Windows Forms does not use the MFC application model. I think you'd have to save your main Form somewhere. Alternatively you could enumerate Application.OpenForms, but again, figuring out the main form would involve traversing the parent-child hierarchy and all sorts of complexity. It'd be much easier to just save the main form in some static property that can be accessed throughout the app.

if your project or application is named "Foo" then the main form object is the Foo. Just add a static Foo^ class variable to your Foo class and initialize it in the constructor.
for example:
public ref class Foo: public System::Windows::Forms::Form
{
public:
static Foo^ myFoo;
Foo(void)
{
InitializeComponent();
myFoo = this;
...
}
...
};
Then, elsewhere in your code you can refer to your "main" form class as Foo::myFoo
hope this helps

Hi
Does any one know how to change the UserStrings Values in the .Net Metadata in code?
|
|
|
|
|
huh? explain what you're trying to do please.
|
|
|
|

Thanks for th reply.
Firstly I created resourcestrings in Delphi for .Net to keep Strings seperate in the assembly that is available to change with a resource editor.
These strings are saved in the .Net Metadata in the assembly under UserStrings.
I need to change these values inside the app, not with a external resource editor.
Delphi for .Net Code
resourcestring
StrPlay = 'Lets play'
C# code
const string StrPlay = 'Lets play'
This whole thing is to change the whole app between different languages on the fly. Form changes work 100% on the fly. The problem is the strings that is hard coded in the source files that needs to change between different languages.
Hope this explain it better. I can explain in futher detail. Any code examples in any language will help.
Thanks for helping!

1. you should never hard code strings in the source files if you want to be able to easily do localization and internationalization.
2. create a separate resourcestrings assembly file for each separate language, named appropriately (typically using the standard 2-letter designation for each language).
the naming convention is usually something like:
<assemblyname>.en.dll for english
<assemblyname>.de.dll for german
and so on where <assemblyname> is some resonable name
3. unload the current resource string assembly and load the one for the desired language
does this help?

Thanks.
Can you give me some example code that shows how to load and unload the resourcestrings dynamically in a app.
I read that resourcestrings load only at app start up according to locale and that you cannot change the resourcestrings dynamically.

I am using the System.Threading.Timer timer.
Now if I have a interval set quite low say 10ms it is possible for my timer event handler to be queued as they cannot be prcessed because the UI thread is busy or another application is running. When the UI thread becomes free it then processes all the queued events at the same time.
Is it possible to determine programmatically the number of timer event handlers that are being queued. I want to be able to determine when there is a build up of queued event handlers.
Some code to demonstrate this would be useful.
Also, is it possible to limit the number of timer event handlers that are queued?
Thanks,
Liam

The Timer your using doesn't use events at all, so what your asking is pointless. The Timer "Tick" calls your code directly using a seperate thread out of the thread pool for each "Tick".
But, if you were referring to the Forms-based Timer, that uses a Timer Tick event.
LiamD wrote: Is it possible to determine programmatically the number of timer event handlers that are being queued. I want to be able to determine when there is a build up of queued event handlers.
No. I think you're limited to Peeking at the next message in the message pump, without actually processing it. I don't think you can peek at the entire message queue. Also, this process would take longer than the 10ms you have between events.
LiamD wrote: Also, is it possible to limit the number of timer event handlers that are queued?
No, it's not. The best you can do to prevent a stack of tick events is to disable the timer at the beginning of your Tick event handler code, then reenable it at the end. This will, of course, throw off your 10ms pace, but your code will be executing the Tick event as fast as possible. 10ms is not alot of time to do much.

Hi every one,
I am trying to develop a windows application which will run on touch screen LCD monitor.
but the touch screen requires bigger option button,check boxes, tab pages, scroll bars etc. in such a way that the enduser select the controls using his finger.
How can i adapt the .net windows controls for the touch screen application (like changing size,graphics etc.,)?
or is there any special controls available for touch screen in .net?
or is there any tool available to convert the normal controls to touch screen controls??
Please help...
Thanks & Regards,

Hi All,
I have a customised installer class inherited from System.Configuration.Install.Installer class.
Customised installer class again works as a base class for CustomInstallerExtended class which in turn is a base class for module wise installers as per my requirement.
Scenario is like this:
MyCustomInstaller inherits System.Configuration.Install.Installer
MyCustomInstallerExtended inherits MyCustomInstaller
InventoryInstaller inherits MyCustomInstallerExtended
I wanted some "custom action" before uninstallation of my inventory module. Say for example I want to execute some stored procedure before uninstallation.
In this case if a public overridable method say "OnBeforeUnInstallation" is given in MyCustomInstallerExtended class, which internally gets called on protected method "OnBeforeUnInstall" or any other relevant method given by windows installer, then the custom code can be written in the public overridden method "OnBeforeUnInstallation" in InventoryInstaller.
OnBeforeUnInstall method being a protected overridable method of windows installer class,it will not get fired in MyCustomInstallerExtended class.
AnyOne please help me out to know how OnBeforeUnInstall method can be used effectively to over come my problem statement or is there any other way out to solve the above mentioned problem?

