Hi,
I need to be able to recognize excel-like cell-references (i.e. 'Sheet1'!$C4 ) and have a regular expression for that, which works just nice. However, users should be allowed to encapsulate a such field (or a plain number for the sake of simplicity) in parantheses (spellcheck..) like ((12)) as this is syntactically correct. However - there has to as many opening '(' as there is ')'. I cant just count these, as a field reference may include e.g. a '(' in the sheet-name.
So, is there any way with C# regular expressions to count and compare counts of certain characters ? The regex for the simple example could be
"[(]*[0-9\.,]*[)]*" - which would allow an un-even number of opening and closing parantheses.
Any tricks to do this ?

Doesn't (\([0-9\.,\]*\))* work?

If I'm not mistaken there is no regular expression for what you need to do because the language you descibed is not regular.
So I guess you will need to write a custom parser or use a parser generator such as this one http://www.codeproject.com/csharp/spart.asp.

Hi
How do I add a custom MenuItem on a MainMenu,ContextMenu or Menuitem? Is there an event I can override?
I have made a collection designer property on them all, where I can add custom MenuItems, but that only works when using the property editor. What I whant is, when u have f.ex. the MainMenu activated and click on an empty menuitem field, that a custom MenuItem is added instead of the standard MenuItem.
Any hints, workarounds articles? I can't seem to find any.
TIA

Hi all,
I need some samples for licensing the windows form application.My criteria is whenever user attempting to login the application i want to check the license key which is stored in a database table. The way to generate the license is, wherever application is installed, a KEY is generated with that computers CPU number.When user is logging in, how do we check this, (i.e.) we have application running on a server 10 users who are connecting to a server, we don't have to install the license on all the clients (PC's).
This should be checked only on the server side.
We should check the license when any one connects to a server (MSSQL) (I don't want to install license on every client, it should be only on the server, here ever the MS SQL you have installed or connecting to)
Any body have idea about this type of requirement, please send me the code samples or documentation .
thanks

Considering most machines have their CPUID's turned off by default, and some machine don't even have them, why would you want to create a license key using this number? It's an unreliable source...

I've been playing with the new Visual Studio 2005 beta and am quite impressed with the potentials of the built-in "ClickOnce" deployment scheme.
I've deployed (err, 'published' according to VS) my company's application to a network share using Visual Studio 2005 beta. When I try to run the .application file from the network share, all goes well, until a message box pops up telling me that the application has been blocked because it 'poses a high security risk'.
My question is, is there some way to allow all the users on our corporate network to run the application without having to configure each and every machine? Isn't there some way to make ClickOnce popup a dialog saying "hey it's dangerous, but it's your data. yes/no"?

If a Visual Studio application is compiled on a Windows 2000 Professional operating system, even as simple as an unmodified form, and the program is attempted to be run from a computer with a Windows 98 operating system, could this be the reason why the project has an error? Does the file need to actually be compiled on a Windows 98 machine, or is there in fact a version of the .NET framework specifically designed for Windows 98?
Attempting to load a simple form onto a Windows 98 machine, and the .NET framework has been loaded. What could account for the error message, as there is not even a single line of code written on the form that is attempted to be run on the Windows 98 computer. Works fine on Windows 2000 Professional.

Virtually all of the .NET framework should work on Windows 98. A few things, such as the XP themed visual styles, System.IO.FileSystemWatcher, and a few others don't work on '98.
That said, a default Windows Form app without any user code to my knowledge should work ok on '98. Is the correct .NET framework version installed on the target 98 machine?

The error message that I get with just a simple form with no code is as follows: What could be the problem?
Application has generated an exception that could not be handled.
Process id=0xffef253b [-1104581], Thread id=0xffefab87 [-1070201].
Click OK to terminate the application
Click CANCEL to debug the application.
Any advice as to what the cause could be?

Again, it seems the .NET framework is not installed. Be sure the lastest version of .NET is installed on the target meachine.

You can't run the development environment on Windows 98, and compiling on it is not supported.
I agree with the other posts, make sure that the .NET Framework installed on 98 is the same version that you compiled the app under.

I want to extract the email ids and names (if any) from the emails content. The emails may contain forwarded emails as well, so I should be able to extract the email ids within those forwarded messages too. I want to do it in C#.

Hi,
Is there anyone can see all exe structures: functions, parameters list, constants, properties or even events?
If anyone can do it, is it possible to use that functions or events?

You can decompile an exe, but you won't get proper variable/function names, and you certainly won't get comments. You'll get code that compiles back into the same exe, with generic names for everything.
Microsoft have a tool to do this, I think it's called disasmil or something.

It's called Ildasm.exe and is located in your \VisualStudio\SDK\v[number]\bin\ directory. If you're doing decompilation, I'd recommend the free Lutz Reflector which can examine .NET assemblies and generate the equivalent IL, C#, VB, or Delphi).

Ok, thx. But can we can do it on unmanaged code?
|
|
|
|

short answer: no
long answer: no. Why do you post it to C# forum then? AFAIK C# is managed language (it translates to IL).

Well, you could use ngen.exe[^] to compile an assembly to a native code image and then decompile that into C or whatever you have a decompiler for. I know that this information is 100% useless but I just wanted to complete your long answer. 
Best regards

Thank you! Sometimes I feel like that too (in general, not neccessary your answers).

Hey all.
I need to make a program that can make screenshots of other windows (that is other applications in windows). It needs to make continuous screenshots so the my program probably needs to use the HWND information of the window in question. The optimal case would be that my program can make "screenshots" even though the window it needs to capture is minimized, is this possible?
Can anyone help?
Kind regards from Casper

If the window is minimised, it is not being drawn, and there is nothing to capture.

Yeah, it's not possible to capture a window that is not visible.
