I have parent and a child form. When the child form is shown, I want it to appear in the middle of the parent form. If I set the Location property before I call Show() on the child form, the location will not be what I specified. If I set the location after I've called Show(), then for a fraction of a second I can see the form showing up at its default location and then it very quickly moves to the location I specified. This is now very professional looking I would like to avoid it. How can I do that? Why doesn't it work to set the Location property before calling Show()? Thanks in advance for any help!

Try changing the StartPosition of the form to CenterParent instead of changing its location property
Intelligence is almost useless for those who have nothing else!

This code works if you want to do it from the parent as you asked. It may be better if ammended an placed in the child form's Load methd (after InitializeComponent()).
Form2 form2 = new Form2();
form2.MdiParent = this;
form2.Location = new Point(
this.ClientRectangle.Width / 2 - form2.Width / 2,
this.ClientRectangle.Height / 2 - form2.Height / 2);
form2.Show();
DaveBTW, in software, hope and pray is not a viable strategy. (Luc Pattyn)Expect everything to be hard and then enjoy the things that come easy. (code-frog)

if you have a MDI parent from then just set the startposition of your child form to centerparent as mentioned by other guy.
not sure if it works with non MDI parent form or not

If I set StartPosition to FormStartPosition.Manual then the location is determined by the Location property and it work great even if I set the Location property before I call Show(). Thanks y'all for your tips and suggestions.

Hi,
I am running this code from my local machine to get information from a remote machine i.e. strRemoteMachine which I have admin rights on.
Do you know why I get Access Denied on oResults.Get() //???????
Thanks
ManagementScope myScope = new ManagementScope(strRemoteMachine + "\\root\\cimv2");
SelectQuery oQuery = new SelectQuery("SELECT * FROM WIN32_Printer");
ManagementObjectSearcher oResults = new ManagementObjectSearcher(myScope, oQuery);
//Iterate through printers...
foreach (coItem in oResults.Get()) //???????????
{
string strPrinterName = oItem.Properties["DeviceID"].Value.ToString();
}

First, your scope path should be in the form
@"\\machinename\root\cimv2"
If you still get denied access, you'll need to use the ManagementScope
constructor that takes a ConnectionOptions, in which you'll pass valid
credentials.

Hi,
Yes, I am using credentials now as below but I still get the Access Denied error:
Any thoughts please?
string strWapiServer = "\\\\mywapiServerName";
string strPrintServer = Environment.MachineName;
ConnectionOptions options = new ConnectionOptions();
options.Impersonation = ImpersonationLevel.Impersonate;
options.EnablePrivileges = true;
options.Username = "myDomainName\\username";
options.Password = "password";
ManagementScope myScope = new ManagementScope(strWapiServer + "\\root\\cimv2", options);
SelectQuery oQuery = new SelectQuery("SELECT * FROM WIN32_Printer");
ManagementObjectSearcher oResults = new ManagementObjectSearcher(myScope, oQuery);
//Iterate through printers...
foreach (ManagementObject oItem in oResults.Get())
{
string strPrinterName = oItem.Properties["DeviceID"].Value.ToString();
}

Hi,
So, do you mean:
for accessing a 64 bit machine, I can still use select * from win32_printers ? even though it points to win32 ?
I did read the link you sent, thanks but there is nothing there that talks about 64 bit operating systems.
Please note that all the machines with 32 bit system, I can access but not the 64 bit systems. They all have the same operating system.
And I am admin on all of them. So the only issue is to access the 64 bit systems.
Any thoughts please?
Thanks

I never said anything about that. win32_printer is the WMI class name -
it has nothing to do with 32-bit/64-bit.
All the same reasons for access denied (security) should apply to 64-bit
OSs.
It doesn't matter if you're an admin on all of them - they have to be configured
to allow remote administration.

How do I configure to allow remote administration?
Thanks

I gave you a link that worked for me - there's a LOT of pages of
information starting at that link.
I'm a programmer not an IT person, sorry. 
Since you're getting access denied, you're already getting
past firewall/routing issues, so that's a start.
What operating system is running on the remote?
FWIW, your code worked fine for me just setting the
ConnectionOptions object as follows:
ConnectionOptions options = new ConnectionOptions();<br />
options.Username = "username";<br />
options.Password = "password";<br />
options.Authority = "NTLMDOMAIN:myDomainName";
Maybe Kerberos authentication will work for you...

Operating system on teh remote server is:
windows server 2003 SP2 64 bit
Do you know how to implement Kerberos into the above code?
Thanks

|

I added the options.Authority = "NTLMDOMAIN:myDomainName";
as you suggested.
It still says, Access denied.

NTLM is the default authentication method so you shouldn't need
that line.
This is most likely security configuration issue so throwing code at it
isn't going to help - if you could get past security with code it
wouldn't be too effective
Make sure you've done this on the remote machine:
Enable WMI (Windows Management Instrumentation)[^]
Also, take a look in the registry on the remote machine.
If there's a key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\forceguest
and it's set to 1, set it to 0.
You can also test using the Computer Management WMI Control snap-in.
Run "wmimgmt.msc", right click on the WMI Control and choose "Connect
to another computer". Try to connect to the remote machine. If it's successful
then your code is probably wrong. If it gives you access denied then
you probably have a configuration issue.
That's all I know. You should definitely ask on an IT newsgroup about enabling
remote WMI on Server 2003.

Hello,
THe bit in the registry is 0 already.
Using wmimgmt.msc as you suggested just stays on connecting to windows management as if it hangs.
I will keep on checking other issues if I can think of any...
Thanks anyway...

Hangs connecting to the local machine, remote machine, or both?
Regardless, that's a bad sign - if you can't connect with the tool
designed to do what you're doing, then you can't expect your code
to be able to do it.
Again, ask IT people how to enable remote administration on the OS.
It can't be done with code. There's some good Windows administrator types
on the MSDN newsgroups. I'll post a question to the MVPs and see if I
can get you some info.

The target machine can not be accessed via WMI and it can not access any other machine from it either.
Thanks.

Hello,
I have developped a windows application using c#.net.
Now the owner of the business need to use this application from outside the local intranet. He want to use it as a web Site.
Is it any method to do that or do someone know another method that allow us to access the application through the WEB.
Best Regards
Bye.

Well, you could always deploy it using ClickOnce[^], but I would check very carefully if your architecture would withstand using this application over potentially slow connections (I'm assuming that you have one centralized datastore here).

hello,
i am using an sql Database
is it possible to use the click once feature ??
best regards.

Yes, but you'll have to be careful with regards to database authentication and security.

I have an application with a regular "main" or "parent" System.Windows.Forms.Form. Sometimes, I would like to display a dialog-looking form as a child form to the main main form. I would like the child form to meet these requirements:
1. When the child form is shown, no additional task is shown in the taskbar on the lower part of my screen.
2. When the child form is shown, it becomes impossible to access any controls on the main form. Basically, the main form can't be activated when the child form is shown.
3. When making the call to show the child form, the calling thread does NOT get blocked.
4. The child form can easily be moved anywhere on the screen, even outside of the main.
5. The child form is ALWAYS in front of the parent form.
How can I accomplish this? I am most grateful for any suggestions.
