Use the System.Diagnotics.ProcessStartInfo class, set the UseShellExecute property to false, and the RedirectStandardInput, RedirectStandardError and RedirectStandardOutput properties to true. You can then use the StandardInput, StandardError and StandardOutput properties of the Process object to send input to the program and read the output.

Hi Eveyone.. I have sample code of install shield express serial key validation dll. I want to convert this c++ code to c# but i don't know where should i start. I need your help.. Thanks...
Here is the code:
<br />
#include "stdafx.h"<br />
#include <tchar.h><br />
#include <stdlib.h><br />
#include "ValidateSN.h"<br />
<br />
BOOL APIENTRY DllMain( HANDLE hModule, <br />
DWORD ul_reason_for_call, <br />
LPVOID lpReserved<br />
)<br />
{<br />
return TRUE;<br />
}<br />
<br />
LONG WINAPI ValidateSN(HWND hwnd, LPSTR szSrcDir, LPSTR szSupport, LPSTR szSerialNum, LPSTR szDbase)<br />
{<br />
if (_tcslen( szSerialNum ) != SERIALNUMBER_LENGTH)<br />
{<br />
#ifdef _DEBUG //Display Debug information<br />
MessageBox(GetFocus(), "Serial Key is Invalid!", "Validation Failed", MB_OK); <br />
#endif<br />
return VALIDATION_FAILED;<br />
}<br />
<br />

wsprintf(szTmp, "szSerialNum=%s. \nField #1=%s \nField #2=%s \nField #3=%s", szSerialNum, szField1, szField2, szField3);<br />
#endif<br />
<br />
if (ValidateField1(szField1) != VALIDATION_SUCCESS)<br />
{<br />
#ifdef _DEBUG //Display Debug information<br />

#endif<br />
<br />
return VALIDATION_FAILED;<br />
}<br />
else if (ValidateField2(szField2) != VALIDATION_SUCCESS)<br />
{<br />

{<br />
if (_tcsicmp (szField1, SERIALNUM_FIELD1) == 0)<br />
{<br />
return 1;<br />
}<br />
else<br />
return -1;<br />
}<br />
<br />
LONG ValidateField2(LPSTR szField2)<br />
{<br />
<br />
long lNumToValidate = atoi (szField2);<br />
<br />
if ((lNumToValidate % 3) == 0)<br />
return VALIDATION_SUCCESS;<br />
else <br />
return VALIDATION_FAILED;<br />
}<br />
<br />
LONG ValidateField3(LPSTR szField3)<br />
{<br />
return VALIDATION_SUCCESS;<br />
<br />
}

learn C#
the string object is your friend and the Convert class is your buddy
LPSTR becomes string
all the _t type functions have equivalent methods for string objects
and the atoi can be handled by a Convert.ToInt32(...)
Technically speaking the dictionary would define Visual Basic users as programmers.
But here again, a very generalized, liberal definition is being employed and it's wrong

Thanks. but my problem is entry point of function. install shield does not found my function written in c#. i have to export function for external use like this
extern "C" _declspec (dllexport) <br />
int validatethis(const char * szSerial)<br />
{<br />
.....<br />
...<br />
}<br />
i dont know how it is make in c#..

ah - I see - I assumed that you were just wanting to use the same code in some C# project.
daft question but why are you writing it in C# if it works fine with installshield in the form that you have it?
Anyway what you have to look into is called 'interop', but I don't think you can as I think MS worked on the principle that C# will want to call API but not the other way - a .NET dll is not the same as a normal dll and has different structure and thus LoadLibrary etc will not cope
I think what you might have to do is wrap the C# object in managed C++ (which I think you can export)

What you are talking about here is a Explorer Context Menu Shell Extension.
There are a series of articles written by Mike on how to do this using VC++. If you would like to do the same in C#, there is lot of work to be done. There is a technology sample that comes along with framework sdk, which would help you go about this thing.
Here are the links that could help
The following is one of the samples, but does not directly what you want, but gives you an understanding of things involved in writing one.
http://www.codeproject.com/csharp/dateparser.asp[^]http://www.codeproject.com/shell/shellextguide1.asp[^]
The sample from framework sdk

Hope this helps.
Cheers

If you don't need the functionality of a COM shell extension then you could get away with some quick registry additions.
Add
HKEY_CLASSES_ROOT\Folder\shell\&Command To Display\command
and set (Default) to pathtoexe\program.exe
You can play with "'s and the command line arguments passed (%1) if needed.
This will display for any folder that's right-click on. You could instead add it under the HKCR\Directory tree or create your own association. It just looks for the shell & command keys.

Hi
Is there any way to create a control in C# and use it in non .Net (MFC 6) program?
thanks

Yes, but it isn't cut and dry and NOT supported by Microsoft (in the early beta's it was possible, but was later removed and now the only supported non-.NET host is IE).
Essentially you have to implement all the COM interfaces that a standard ActiveX control would implement. I believe there is an article here on CP which explains what you need to do, Exposing Windows Forms Controls as ActiveX controls[^].
You will probably have to do some conversions between the class names used in Beta 1 and the ones that made it into 1.0 (for example System.WinForms is now System.Windows.Forms and System.WinForms.RichControl is now System.Windows.Forms.Control or System.Windows.Forms.UserControl).

It sounds like you would just have to implement the COM registry stuff yourself. MS probably pulled this feature to get away from having to support older systems and concentrate solely on a .NET push. After all activex is just an exe done in COM and it's rather easy to write com controls in assembly language once you see which registry entries + class interface methods are expected.

The response I heard was it was pulled because they didn't have time to test all possible permutations of how it would be used. By only supporting IE as the host, they had much less they needed to test/debug.
At the time they said the feature would be coming back later, after it could be tested. Who knows what Everett/v1.1 brings?

How do I find out which item is activated / doubleclicked in an ListView DoubleClick / ItemActivate event?
I guess I have to cast the EventArgs to something very clever - but what, and how to find out?
TIA

Use the GetItemAt method of the ListView passing in the current mouse position in client coordinates (you can get the position by the MousePosition static property of the Control class).

How can i run C#.NET applications on Linux?

Well...
You can run the Shared Source Common Language Infrastructure[^] on FreeBSD and MacOSX.
However, for Linux, you're going to want to look at The Mono Project[^]

Hi, I need a way to find if the computer is connected to internet at the time my program runs on. Is there any?

Make sure your help notes include that. When using this application you must ping or connect to a website to make sure are connected.
There is an API that escapes me that tells if the machine has an active connection. You could also create a WebRequest and try attempting to connect to a well know site then have your application respond accordingly.
|
|
|
|
|
I believe the only api availiable for online status is for dialup connections. Won't help for broadband. The best solution is just to ping an outside server.
|
|
|
|
|
The same way the network status systen tray icon is updated when you log off or pull your network connection.
I just can't remember the function call now. I found it once for a project but never used it.
|
|
|
|
|
I think the API you are thinking of is 'InternetGetConnectedState' all part of the WinInet library
