Even though all of your projects are in the same solution
My project dependency question relates to situations where the projects are not even in the same solution. Say for example Projects A, B, and C all have there own solution; from the example I gave, Project A would need to add a reference to both Projects B and C, even though it doesn't use any of the classes provided by Project C.

Garbage collection now handles circular references better.
Apologies if I wasn't clear in my original post, but my circular dependency problem is one relating also to projects: Project A (producing A.exe) requires a class in Project B (producing B.dll), but Project B requires a class in Project A. Neither project will build until a reference can be added to the other  In C++ I can do this with a forward reference, but C# doesn't seem to support this.

I'm having the same problem with circular references describes above. Two DLLs that reference each other so neither one can compile without the other already being compiled. Could you elaborate on your solution a bit?

I´ve an instance of a class that is shared among more than one thread. I need this thread to wait (I mean wait, not sleep inside an infinite loop) until a specific property of this object changes (something like a waitforsingleobject). Does anyone know how can I do this in c# ?

hi Mauricio,
check out Thread.Join method.

Not extacly what I want... this method will just wait till the thread ends. What I´m trying to accomplish is this:
MyObject = new MyClass();
MyObject.SomeProperty = "XYZ";
while(<here I need something to suspend this thread until
the "SomeProperty" of the class instance changes">);
{
// Do some processing here
}
Any ideas ?

You could just use .Net's equivalent for WaitForSingleObject(), something like:
MyClass MyObject = new MyClass();<br />
<br />
MyObject.SomeProperty = "XYZ";<br />
<br />
Thread thrSomeThread = new Thread(new ThreadStart(ThreadRunner));<br />
thrSomeThread.Start();<br />
<br />
lock(MyObject)<br />
{<br />
Monitor.Wait(MyObject);
}<br />
<br />
public void ThreadRunner()<br />
{<br />
}
public int SomeProperty<br />
{<br />
set<br />
{<br />
m_iProperty = SomeProperty;<br />
<br />
lock(MyObject)<br />
{<br />
Monitor.Pulse(MyObject);
}<br />
}<br />
}
A bit simplified, but that's the jist of it.
Cheers

that should work... but...
I don´t have any control over the thread that modifys the property.

In xp prof window when we click start->Run then run window(with title Run) appears
is there any way in a program that this window appears programatically ?
if it is an exe file where is it?
so that i could start it like a process.

To make the window appear programmatically, you need to add reference to shell32 dll in the system32 directory to your c# project.
Once this is done, you create an instance of shellclass and call
the FileRun method.
The code looks like this
<br />
ShellClass obj = new ShellClass();<br />
obj.FileRun();<br />
Hope this helps.
Cheers

You could write a dialog box that does the same thing, basically prompting the user for the name of the exe/program, and then passing the information to ShellExecute or CreateProcess (WIN32 API). If you are using C#, then you could use Process class.

Hello ,
I am trying to pring crystal report without openning a window with the crystal report itself.
I succeeded to print crystal report without parameters by doing:
ReportDocument report = new ReportDocument();
report.Load@"G:\Reports\Rp3Reciept.rpt");
report.PrintOptions.PrinterName = @"\\HPLaserJ5";
report.PrintOptions.PrinterDuplex = PrinterDuplex.Default;
report.PrintToPrinter(1,false,1,1);
and it is working good , but how can I send parameters to reportDocument.
or How can I print report from CrystalReportViewer(becuase to it I can send parameters).
(the printReport() method is virtual , that meens I have to write it?!)
Thank you very much for any answer.

You will need to use an object called ParameterFieldDefinitions. It's a collection of the parameters on your report. Here is a simple little function that you may be able to use. It takes a string for the parameter name and in integer for the parameter value. Of course, you could overload this function for other parameter types, but it demonstrates how to set a parameter value on a report. Crystal could certainly make this process easier than they do.
public void SetParameterValue(string szParamName, int iValue)
{
ParameterFieldDefinitions paramFlds = report.DataDefinition.ParameterFields;
ParameterFieldDefinition paramFld = paramFlds[szParamName];
ParameterDiscreteValue discreteValue = new ParameterDiscreteValue();
ParameterValues paramValues = paramFld.CurrentValues;
paramValues.Clear();
discreteValue.Value = iValue;
paramValues.Add(discreteValue);
paramFld.ApplyCurrentValues(paramValues);
}

Thank you for this , but I still don't know how can I
print this report with its parameters.
ok, let say i made collection of parameters, how can i connect it to the report in order to print the report without preview?
maybe with ReportDocument or some other object?
Thank u anyway, sharon

