got it. Thanks for your help. I thought that would be easier but it wasn't.
doc.LoadXml(ls_xml);
string sitemapxslFile = MapPath("menu_sitemap.xslt");
string tempfile = MapPath("jte.sitemap");
StringBuilder sb = new StringBuilder();
TextWriter tw = new StringWriter(sb);
XslTransform xsl = new XslTransform();
xsl.Load(sitemapxslFile); //load xsl file
xsl.Transform(doc, null, tw, null); //does transformation
XmlDocument ret = new XmlDocument();
ret.LoadXml(sb.ToString());
ret.Save(tempfile);
Thanks, Jessica

Glad you got it working. Too bad there doesn't seem to be an easier way. I'm not familiar with the Xml web control as I don't do web development, so FWIW, there may be an easier way I'm just not familiar with. If you really do need an easier way, you might want to post this question in the ASP.NET forum.

Firstly, let me set up the semi-complicated setup on my form. Inside the form, I have a tab control. In each tab page, I have placed a separate user control. Inside the user control in question, there are three group boxes that each contain a data-bound datagridview.
Upon entering any of the dgvs, the usercontrol scrolls such that the top of the datagrid occupies the top of the tabpage (except for the bottom one, then it scrolls down so the bottom of that datagrid is at the bottom of the usercontrol). From what I gather, the form is attempting to ensure that the selected datagrid is completely in view to the user. This is confusing the end-user, and I'm looking for a way to have the scrolling of the usercontrol not happen automatically.
Can anyone point me in the right direction, or give me some advice on how I should handle this?

Hello, I’m hoping some of you can help me.
I’ve created a C# Windows Service project whose service main function instantiates a class library that spawns a new thread to create a new process with which to launch osk.exe (the Windows on-screen keyboard). The purpose for creating this service is to have the on-screen keyboard appear immediately after startup (before the login screen) on a system that will have no keyboard hardware.
I had first built a test program (C# console application) to call the class library and test its functionality and it worked fine. Then I created the Service Project including its installer classes and installed the service with installutil. [Incidentally, all three projects—the class library that launches the osk in a new thread, the test console application, and the windows service—are in the same solution.]
Each time I manually start the service (using the MMC snap-in) I get the following message:
" The service <name> on Local Computer started and then stopped. Some services stop automatically if they have no work to do…"
I don’t understand what this means. The class library contains the necessary start and stop methods, and I copied the same code from the test program to the OnStart () method of the service class. Can anyone please help?
|

Is your stop method being called? If so, where is it called from?
|
|
|
|

Judah, Thanks for responding.
In the OnStop() method of my ServiceBase derived class (which I call OSKStarterService) there is a call to the Stop method of the class library (which I call OSKStarter) that was instantiated. But at this point it's not being called since it's not getting past a successful start.
I'm finding this message in the event log:
Service cannot be started. System.IO.FileNotFoundException: Could not load file or assembly 'OSKStarter, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
File name: 'OSKStarter, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'
at MyNamespace..OSKStarterService.OnStart(String[] args)
at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)
WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
What could this mean? In my service project I had created a project reference from Visual Studio 2005 to the project containing the class library that starts the new thread and osk process, and this automatically created a project dependency. I tried using ildasm to look at the assembly manifest for my service executable but it's telling me: ERROR: Failed to open meta data. Any ideas?
|
|

|
|
So it sounds like OSKStarter library isn't found on the system. As a temporary diagnostic, what happens if you add the OSKStarter dll to the .NET global assembly cache (GAC)?
|
|
|
|
|
Thanks, Judah
In my ignorance, I assumed that the referenced dll would be packaged in the same executable as the service application. The service is now starting and stopping successfully, and I've set it to start automatically.
However, if I log off the on-screen keyboard disappears. Upon re-logging in the task manager tells me the OSKStarterService is still running but the osk.exe application that was started by the service is not.
A post elsewhere suggested the problem may lie with the application being tied to the wrong WinStation. But I don't fully understand what this is about. Any ideas?

I'm afraid not, I've only written maybe 2 windows services in my lifetime; don't really have an in-depth knowledge there.

No problem, Judah. I appreciate your help.
Turns out I found a solution…(with the help of Dean Fiala at strongcoders.com)
It appears the process of logging off kills any non-service type processes, even though it was spawned by a service which is still running. Now I’m having the service poll the running process at regular intervals to see if the osk was exited by other than the service itself, and if so restart it. The only strange behavior is that after the login the keyboard is no longer visible although the task manager verifies that both the service and the osk is running. I’m wondering if this could be a WinStation issue. Regardless, this is not a concern for us since after the login, the system will be running only touch screen applications.

