You can check it in the keypress event of textboxes and suppress it by setting e.Handled property to true.

you posted a whole lot of useless code here.
Handle the keypressed event ( as someone said ) and set e.Handled to equal !(Char.IsDigit(e.KeyChar) || Char.IsControl(e.KeyChar))
I may have some variable names wrong, the key thing I wanted to add, is that unless you check Char.IsControl also, your control keys (arrows, delete, etc ) will not work

Yes, of course it's possible. You'd use the same APIs, if you were going to use C++.NET. If you were just going to use C++, you may find you wanted to use p/invoke to get to the APIs you would use in C++.

thank u sir for suggestions.
Sir i havent used c++.net i only knew that remote screen capture and remote installation is possible in c++.net hene i dont know the api's can u reply me with list of api's required for this application?????
Another problem i faced in c#.net is "DATATYPE CONVERSION"
the problem is that according to MSDN LPTSTR,LPSTR,WORD,DWORD are the datatypes of windows o/s which are directly supported by c++.net
I have invoked the functions in user32.dll , kernel32.dll to standby , restart , shutdown, hibernate the pc but when i tried to create desktop using createDesktop() given in MSDN i faced problem of datatype conversion from c#.net type to windows or c++.net types
I want to know that how to convert such datatypes to c++.net types or windows types
please reply me if u have any table consist of datatype conversion

Hi everyone,
I'm working on a monitoring app in C# and would like to retrieve the temperatures of various sensors on my motherboard.
I'm specifically interested in the CPU and motherboard temperature sensors.
My first thought was to use WMI to read these values. I've tried the Win32_TemperatureProbe table among others, but the CurrentReading prop is not populated. (More info see MSDN article here)
I've found that the sensors should be accessible through the SMBUS on the mainbord.
So my question to the community: Does anyone know how to read CPU and mainbord temp sensors? Or can you help me to gain access to the SMBus?
I've been told these values should be quite easy to read using some low-level bios access (using assembly), but I'm looking for a way to get these values using C# and .NET 2.0 framework.
Any help would be greatly appreciated!
Thanks in advance!

Thank you!
This could indeed be helpful!
This article explains how to execute assembly code from c#, however I don't know any assembly myself.
Can anyone point me to some information to read the sensors with assembly?
Thanks!

No I don't know 
This might give you a little bit more information http://www.thescripts.com/forum/thread382910.html

you can collect such datas through ACPI
I recommend to see NHC (Notebook Hardware Control) however it's for notebooks but I installed it on my Desktop and it works! atleast get voltage values and temps

DO you know if the developer has managed to get a version working in Vista yet?

Hi all,
I'm using Microsoft OLEDB Provider to read DBF files. But i just can read the file with less-than-8-character file name.
Accidentally, I installed BDE (Borland Database Engine) and it solved the problem i presented above.
I can't understand.
Hope you helps me to figure it out
Thanks

Hi,
I have developed a C# based windows applications. It has been installed on a numbers of client machines (say 100 machines).
Now the client wants to change some requirements. So I have made those changes and now want to update all those 100 machines.
Is there some easy way to do this update process using versioning info. As client machines are at different geographical locations. So it is very difficult to go to each machine one by one and do update process.
I want to automate this process which may use (not necessarily) some web service to check version of installed and latest available version .... and then automate the installation process if newer version is available.
If anybody of you can help ... you are most welcome.
Thanks in advance.

dudes,
This is not the code problem. analyze problem only.
Can you help me to analyze.
Heres the scenario:
I have an application with search button and a textbox, etc.etc.
When I input the ID on the textbox and click search button. It will show the data and it can be editable and update. I have no problem on that. The issue is that when the application is distributed on different pc and it will access on the same database. What if the user will search the same ID. Who will be the one can edit and update the data. Think about excel file. If you access both file, there is a pop up window that says READ ONLY.
"How the Microsoft do that?"
Problem: How? What?

Easy. Open the folder that the xls file is in, then open it. Notice that when it's open, a temporary file, based on the filename of the XLS, is created. They delete that to remove the lock. If you turn your computer off while it exists, on older versions, you had to delete it yourself ( perhaps not now ).
This isn't going to help you, tho. You want to mark a row as locked to a user when they start to edit it, and impliment a timeout, in case they turn THEIR PC off.
