Hi,

I am converting a ContextMenu from an existing app to ContextMenuStrip. I got around the problem of not having a Clone method handy, but I haven't found a way to implement the DefaultItem behavior that came with the old MenuItems.

Any suggestions would be appreciated.

Thanks Smile | :)

open forms of an external application?

Hallo
i need to open some forms of a VB6 application from a .NET one; i have written both, so i have the source code and know the source names of the forms.
What should i do?
Are the forms accessible via their source code names? Eg. in a way like Form1.show etc.
Thanks in advance Smile | :)

The two apps don't know anything about each other. The forms in one are not going to be available to the other at all, let alone by the names you used in the source code.

What are you really trying to do with this?

ok thxalot for your feedback.
the situation is that i have a large VB6 application running, and i'd need to implement new forms/new functions that would be easier to code in .NET, or at least possible only in .NET. But i'd like the user to have the impression to use only one application: i.e. the VB6 app still run in foreground while the .NET runs in background and its forms are shown only when needed, or viceversa or something like that.

If you compile your VB6 application as an ActiveX Exe you can implement a public function in a public class which opens your form.
It should be no problem to convert your project if it isn't already an ActiveX Exe project.
After this you can bind your exe in the .net application and use the class to open the form.

Hi I've been asked to associate a file extension to my program, so that

You should create a registry key. If you're using fw 1.1 you can use the OpenNetCF Library to do this.
Creating a file extension association should then be the same like doing it for windows.

CF 1.0 SP3 - WinCE - FullScreen and Controls.Clear() - Add()

Marco [Stinger]14-Dec-05 2:09

Hi I'm developping a WinCE 5.0 app using VS 2003, C# and CF 1.0 SP3.
I'm currently testing on the WinCE 4.1 Emulator but a quick check on the
CE 5.0 Device confirmed the behaviour.

I create a full screen Form setting:

<br />
ControlBox = False<br />
FormBorderStyle = None<br />
WindowState = Maximmized

I add 3 buttons (button1, button2, button3) and add the following :

private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
this.Controls.Clear();<br />
}<br />
<br />
private void Form1_Click(object sender, System.EventArgs e)<br />
{<br />
this.Controls.Add(button1);<br />
this.Controls.Add(button2);<br />
this.Controls.Add(button3);<br />
this.Refresh();<br />
// this.Invalidate();<br />
// button1.Invalidate();<br />
// button2.Invalidate();<br />
// button3.Invalidate();<br />
<br />
// this.Invalidate();<br />
// button1.Visible = true;<br />
// button2.Visible = true;<br />
// button3.Visible = true;<br />
// button1.BringToFront();<br />
// button2.BringToFront();<br />
// button3.BringToFront();<br />
}<br />

As you see I clear the controls with the first button and then try to
reasign the 2 controls to the form on the OnClick event of the form.
Guess what happens ?
No controls appear on the first clieck, button2 and button3 on the second
click and all of them on the third click.

But there's more:
The controls don't show, but they are there: I click where I remeber the
control was and I get the button.OnClick event !!!!!! OMG | :OMG:

As you see I've tried everithing I know (visible, invalidate, refresh etc
etc) but I allways get the same behaviour.

Do you know how I can get the right behaviour ?

I found a workaround, but I'm still looking for the right solution.
the workaround is:

private void button1_ParentChanged(object sender, System.EventArgs e)<br />
{<br />
(sender as Control).Visible = ((sender as Control).Parent != null);<br />
<br />
}<br />

So the buttons turn invisible after the Controls.Clear() and return visible
after the Controls.Add().

Please note that this is just a TEST APP, the real app must asign
dinamically the controls so Controls.Clear() and Controls.Add() MUST be used

Please Note: if I don't set the FormBorderStyle = None property then
everything works perfectly !!!

WTF | :WTF:

Please help

Ciao

Did you tried to use 'new' :
button1 = new System.Windows.Forms.Button()

Another question: why do you clear them from their parent. You could set them invisible, setting them visible again shoudl work without problem.

I can't test your code, because i've just got Windows CE 4.0.

