Be sure you've assigned an icon to NotifyIcon component. Unlike Forms, there's no default icon for tray icons (so they won't show unless you've assigned one).

I'm attempting to use managed code from unmanaged code using clr hosting.
This works fine but I'm having trouble creating one specific type.
I've gleaned the following values from the HResult, but can't find out exactly what the error code means.
Can anyone help?
hresult = -2146232828
severity = 1
facility = 19
error code = 5636
Thanks in advance!
M.

You seem to be getting a COR_E_TARGETINVOCATION exception. It's not a well documented exception; have a read of this[^].

Thanks for the answer...that was the problem.
Some dependent assemblies were missing from the GAC.

No problem. I'll tell you how I figured it out, so you know what to do next time - I converted the error code into hex using Windows calculator - enter the value in decimal, convert it into decimal and change it to a DWord. I searched for the HResult of that value, in corerror.h. From that point, it was easy to google on the "friendly" name and identify issues with it.

Thanks. I had been wondering how you achieved it, as I once created a tool that calls FormatMessage(), however it did return null/nada/Nothing for this error code.

Hi Guys,
I've got two config files for a winforms app:
app.release.config
app.debug.config
I copy these into the appropriate folders using the following post build event:
if $(ConfigurationName) == Debug copy "$(ProjectDir)app.debug.config" "$(TargetPath).config"
if $(ConfigurationName) == Debug copy "$(ProjectDir)app.debug.config" "$(TargetDir)$(TargetName).vshost.exe.config"
if $(ConfigurationName) == Release copy "$(ProjectDir)app.release.config" "$(TargetPath).config"
if $(ConfigurationName) == Release copy "$(ProjectDir)app.release.config" "$(TargetDir)$(TargetName).vshost.exe.config"
This works if i only build the project, but if i run the project as well, then the files are replaced by the origional app.config.
If i change it to overwrite the app.config file (Either pre / post build):
if $(ConfigurationName) == Debug copy "$(ProjectDir)app.debug.config" "$(ProjectDir)app.config"
if $(ConfigurationName) == Release copy "$(ProjectDir)app.release.config" "$(ProjectDir)app.config"
Then it overwrites the app.config file fine, but doesn't actually copy it to the output directory.
Any thoughts? This should be a common problem that's got a solution right? It's driving me crazy 
Regards
Tris

Anyone ever have an issue with signtool.exe where it freezes up?
I'll run it one minute and it doesn't work, then a few minutes later it works fine. Also, suspiciously Internet Explorer will stop working.
I've already ruled out anti-virus software.

|
|
|
The SignTool can also go out to a website that provides a timestamp. Perhap's you're having internet connection issues?
|
|
|
|

That could be.
Although IE doesn't work Chrome accesses the internet fine. Maybe it's an M$ thing.

Hi,
We need to export the content of a docx file (MS Word 2007) to docx/HTML in sharepoint portal. For this, we are evaluating using System.IO.Packaging library available in .Net 3.5 WindowsBase assembly. We can identify text in the document and export it. However, we are still not finding any easy way out for exporting images, tables, attachments etc. If you have any solution to the problem or working experience with packaging library, please let me know. This is urgent.
Thanks,

I came across some great articles about merging wave files, but unfortunately the wave files I use are imported by the user. Therefore, it is quite likely that one wave file has a different sample rate/bps than the other one. When I try to merge them, Windows Media Player cannot play them, most probably because they have different sample rates/bps. How would I go about making the wave files have the same sample rate/bps as each other, in .NET, so they can be merged properly?
Thanks.

It depends on the quality you want to achieve, and whether you want to do it in real time.
* for very low quality, simple sub-sampling will work
* for medium quality use linear interpolation of samples
* for high quality, use a more complex method such as sinc interpolation
There are some useful resources here...

Judging by the fact that you talk about OnClientClick, I would suggest that you would get better responses if you post your question in the Web Development forum.

Does the .NET version of VC++ compile into native code?

You can use Visual Studio (versions above 6, including C++ Express) to build either Win32 (=Native code) or CLR (=Managed .NET code) applications. Check under menu File/New/Project...

ok thanks. I have both VS6 Enterprise and VS.NET Express. Just not sure which I should go with for my, hopfully, commercial project. I can say VS6 Enterprise.

I'm not sure VS6 runs fine on recent Windows versions (Vista, 7).
Anyway, I decided against it some time ago; why keep it around as newer VS versions can handle the same job?

Hi All,
I hope i am posting in the right forum as i am looking for a .Net related solution rather than a pure XML solution.
I have the following class which i serialise using default XML serialisation.
Class UserA
UserID
UserName
Description
Comments
End Class
Later, my requirements changed and i had to generate 2 views of the same data.
In my 1st view, i would generate XML for the whole object (all 4 properties)
My 2nd view - include only UserID and UserName.
i modified the code as below
Interface iUser
UserID
UserName
End Class
Class UserA
Implements iUser
UserID implements iUser.UserID
UserName implements implements iUser.UserName
Description
Comments
End Class
I intended to serialise appropriate objects (iUser or UserA) based on my view requirements.
Unfortunately, i realised that XML serailisation does not work on interfaces - end to my dreams of getting it easy
My question is - if i have an Object instance, can i use any feature with serialisation to generate multiple views of an object?
I have ventured towards creating seperate classes, ISerializable, etc.
looking for suggestions on whats the best way to take this forward.
Thanks in advance.

It might be worth bearing in mind that you can implement IXmlSerializable in an object and just dump that into the object hierachy you use the automated serializer for (XmlSerializer). The serializer will call the IXmlSerializable instead of using reflection, which means you could do your branching in there.
However, it could be a maintainance time bomb. ^^