Hello!
I want to draw points and lines in a picturbox previously loaded with an image. (C#.NET 2k3)
I am trying to do something like drawing a red point where I click on the image. I do this, for example, in the MouseUp event, but nothing happens:
Graphics graph = Graphics.FromImage(pictureBoxHM.Image);
graph.DrawEllipse(new Pen(Color.Red),400,400,400,400);
pictureBoxHM.Update();
Any clues, please?
Thanx in advance!

It's amazing to me how many people continue to use a picture box when they move beyond what it's designed for. Why not just keep a bitmap in memory, and draw it yourself ?

Hi there!
I'm developing an application with C#.NET 2003 and I want to use a web service I just created on the same computer to test it.
What I've done is to add the web reference (called "localhost" as default). Now I want to declare an instance of that service "localhost.Service1 s = new localhost.Service1();"
but the code preprocessor can't see it. When I try to compile it tells me a reference might be missing, but I actually added it.
I tried to create a new project, and it does add it correctly. Why in my application it doesn't? It's a windows form app.
Help, please! 
NOTE: I just observed that localhost namespace is different! How can I change it????

Hello sergestusxx,
I think there is no problem in ur application. Only thing is make sure that how you are adding the web reference.
When you adding web service url in web reference dialog box, botton right corner there you have to mention the proxy namespace Name(suppose ttt), press OK.
go to your code there
ttt.Service1 s = new ttt.Service1();
regards

HI, i've explained my problem earlier - http://codeproject.com/script/comments/forums.asp?forumid=1650&fr=26&select=1320834#xx1320834xx.
Here it's briefly. i have an assembly that is put there:
http://195.234.68.210/Test/index.html
http://195.234.68.210/Test/ImageEditor.dll
I add the code group to the "Runtime security policy" node in .Net configuration 1.1 applet
like it's discussed here:
http://www.developer.com/security/article.php/11580_3483866_1
But my applet still requests for the permissions: UIPermission, WebPermission
while it was already added.
This page will be given to many users - and i will probably need to give them deployment package or whatever. but still i can't tune this to fun on 1 pc
How should I trust this assembly?
Thanks for help.
I'm also ruzzled-duzzled. in the exception box it's shown PublicKeyToken=b77a5c561934e089 failed.

Hi All,
From my system, I want to stop / start the IIS of different machine and that machine may be on different domain. I have written the following code, it works for my system and it does not work for othe system. It would be great help if you can give some idea.
private bool IISReset(bool start, string machineName)
{
string arguments = string.Empty;
if (start == true) arguments = machineName + " /start";
else arguments = machineName + " /stop";
try
{
//setting the password
System.Security.SecureString pw = new System.Security.SecureString();
char ch1 = 'm';
pw.AppendChar(ch1);
ch1 = 'd';
pw.AppendChar(ch1);
ch1 = 'm';
pw.AppendChar(ch1);
ch1 = 'f';
pw.AppendChar(ch1);
ch1 = 't';
pw.AppendChar(ch1);
ch1 = '@';
pw.AppendChar(ch1);
ch1 = '1';
pw.AppendChar(ch1);
ch1 = '2';
pw.AppendChar(ch1);
ch1 = '3';
pw.AppendChar(ch1);
string domain = "MyDomain";
Process process = Process.Start("iisreset", arguments, "maaz", pw, domain);
process.WaitForExit();
return true;
}
catch (System.Exception ex)
{
return false;
}
}

How can you stop other machine's IIS? This is not possible unless until you are able to run this code on the desired machine.
|
|
|
|
|
IISReset command supports to stop/start the IIS which is running on other system. We have tried it on the same network, but there is some problem when we tried to stop/start IIS on different domain.
It is our project requirement, we have to upload some files and before that we have to stop that IIS.

Does anyone here happen to know of any code that will shorten a path stored in a string?
I have found tons of examples using a StringFormatter that all seem to be centered around drawing the the text using GDI+ but I am not interested in that right now. I don't want to roll my own label control at this point, just try to put a long path into one 
I will have to build one myself I guess...
(unless some nice person happens to know where one is by the time I get home )

Hello,
I've written a reflection app. When I run it on some machines it issues a method invocation error. After some checking I've discovered that the problem is that the Windows EventLog is "full."
But I don't care about the event log and I have zero code that refers to it. How do I tell my app to disregard the eventlog? Is there a global setting somewhere?
Thanks in advance!
