27 Sonia Gupta 1-Jun-07 22:27  Try this link Re: System.Drawing.ImageFormatConverter.. VB.NET Help! LachlanGro1-Jun-07 22:32 LachlanGro 1-Jun-07 22:32  Thanks, The example in the link converts file formats, where my purpose is to convert the colors in the image from 24bpp to 16bpp bitmaps. Therefore I believe I need the ImageFormatConverter. Cheers Lachlan. Re: System.Drawing.ImageFormatConverter.. VB.NET Help! Christian Graus1-Jun-07 23:27 Christian Graus 1-Jun-07 23:27  The easiest way to do this is to create a 16bpp bitmap and draw the 24 bpp bitmap onto it. You can probably also use the color matrix to do this. In fact, the way to do it is just to strip the least significant bits of the red, green and blue component of each color. That is, if you wanted to build it yourself, which you probably don't. The ImageFormatConverter converts between file formats, as in gif, jpeg, etc. So MSDN tells me, anyhow Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog "I am working on a project that will convert a FORTRAN code to corresponding C++ code.I am not aware of FORTRAN syntax" ( spotted in the C++/CLI forum ) How can i use visual basic for application... koolprasad20031-Jun-07 21:11 koolprasad2003 1-Jun-07 21:11  Hello frnds, i want to show a message box in word document, when i clicked the button in word 2003. for that purpose the method i used was : i took the button from visual basic tool bar in word2003,then i double click a button, it shows me a visual basic editor and i wrote a code to display a message box and save the word and exit from it, if i again open the word and click the button then nothing happens ..means no event fires..Why???????? where i am wrong ???? what should i do ? how can i use visual basic for applciation.. plz help...regards,Koolprasasd2003 Be A Good S/W Eng...