Hi,
I am a beginner in C# and I don't understand the answers in the internet for my question.
I want to catch a picture from my WebCam (USB Port) and show it in a pictureBox for example.
I have the Microsoft Visual C# express edition, that's it and I know how to put a jpg or bmp in the pictureBox but how can I get the Picture ?
Is there anybody who can help me ?

Have you looked at this article[^]? It details how to use the Windows Image Acquisition service to acquire images from a web cam and use them in C#.
|
|
|
|
|
Thank you, but when I start the WebCamServiceSample, it says: connection to the remote server is not possible. What does this mean ?
|
|
|
|
|
Is it WIA? If so, a link from a few months ago on my blog might help you. It's directed at capturing images from a scanner. However, it uses the WIA SDK so if your webcam is WIA all you should need to do is change a few settings (e.g. the device type).

Well, first of all, this is the C# forum. You might have better luck in the C++ forum. Second of all I turned up this after a quick google search. http://www.schneier.com/blowfish-download.html[^]
Never having worked with it, I'm afraid I can't be much more help than that. HTH.

Hello i have something like this:
This Method call me a form and disable the main menu so you can not call another form until you finish the one that you have active.
private void tiendasToolStripMenuItem_Click(object sender, EventArgs e)
{
frmTienda Tienda = new frmTienda();
Tienda.MdiParent = this;
Tienda.Show();
Tienda.Visible = true;
//Here I'm Trying to handel the closing event so to be able to disable the main form(menu)
Tienda.FormClosed +=new FormClosedEventHandler(Tienda_FormClosed);
menuStrip1.Enabled = false;
}
//This is my method where i try to handel the "decision" that you want or not to close the form.
private void Tienda_FormClosed(object sender, EventArgs e)
{
DialogResult r = MessageBox.Show("Seguro desea Cerrar esta ventana?", "Tienda", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
Form f = (Form)sender;
if(r == DialogResult.Yes){
menuStrip1.Enabled = true;
return;
}
}
The thing is that i event i select No as a answer that i dont want to close the form it close anyway, so i would like another way to do it, eather disable the forms behind, or to take the answer of the messagebox so when i select no the form does not get close.

If you want your form to not close when the No button is clicked, add an event handler to the Closing event instead of the Closed event. Your code would look like this:
Tienda.FormClosinng += new FormClosingEventHandler(Tienda_FormClosed);
...
private void Tienda_FormClosing(object sender, FormClosingEventArgs)
{
DialogResult result = MessageBox.Show("Seguro desea Cerrar esta ventana?", "Tienda", MessageBoxButtons.YesNo, MessageBoxIcon.Information);
if(result == DialogResult.No)
{
e.Cancel = true;
}
}

If I understand your question, It sounds like you want your form to behave as a modal dialog. I think what you want is "Tienda.ShowDialog()". Then you don't really need to disable/enable your menu or other forms. In your FormClosing event you can show your message box and if the user answers "No", set e.Cancel to true in your FormClosingEventArgs parameter. Any buttons you place on your form can be assigned a DialogResult property.

Certainly not in this forum, which is the C# language forum. At the very least, you'll need to be in the C++ forum.

 Hello...Iam working in C# .NET and I use a webbrowser control. I already follow all instructions about references, but when the webbrowser is created, look like if everything goes ok, but, the webbrowser don't have good behavior. There are some errors in properties that are not create very well. I can see in WATCH window the errors
Example:
property HWND <error: an="" exception="" of="" type:="" {system.runtime.interopservices.comexception}="" occurred="">
property Resizable <error: an="" exception="" of="" type:="" {system.notimplementedexception}="" occurred=""> bool
Please, I need help.
Thanks

Maite, this really isn't enough information; what error occurs? What do you mean by "the webbrowser doesn't have good behavior"? What behavior is it exhibiting?

Hello Judah...Thanks so much for your quick answer. Here I explain better.
I want to open a word document from my application. I searched in internet and I found a solution and I follow the steps from the site:
http://support.microsoft.com/kb/304662
Everything goes ok, but want a try to show the toolbar, show an exception and the toolbar is not show. I debbug the code and the unique bad that I found is the objet axWebBrowser1 when I made the View in the WATCH Window, there some properties that thrown exception: HDNW, Resizable, etc.
I think that could be there exception for that reason
Here is the code for open ans show toolbar:
//open the document in the webbrowser.
axWebBrowser1.Navigate(strFileName, ref refmissing, ref refmissing, ref refmissing, ref refmissing);
//show the toolbar
axWebBrowser1.ExecWB(SHDocVw.OLECMDID.OLECMDID_HIDETOOLBARS, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER, ref refmissing, ref refmissing);
The behavior that I see after all is that the first time, the right click for the document is ok, but when I go to another application and come back, the right click is not available and the buttons availables doesn't work.
Please, let me know if you have any idea to fix the error.
Thanks so much
Maite
