Hi to all,
In windows forms application, I have simple button and one ContextMenuStrip. I set, then, ContextMemuStrip property of the button to that particular ContextMenuStrip.
When I right-click on my button during program executions, nothing happens.
How to make CMS to pop-up when I click the button?
|

|

If your ContextMenuStrip doesn't have any items it will not show.
To get it to pop-up when clicking (left click..?) you can do the following :
private void button1_Click(object sender, EventArgs e)
{
contextMenuStrip1.Show(Cursor.Position.X, Cursor.Position.Y);
}
A dogged, arrogant belief in self and the childlike idealism that comes with not knowing my limits. This is my greatest blessing, my priceless attribute.

in another form i have only the combo box which has loaded with the category data.
when i select any category i need all the emails belongs to this category should come with a .csv file..
am stuck in " how to seperate emailid's as per the category and how to bundle it and make a .csv file at run time ... ?Confused

Hi Lee,
I think you have to pass category Id in the DB and get all the emailid regarding that category.Like you have selected category "IT Dept" and its id is 2(CategoryId) then pass it to DB and collect result in DataTable
select email from tablename where categoryid = 2
Now you have all the email id in the DataTable.
I hope you can now export this data to the .csv file 
Hope this will help you.
Regards

Hi
As you know a csv[^] file is a text box with coma separated values in it, so all you have to do is to get your data from database, join values of each row separated with a coma into a string and insert the string to a text file and save it.

An eventing service (Project server event handler) is running on windows 2003 server. This service is running under the user "Network Service". This eventing service triggers event handlers against certain events performed on Microsoft Project. The problem occurs when my event handler tries launching an application under the user different than "Network Service". Following is the source code using which i try launching console application under the user which is a domain admin.
public override void onpublish(PSContextInfo ps, ProjectPostPublishEventArgs e)
{
SecureString ssPwd = new SecureString();
foreach ( char c in "password" )
ssPwd.Append(c);
Process myProcess = new Process();
myProcess.StartInfo.FileName = @"C:\test\test\bin\release\test.exe";
myProcess.StartInfo.Domain = "myDomain";
myProcess.StartInfo.User = "domainAdmin"; // domain administrator
myProcess.StartInfo.Password = ssPwd;
myProcess.StartInfo.UseShellExecute = false;
myProcess.Start();
}
Fails in launching executable stating "The Application failed to initialize properly(0xc0000142). Click on OK to terminate the application"
If I comment out the source lines, those specifying the username,domain and password, the executable is launched successfully, but under the user "Network Service". (Like i mentioned earlier the project server's eventing service is running under "Network Service" user) But that doesn't fulfill my requirement. It seems the windows service running under the lower credentials cannot launch the process with higher credentials. I've searched a lot with the problem with no result yet . 
Any one please help into this ....

Hi guys.
How can we access to a textbox in other programs ?
For example , I wanna access to a textbox in Firefox and change the content of it.
Is it possible with API and C#?
Is there a sample of it ?
Thank you
|
|
|
|

Do you even know what API means ?
Yes, if you can get the window handle of the textbox, you can interact with it. You'll essentially be using C++ tho, even if you do it via p/invoke.

Ya. That is P-Invoke. Check this[^] to see if somebody has already done what you are looking for.

I haven't tried, but if you have the other program's handle, SendMessage[^] function can be used.

I use a PrintDialog to set up printer and page setting. I select 'PDFCreator' as printer, and then open 'property'->'Advance' page to select paper size. The wierd thing is, if I select standard paper size('A4', 'A2' .etc), the paper size setting can be remembered correctly next time I show the PrintDialog; but if I choose 'Postscript custom page size' and input custom paper size, this paper setting can not remembered. The next time I show the PrintDialog, the paper size setting is changed to 'A4'. I wonder if any one knows what's the problem. Thanks.

Hi all!
I'm trying to create a program that automates some web activity. The form has a few input controls and a WebBrowser control. When the automation is run I would like the WebBrowser control to show what the automation is doing. However, when I try and create a second thread to do the work (using the WebBrowser control on the main form) I receive errors for unsafe threading. Okay, no problem. When I create the WebBrowser control within my second thread, I receive an exception because the WebBrowser control needs to be attached to a form. When I try and attach the WebBrowser control that was created in my second thread to my main form, I again receive unsafe threading errors...
I have searched all over for an example that uses threading and a WebBrowser control, with no luck. Can someone point me in the right direction or give a hit as to how I can make this work (while still only having one form)?
Thank you!

Hi,
All Controls, including WebBrowser, need to be handled by a single thread; the thread that creates a Control is the only one allowed to call its methods and properties; since all Controls somehow are interconnected in a normal app, they all belong to the main or GUI thread.
Other threads wanting access need to use Control.InvokeRequired and Control.Invoke;
look them up on CP or google for details.

Adding to what Luc said,
Anticast wrote: When I create the WebBrowser control within my second thread
Let the control be on the main thread. Your worker thread can tell main thread to update the control when required. See this[^] article which explains about Invoke/BeginInvoke to avoid cross thread communication errors.
If you are using .NET 2.0 or above, you have one more choice which is SynchronizationContext[^] class.

Thank you both! The way you two explained it made me realize "what I was missing."
In case this will help anyone else, I got my multithreading web automation to work by creating a new Form inside my void Run(); method, then attaching a new WebBrowser to it, and using that WebBrowser to perform my automatioins.
_WBForm = new Form();
_WBForm.Size = new System.Drawing.Size(410, 310);
_WBForm.Visible = false;
_WBForm.Resize += new EventHandler(_WBForm_Resize);
_WB = new WebBrowser();
_WBForm.Controls.Add(_WB);
_WB.Location = new System.Drawing.Point(5, 5);
_WB.Size = new System.Drawing.Size(400, 300);
While this didn't allow me to view the WebBrowser on my main form, it does allow me to actually multithread my search requests by having multiple webbrowser objects. I added a property to allow me to view what the thread was doing if I wanted to:
public bool ShowBrowser
{
get
{
if(_WBForm != null && _WBForm.Visible)
return true;
else
return false;
}
set
{
if (_WBForm != null)
{
if(value)
_WBForm.Show();
else
_WBForm.Hide();
}
}
}
Thanks again all!