In your original message you indicated that you were able to print to the printer; with a report that had no parameters. Your code is correct there; you assign the PrinterName property and then call the PrintToPrinter method. If there are parameters you need to pass and/or database connection information you need to set for your report to print, you simply must set those properties before you call the PrintToPrinter method. All of these methods and properties are within the ReportDocument object. So the code would be something like the following:
public class Form1 : System.Windows.Forms.Form
{
ReportDocument m_PrintJob;
public Form1()
{
try
{
m_PrintJob = new ReportDocument();
m_PrintJob.Load("C:/MyReport.rpt");
if (m_PrintJob.IsLoaded)
{
SetConnectionInfo("MyDBServer", "MyDBName", "MyUserName", "MyPassword");
SetParameterValue("ParameterName", 100);
m_PrintJob.PrintToPrinter(1, false, 0, 0);
}
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
public void SetConnectionInfo(string szServer, string szDatabase, string szUser, string szPassword)
{
TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
Tables CrTables = m_PrintJob.Database.Tables;
for (int iIndex = 0; iIndex < CrTables.Count; iIndex++)
{
crtableLogoninfo.ConnectionInfo.ServerName = szServer;
crtableLogoninfo.ConnectionInfo.DatabaseName = szDatabase;
crtableLogoninfo.ConnectionInfo.UserID = szUser;
crtableLogoninfo.ConnectionInfo.Password = szPassword;
Table CrTable = CrTables[iIndex];
CrTable.ApplyLogOnInfo(crtableLogoninfo);
}
}
public void SetParameterValue(string szParamName, int iValue)
{
ParameterFieldDefinitions paramFlds = m_PrintJob.DataDefinition.ParameterFields;
ParameterFieldDefinition paramFld = paramFlds[szParamName];
ParameterDiscreteValue discreteValue = new ParameterDiscreteValue();
ParameterValues paramValues = paramFld.CurrentValues;
paramValues.Clear();
discreteValue.Value = iValue;
paramValues.Add(discreteValue);
paramFld.ApplyCurrentValues(paramValues);
}
}

it seems You must use windows messages, like WM_DEVICECHANGE but I don't know
how do that ....
So can You help me ?
Thanks !
|
|

I have found the solution:
example for devicechange and resolution change:
protected override void WndProc( ref Message m)
{
base.WndProc(ref m);
switch(m.Msg)
{
case (int)Utils.WindowsMessages.WM_DEVICECHANGE:
MessageBox.Show("DEVICECHANGE !");
switch((int)m.WParam)
{
case (int)Utils.WindowsMessages.DBT_DEVICEARRIVAL:
MessageBox.Show("CD INSERTED !");
break;
// Default
default:
break;
}
break;
case (int)Utils.WindowsMessages.WM_DISPLAYCHANGE:
MessageBox.Show("The resolution have been changed !");
break;
// Default
default:
break;
}
}
Bye !

I have a little problem. I have been hacking together a listview control that will not highlight the icon. I am almost there. I wanted to use SystemColors.HighlightText as the color to highlight the listitem just like everything else does. It appears that SystemColors.HighlightText is returning White or RGB of (255,255,255). Am I just totally missed something or what?
Anybody know what the RGB is of the standard highlight color?

|

use : SystemColors.Highlight
thats the bg color (usually dark blue)

This must be so basic a need that everyone knows it, yet I cannot find a reference anywhere.
I want to programmatically from C# bring up the 'default" defined web browser and point it at a particular URL.
Can someone point me to a URL with a reference?
Thanks
-Adrian

The default web browser is governed by a registry entry.
I think the registry key is
HKEY_CLASSES_ROOT\http\shell\open\command
so you read the above key and launch the application with the url as a command line argument.
I hope this should work
If you need more information, have a look at the below URL

What I do in Desktop Bob[^] is:
System.Diagnostics.Process.Start(sURL)
But this has some issues I describe at the end of the article.

I have created a service in c#.
And I am executing a Process.Start command in this code ( OF SERVICE PROJECT) .
that command(Process.Start ) is executing sucessfully for local drives but it throws Win32Exception (means There was an error in opening the associated file) at network path. for example path is \\computername\folder1\folder2\some.exe
AND it heapens only with Service type application all other applications are executing any process at network path (i.e \\computername\folder1\folder2\some.exe)successfully with this command(Process.Start).
Can any body tell how will I make my Service to execute any Process at network path?
plzzzzzzz help me?

What context is your service running in?
Perhaps this is a security issue.
