SystemMonitor ActiveX control and custom performance counters - .NET (Core and Framework) Discussion Boards

Hi,
I had developed the Pocket PC application using C#.NET for windows CE English version OS. Now I want to deploy the application in windows CE German version OS.
How to do this. Also I am using SQLCE database.

Smile | :)

I am using System.Management.Managementobjectsearcher in C# to read processor Number. Internally it uses COM objects.

So it gives error that System.Runtime.Interopservices.COMException and error message is Com object is not registerd.

This error comes only in windows98. It works well with 2000,xp,2003 etc...

So tell me how to solve this error..

I think the error message speaks for itself. You're trying to create a COM object (you didn't say which one) that isn't registered on the machine.

Either the .DLL that supplies this object isn't registered properly, or you're assuming that the machine has whatever COM .DLL you need and has it registered, when in fact it doesn't. You could also be trying to create a COM object that doesn't have the version you need installed on the machine.

Hello,

Why is it that oftentimes the SubTypes of my forms/usercontrols in the .csproj file are changed from SubType="Form" or "UserControl" --to-> SubType="Code" ? It's annoying as I need to open the .csproj in a text editor and manually change everything again from "Code" to "Form"/"UserControl"

Thanks for the help!

I have the SystemMonitor ActiveX control on a form and I try to register a custom performance counter.
I expect that after registering the counter with the OS, the user would be able to add it through this System Monitor ActiveX control on the form.
Yet, the Add dialog of this ActiveX does NOT contain the already registered counter.
Does anyone know what might be wrong?
Code snippet follows at the end.
BTW if I have the code that registers the counter in a separate executable, then the ActiveX has my counter. But if they're in one and the same executable, the ActiveX doesn't have it !?!

I have an MFC MDI application in VC++ which is active document server application which allows opening document in container like internet explorer.

Is it possible to create the active document server application using .NET framework and allow to open document in internet explorer?

Any tips on the same will be helpful.

Thanks.

Hello,

I'm trying to use Microsoft Web Browser Control coding on c# (framework 1.1), what is the purpose of the wrapper used tlbimp utility.

1) I've load web page using Navigate method

2) then when i got the document, I’m running thru all the elements and make a "hooks" or register delegates on the events I’ve needed.

When I’m using OnClick event - all is OK,

but in others case ( e.g. OnActivate ) - the error occurred

When I’ve implemented such code using winAPI - the code done the right result.

On my opinion there is an error in .NET Framework, i.e. during implementing COM object wrapper.

Hi Room,
I have a small query.
I have an exe that is linked dynamically to another dll built in the .NET.
Now the exe was built in the VC6.0 environment but later shipped to (built in) to the .NET environment.
Now I have a class that inherits CProgressCtrl in both.
I checked the size of CProgressCtrl calss at runtime in both the exe and the dll and find that class's size in exe is 4 bytes smaller than the one in dll.
Could it be because the different environments both are being built on.
The problem is that the size of CProgressCtrl in the exe and the dll is different by 4 bytes that gives me a null CWnd pointer for my progress bar ctrl in the dll(I pass this pointer from my exe to this dll).
Please anyone suggest as to how do i solve this discrepency.
I think that there is a difference in the definition of the CProgressCtrl class in the "AFXCMN.H" of the VC6.0 anmd VC7.0(.NET) environment.

Hello!
I have a simple code that registers wake up event and executes an application, with CeRunAppEvent:

[System.Runtime.InteropServices.DllImport ("coredll.dll")]
public static extern bool CeRunAppAtEvent(string AppName, int WhichEvent);

bool rv = CeRunAppAtEvent("\\My Programs\\program.exe", NOTIFICATION_EVENT_WAKEUP);

Now I need to check if that event was registered previously, in order to prevent multiple registers of the same thing... but I dont find any useful function.

Note: CeRunAppAtEvent returns true altough actual event is already registered. It will only return false if there is any failure.

I have developed a Compact-Framework compliant .NET control (derived from System.Windows.Forms.Control) and would like to host this control in an HTML document on a Pocket PC. On the desktop, the following HTML code works fine:

<html>
<body>
<p>Hello World Control</p>
</body>

<object id="HelloWorldControl1"
classid="http:HWControl.dll#HWControl.HWControl"
height="500"
width="200" VIEWASTEXT>
</object>

</html>

However, on the Pocket PC, the control is not shown... Is it not possible to host.NETCF controls on Pocket IE?

Greets,

what r the classes of .net for GPRS and how the grps.

ddd

There is no GPRS support, or TAPI support for that matter, built into the .NET Framework BCL. If you really need to use the lower level functions of GPRS, you'll have to write wrapper classes for this yourself.

I want to put my referenced assemblies in a subfolder of \bin .. like \bin\assemblies. My application is in \bin.

By fefault .NET puts my app/assembly in same folder as my referenced assemblies. i use "Local Copy" of all references.

Is there a way to tell .NEt to use other locations?

//Maw

You may try using config file for that.

- ashish

any idea of how to use it?

I'm using THE api(SendMessage or PostMessage) to send a custom message between 2 C# exe's. The called exe is subclassed to listen to the custom message. In the calling exe, I'm trying to pass a string in the 4th parameter. At this stage the 2nd exe is already running. The api call keeps crashing the 2nd exe. Can it be done across exe's or only within the same exe, thanks.

thanks for your apply or provide sample code( the best Laugh | :laugh:

Using SendMessage API to control external app:

have an external application that I need to be able to control. I've tried using SendKeys but due to the obvious limitations of this function the behavior is erratic. I know you can do this using the SendMessage API ( find the handle of the external application's window ，first ) ,but I'm not sure how to do it.

can you provide the sameple code to me ,please?

you are welcome to visit my blog

By trying using SendMessage API i got:

C:\Projecti\test\Form1.cs(77): 'System.Windows.Forms.Control.SendMessage(int, int, int)' is inaccessible due to its protection level

This API is from Platform SDK and i think it doesn't support in C#.

To get handle, you can call GetActiveWindow or FindWindow

I can do it now
I can use FindWindow,GetWindow and SendMessage to send message to a notepad app,just like this:

hWnd1 = FindWindow(null, "Untitled - Notepad");
hWnd2 = GetWindow(hWnd1, GW_CHILD);
sText =this.textBox1.Text;
SendMessage (hWnd2, WM_SETTEXT,sText.Length, sText);

but I don't know how to excute a word app's dictate by another app,help me please ,thank you!

I'm learning to program in C# w/ VisualStudio.NET 2003.
I've just bought a MCAD Certification book (70-316) Kalani.
Just started reading the self-assesment portion:
Here's some questions...

What the heck is the difference between the Framework SDK and VisualStudio.NET??

How do I "practice" working with the Framework SDK, as suggested in the book??

I know I'll get hammered for this Q. but so what...would I know the difference just by looking at the screen?

--thanks

The Framework SDK can be downloaded without buying VS.NET. It comprises everything you need to write programs in C# using a text editor and the command line, or a third party IDE, of which one or two exist ( free ware ).

The difference between what ? The Framework SDK and VS.NET ?

The difference between what ? The Framework SDK and VS.NET ? YES.

The study guide said make sure you practice with BOTH VS.Net and
The Framework SDK.
