Just suggestion:
Maybe you should consider wrapper ActiveX Control that you insert into your ActiveX Container, that will wrap .NET control methods according to your container rules and delegates calls to .Net control, while converting arguments from VARIANT* to default types expected by .Net control...

Unfortunately I do not. But maybe one of the two will be able to help you if they happen to drop by this forum.

I have a problem with NumericUpDown, they are set to increment and decrement by 2. It does not seem to accept the first click. I have a function SetNumberGrid which draws a number of controls, and works fine.
However the NumericUpDown does not except the first click and then it becomes corrupted so (if nCols = 1)
when 1 is shown 3 controls are drawn, when 3 is shown 1 control is drawn, when 5 is shown 3 controls are drawn, 7 = 5 controls, 9 = 7 controls and so on.
the NumericUpDown control is initialised to 1.
System::Void HeightUpDown_ValueChanged(System::Object * sender, System::EventArgs * e)
{
int nCols = 1;
//get number of columns already visible
if(this->m_numTextBoxArray != 0)
{
nCols = this->m_numTextBoxArray->GetUpperBound(1)+1;
}
//draw controls
this->SetNumberGrid(Int32::Parse(this->HeightUpDown->Text), nCols);
}

|

I think i've worked out the problem, the Text held in the NumericUpDown control must not change until after this event.

Greetings All!
My question is (i think pretty straight forward) mainly about logging errors from a web services or a webform.
What I would like to do is write to the event log from a web service and/or webform. I have read some of the articles on codeproject on how to do this.. but achieved zero success .. Can anyone help?
To further explain what I want to do..
An example web method :
[WebMethod]
public void someMethod()
{
try
{
// soem random code that might throw and exception
}
catch(Exception e)
{
// write to event log here
}
}
This is just one example.. There are more ofcourse.. But again if anyone can shed some light on this subject it would be greatly appreciated!
Regards,
Daniel Rodriguez

When debugging a serial app I'm working on, I notice that every so often a call to WriteFile with a handle corresponding to a serial port blocks indefinately...
After hunting this down I added a healthy write interval timeout and now the call returns (without completing the expected output fully), but after calling ClearCommError() I get no errors
returned, but the condition persists..
Representative calls below:
<br />
hComm = CreateFile(PortText, GENERIC_READ|GENERIC_WRITE,<br />
0, 0, OPEN_EXISTING, FILE_FLAG_NO_BUFFERING, 0);<br />
<br />
SetCommTimeouts(hComm, &MyTimeouts);<br />
...
<br />
<br />
WriteFile((HANDLE)hComm, Buffer, Size, &BytesWritten,<br />
(LPOVERLAPPED)NULL);<br />
Now with the write interval timeout, I check BytesWritten with OutputSize (passed in) and can see when the problem occurs (they don't match), but still have no clue as to why...
Any Resonable suggestions would be greatly appreciated. Thanks in advance.

Hi,
I am using the PageSetupDialog, and all documentation says the Margin units are in 100ths of an Inch. However, the dialog box displays the margin values in either Millimeters or Inches depending on the setting in Control Panel - Regional Options - Numbers - Measurement system.
When the PageSetupDialog box is displayed, the values passed for the margins are converted to Inches, regardless of the 'Measurement system' selected in the control panel. This all works if you select 'U.S.' as your measurement system, but selecting 'Metric' causes the margin values to be corrupted when the PageSetupDialog box is used.
Try it yourself - select 'Metric' in the control panel setting, then use a .NET application that has a PageSetupDialog in it and simply open and close the dialog repeatedly. You will notice that the margin values will slowly decrese until they reach the minimum allowed values. Try setting them higher and repeat the open/close thing.
Shouldn't the PageSetupDialog be using the RegionInfo.CurrentRegion settings to decide on the measurement system instead of the control panel setting???
Is there a way to work around this?
Thanks for any help.

I've been using the colour (Color) structure and noticed you can get the Hue, Saturation and Brightness elements using GetHue() etc. However there does not been anyway to convert a HSB colour back to RGB.
Is there any other class (which I can't find) that can do this?
If there isn't then I have an algorithm to do RGB to HSB, but does anyone know what value GetHue() returns when the Hue value is undefined?
Thanks

Not that I know of. I wrote my own.

You mean when it's grayscale? I don't know, but you might want to experiment to find out.

You know, the folks at SharpDevelop came across this, too. It's due to incompatible graphics card/drivers. Updating your graphics card drivers may help.

I have just found a significant issue with this running on the v1.1 framework (in my enviroment - no others tested). In a nutshell, the Downloader component is starting to scavenge one level too high in the root of the disk drive; this results in some very unpleasant things such as the removal of the entire C: drive on the develoment machine...
I haven't found the cause of the problem yet, but thought I'd put a post out in case anyone else gets caught out. Note that the whole app. was running on the v1.0 framework everything was OK.

I'm trying to use the following:
System.Diagnostics.Process.Start("\\Path\\To\\My\\Program\\blah.exe");
but I get this error when I try to build:
The type or namespace name 'Process' does not exist in the class or namespace 'System.Diagnostics' (are you missing an assembly reference?)
Any idea what I'm doing wrong? Should I be doing this differently? This app is intended to run on a PocketPC, I'm using Visual C# .NET 2003 to create it.

May be you haven't add reference to assembly System.dll?

The Process class is not supported by the .NET Compact Framework!

I am a Software Engineer with two years experience. I am attending night school in pursuit of my graduate degree in Software Engineering and was contemplating studying for the MCSD. Would I benefit in the job market with the MCSD or is this a big waste of time? Also, if anyone is a MCSD, I would really like your book recommendation.