I don't need to create a new button..it's already there, I just need to
set it's parent.
Visible works but I need to get 'em off the parent form completely

Thanks for the effort

Yes I know that it's there. But if you use the constructor there should be no problem. If there is a problem they way you tried, it sounds a little bit like a bug to me. So I would try something different. Smile | :)

Hello! I need to make some search in the registry...

I need to find all the keys and the values that include some word, and to delete

them... I know there is a class Registry, but I don't know how to do what I need.

Maybe someone could help me?

Thanks!

There are the Registry-Class and the RegistryKey Class

You can get all RegistryKey-Names with a funktion in the RegistryKey-Class:
string[] name = Registry.LocalMachine.GetSubKeyNames();

you can open every subkey and on this you can get all SubKeyNames of this Subkey.

So you can look up every Key, Check its values and if you like Delete it with the Funktion DeleteSubKey

Hey Guys,

Been playing with MSH & WinFX and put together a little MSH script to build all projects on your machine which you may find helpful (especially for building the samples)

MSH> $files = (dir . *.csproj -Recurse)<br />
MSH> foreach ($file in $files) {<br />
 cd $file.Directory.FullName;<br />
 msbuild;<br />
}

60% of statistics are made up on the spot

Can anybody please help me in resolving this Issue?

I am trying to open and save a file saved on my local computer through XmlDocument in a Smart Client Application which accepts the Xml data from a web service in the form of a string, which I update to a file in my local machine.

Following is the code..

RSMService lRSMService = new RSMService();
InputOutput IOComplianceGroup = new InputOutput();

IOComplianceGroup = lRSMService.GetSpecificData("procGetSanitizerLog",IO.propertyDataset.Tables[0].Rows[0]["StoreId"].ToString(),false);

if (IOComplianceGroup.propertyResult == Result.Success)
{
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(IOComplianceGroup.propertyXmlDocument.OuterXml);
System.IO.FileInfo FI = new System.IO.FileInfo(path1);
if(FI.Exists == false)
{
FI.Create();
FI.Open(System.IO.FileMode.OpenOrCreate).Close();
}

FI = null;

try
{

xmlDoc.Save(path1);

xmlDoc = null;

}
catch (Exception ex)
{

MessageBox.Show(ex.Message.ToString());
}

}

Thanks in advance

MD5 checksum test for COM-DLLs

Hello,

I want to calc and test the checksum of an COM-library I use in my project. But as I got as AssemblyLocation only the reference to the Interop-file I don't know how to test the checksum of library itself.
Is there a way to get the reference to the DLL behind an interop resource? Does anybody know?

Thanks,
Ingo

(You've probably found your answer already, but oh well.)

I'm not positive about this (and am too lazy to doublecheck), but I think the wrappers for the COM objecs in the interop assembly will have the CLSID attached to them via attributes. Assuming that, one could then use reflection to grab the CLSID for the COM wrapper being used, then open up the registry key associated with that CLSID and grab the location of the binary.

Example:

For the COM object MyOldCOMObject with CLSID "4C6055D8-84B9-4111-A7D3-6623894EEDB3", the interop assembly should generate something like this class definition:

[Guid("4C6055D8-84B9-4111-A7D3-6623894EEDB3")]
public class MyOldCOMObjectClass : IMyOldCOMObject
{
}

If so, then the registry should have a key like this:

HKEY_CLASSES_ROOT\CLSID\{4C6055D8-84B9-4111-A7D3-6623894EEDB3}\InprocServer32\(Default): C:\MyOldApplication\MyOldCOMServer.exe

-- modified at 0:47 Friday 23rd December, 2005 (CP doesn't seem to like my registry key example, even though preview works.)

VB.Net Excel

Hi From Australia,
I Have a project that acesses an excel file that I have stored in the bin folder of my project. All I do is click a button and it opens excel - this works fine on the development computer but when I try it on other computers (Slightly Older) the file opens but is locked and read only saying that the file is already open. I can find the file through excel on the computer my program is installed on but not from my program. Any Ideas?

I'm confused. Does it open in a "locked and read only " state or is it that you can't find the file from your program? My guess is that your program is referencing one version of the Excel object on your development machine and the production machine has an older version installed. For example you may have Office 2003 installed on your dev machine (I believe its the Excel 11.0 object) while the production machine has Office 2000 (I think it is Excel 9.0 object). Check to see which version of excel is installed on each machine to see if they match.
