This is doable, but would be a fairly complex application to pull together. Off the top of my head, what you would be looking at here is parsing a form using reflection (fairly trivial to accomplish), and pulling out attributes. Now, depending on the status of these attributes, you would probably need to parse the IL if you need to add an identical version in, and this would require you to Emit this into your newly created object (which you could create using the CodeDOM).
All in all, doable, but not trivial to implement.

Yes, it would be possible, however it seems like sledgehammer-and-nut territory: if you know enough from compile-time decorations to create a new form class, you know enough at coding time. And if you know how to build the code to make a new form, you know how to instantiate the new form and add controls to it at runtime. I don't see the benefit of creating a runtime type over doing that.

Hi All,
I am calling a c++ dll from c#. it throwing error like "An unhandled exception of type 'System.AccessViolationException' occurred in exe
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
[DllImport(@"D:\Project\Working\Toolkit-2.0\output\Win32\Debug\ipetk.dll",
EntryPoint = "?GetModuleTypeString@ModuleIndex@Infrastructure@IPETK@@QBE?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@XZ",
CallingConvention = CallingConvention.Cdecl)]
static extern string GetModuleTypeString(ModuleType ths);
string ModuleIndex = GetModuleTypeString(ModuleType.IPD);
MessageBox.Show(ModuleIndex.ToString());
how can i resolve this issue..? any help will be appriciated.
Thanks
G.Paulraj

This one must be in the declaration. What is the return type declared at on the C++ side? Are you sure it is defined as C call convention?
I suspect you need to marshal the string differently. See [MarshalAs][^].
|
|
|
|

Looks like the definition of your C function should be changed to something like:
extern "C" char* GetModuleTypeString(char*);
STL strings do not work well between managed and unmanaged code.

The error message can also originate from a DEP (data execution protection) problem. If you get the error only when you run your compiled executable directly, but not when you debug from Visual Studio, set the DEP flag off:
editbin.exe /NXCOMPAT:NO "$(TargetPath)"

What is the exact problem?
What did you try already?
In what control are you showing the string?
What is highlighting for you?

this is my Requirement
if you can , please send me the C# code for it
|
|

|

OK. First of all, I will not GIVE you any code. I will however try to help you on your way.
The textbox is the wrong control for this. You should use a richtextbox.
Look here[^]
Especially have a look at the properties SelectionColor, SelectionStart, SelectionLength, ...
Hope this helps.

I have a C#.net 2010 new application that I am writing where I use linq to sql so I can work with the datacontext object. On the first menu tab page, I update the 'main'table with default values and values the user enters. The user clicks the next button the user is allowed to change some values based upon when customers submitted work. Basically some of the dates that are loaded on the first page come off of a schedule due date table. If the customer submits various parts of the paperwork late, the user changes the dates in the database.
So the question is if a date was loaded into a sql server 2008 r2 datqabase, and the user finds that they need to change the value to NULL is that allowed? Basically on some of the paperwork that is supplied by the customer if they do not supply a date, the data needs to be set to NULL. Thus in the application how do I pass the null value to the database via the datacontext object? Do I pass the value as '' or 'NULL', or some other value?
Thus can you tell me how to pass this Null value to the appropriate column in the database?

Hi ,
How i Can open my c# form only automatically to user when user open windows.
|
|
|
|

You will probably need to add it to the registry in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. But you may find that your users have their own ideas as to whether they want this to happen or not.

Even simpler is adding a link in the startup folder (C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup).
|
|
|
|

no your screwed, close your computer, take out the hard drive
open your hard-drive and throw away the cover( this is what makes computers lag!!)
then take out the RAM and place a hot dog in there. Pour water into the cooling fans, turn it on and BAM!!!
faster computer along with the use of the program in all users
YOUR WELCOME!!!!

How i can do this by coding automatically when program setup
|
|
|
|
|
Add a link in the startup folder, you'll find that in the category "file system" in the setup project.
|

I agree with others with either using the Registry and StartUp folder. However, there is also one more alternative if not more to consider. Why not try creating a Service?
Here is an article to get you started. MSDN: Walkthrough: Creating a Windows Service Application
Once that is done you can go to the Component Services and set the application to start once the computer has turned on. There is also very cool recovery options. (dcomcnfg)
Hope this helps!
