But before it add attribute runat, server for the dynamically added control -here your textbox.

According to the requirments i have to present a documentation of my project in such a way that it includes complete lexical analysis(class and value part table) of my compiler. I just need an idea which can lead me to the begining of the documentation. If anybody can tell me as soon as possible i will be very thankful! THANKING YOU!

We'd never have realised it was any more urgent than the thousands of other "urgent" messages without you telling us. There's this wonderful tool called Google that may have slipped your attention.

Now it's clear, and Pete hits the Bullseye! All the best, Martin WinUSB.dll help urgently needed 2k1Toaster13-Aug-07 21:43 2k1Toaster 13-Aug-07 21:43  Hello everyone. I am having quite a problem with this. I am developing a project board that uses a Microchip PIC, and up until now I was using the general Microchip provided dll along with some snippets of code I bunched together. All I needed was a way to send 64bytes of data out and receive 64 bytes of raw data. That is it. That is still all I need. If you want to jump ahead to the problem look for "===========PROBLEM===========" below... Otherwise this is the full story. The problem is that Vista does not play nice with this dll. So I am forced to use WinUSB which is fairly new and very little documentation I can find. And to compound the situation, the little code I find, is all written for C++ or contained in header files. I need to get this working in C#, and I need to do it soon. If anyone can help I would greatly appreciate it. From my understanding I need to first crete the inf file, with the correct co-installers as well as a unique GUID. This I have already done and it is successfully recognized by Vista and XP. Then in my program I need to search the registry for a particular GUID (the general USB hub for some reason), and then iterate through each one found until I find one that contains my vid/pid in its description using SetupDiGetClassDevs and SetupDiEnumDeviceInterfaces from the setupapi.dll. I believe I have this working as I can iterate through and find my device. Then I need to Create a file of some sort to interface with. From my searching I found this is what I should use: Intptr TheWindowHandle = CreateFile(strPath, GENERIC_READ | GENERIC_WRITE, 0, IntPtr.Zero, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, IntPtr.Zero); Then I must initialize this file by passing in the IntPtr I get with that, to WinUsb_Initialize which spits out some other IntPtr. I take that pointer and call WinUSB_WritePipe and WinUSBRead_Pipe. I have no way of really knowing if I have this correct unless someone is to chime in and support this. My problem though is this: ===========PROBLEM=========== I do not know how to declare the [DllImport] of winusb.dll for WinUsb_WritePipe and WinUSB_ReadPipe nor what values they take or return. I would gladly appreciate any and all help on this and specifically C# examples. If you are willing to write the small snippet of code needed, I can compensate you for it. If you need any more information about my source code or the winusb dll or the application, just let me know. I thank everyone in advance for the help.
