You're not going to be able to do this using all-.NET code. I don't know the specifics of how to do it, but you're going to have to basically replace the system's print dialog to do what you want. This is FAR from a trivial task. You'll need very advanced knowledge of Windows internals and COM programming, along with some C++.
Why? Because Windows Security does not have any facilities in it to do what you want. Assigning a seperate password to a resource is a very inefficient method of trying to protect that resource. Personally, I think you're wasting your time trying to do this. Windows Security is made in such a way that users have a single sign-on and don't have to worry about "yet another password" to remember to access any resource. The permissions to users and groups of users are assigned to the user based on their login token, this includes accessing shared devices such as printers.
Your current method does not stop a print job from running. Since the job is already being spooled when your code figures out it is there, the print job has already started happening. The only thing you can do is pause the printer, which pauses ALL print jobs going to it, even the ones by other users who have supposedly put in the proper password. This is easily defeated because the user can just resume the printer to get around your password.

You don't. Services should not expose a user interface.

You can't do that. The next time anyone installs a piece of software or MS releases a patch, it'll overwrite or replace what you put in.
manjari kar wrote: any ways can i customise the print dialog of the system
Again, the answer does not change. I've already given you the list of skills required to replace the dialog AND/OR alter the existing one. This is an extremely advanced topic, not for beginners.

You are entirely on your own with this one. Putting in a username and password is just making things more complicated than they need to be. There is no legit reason to do this and it's easily defeatable. You are doing things that noone does. This is what makes it entirely on your shoulders now...

Then he's going to have to prove it. Doing it in VB6 alone isn't possible. Personally, I think he's blowing smoke out his ass.

</group>
</tab>
</tabs>
</ribbon>
</customUI>
I have also created the callbacks for the OnAction event as such:
<pre>public void OnActionCallback(Office.IRibbonControl control, bool isPressed)
{
if (control.Id == "btnNewVersion_Click")
{
//MessageBox.Show("You clicked " + control.Id);
Form frmNewModel = new Form();
frmNewModel.Show();
}
else
{
MessageBox.Show("You clicked a different control.");
}
}
But i still can't get any functionailty out of it. I have successfully added the ribbon to the workbook as a tab but also have some default menu items displaying even after setting the StratFromScratch property to true.
Please help where you can.
Thanks

G'day all 
I've almost finished working onn a word processor and last night somethin very weird happened. I added a new blank tab to my sexy tab control and saved changes, then I thought I'd give it a rest and turn off the computer. Well, this morning, I switched on and to my surprise, all my combo boxes, buttons (68, to be exact) had all been removed from my toolStrip. Now, The code for each of my controls is still in the code view but the only things missing are the ones inside the toolStrip (tab control is still there).. Has anybody had this problem before? Does Visual Studio have some magical invisible button that I must have unknowingly clicked to remove those controls? Any thoughts on this? I'm mystified...
regards
jay

Hi Jay,
I’ve seen this many times in my own projects but have [Edit!] never found out why. The most common post in internet forums suggests that the reason is the presence of duplicate resource files but that has never been the case in my situation. I always find that the code to add the controls to the toolstrip has been removed by VS and it is a simple matter to edit the designer file to fix this.
A simple example:
Before the error
this.statusStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.Status});
this.statusStrip1.Location = new System.Drawing.Point(0, 636);
this.statusStrip1.Name = "statusStrip1";
this.statusStrip1.Padding = new System.Windows.Forms.Padding(1, 0, 21, 0);
and after the error
this.statusStrip1.Location = new System.Drawing.Point(0, 636);
this.statusStrip1.Name = "statusStrip1";
this.statusStrip1.Padding = new System.Windows.Forms.Padding(1, 0, 21, 0);
I hope the fix is as simple for you and if you do come up with a reason for the error please post back as I'd love to know!
Alan.

Thank you for the reply and code Alan, I'll be trying to figure out why this has happened and will definately post the reason for it if I can figure it out.

I often have a similar problem. All my buttons, comboBoxes, textBoxes, and checkBoxes suddenly disappear, but my groupBoxes and other containers are still there. If I click and drag the select the region containing the buttons, etc. then their outlines all show up. Then I just slightly resize one of them (affects them all since they're all selected) and like magic they all show up. Then I Ctrl+Z the resize and everything's back to normal. Still haven't figured out why this happens. Could be the resource file issue mentioned above, but I haven't really checked.

Never underestimate the power of the backup! I have a scheduled task that runs every couple of hours and copies all my current working project files to a backup directory (it creates a new time-stamped directory each time).
At worst I might lose a couple of hours work, which is a nuisance but not a disaster.
There are three kinds of people in the world - those who can count and those who can't...

Videos provide look into how you can support Windows 7 in your applications.
MSDEV.com[^] has produced a set of videos giving developers a look into Windows 7 coding. You can view the videos in the series main page, A Developer's First Look at Windows 7[^].
This series introduces Windows 7 with an emphasis on those new features that will be of most interest and use to developers. It consists of: two introductory sessions, one focusing on the new user interface, and one on behind-the-scenes features, two hour-long sessions that cover compatibility and security issues, six shorter sessions which focus on coding for a single new feature.
For more information, see See Windows 7 From a Developer Point of View in msdev.com Videos[^].

I have all the code necessary (I think) to perform a drag and drop into word... but I am having trouble with pictures... any kind of Bitmap or Image does not drop properly into word, it does something but then acts as if I didn't drop anything it understood.... However, the same code works for dragging and dropping onto other office apps (e.g. Excel and Powerpoint).
The code looks like this:
<br />
private void pictureBox1_MouseMove(object sender, MouseEventArgs e)<br />
{<br />
if (_mouseIsDown)<br />
{<br />
IDataObject obj = new DataObject(DataFormats.Bitmap, pictureBox1.Image);<br />
this.DoDragDrop(obj, DragDropEffects.All);<br />
}<br />
}<br />
Any one have any idea what I'm doing wrong? (and for the record, I have tried it without using IDataObject as well, just directly putting the image into the data argument... oh and I also tried creating a "new Bitmap(pictureBox1.Image)" and putting that in the data argument...
To no avail....
A) Can anyone reproduce the issue at hand
B) Does anyone know what I'm doing wrong? Do I need to use OLE directly or something?
Thanks

Welp this is as close as I could figure out.
You cannot do it directly in memory (as far as I can tell), but here is the code emulating something close to dragging and dropping a file from explorer into word:
<br />
string[] files = new string[1];<br />
files[0] = @"C:\someimage.jpg";<br />
IDataObject d = new DataObject();<br />
d.SetData(DataFormats.FileDrop, files);<br />
<br />
if (this.DoDragDrop(d, DragDropEffects.Copy) == DragDropEffects.Copy)<br />
{<br />
}<br />
Still cannot figure out why I cannot just drag and drop an image directly though.... would love to know what I could do differently.

Hi All,
Just came across a strange issue recently.
Maybe its a bug in the framework or something ?
I have 2 processes running , each with its own winform UI, say host application and external application. The host application has a user control and a context menu defined for that user control, plus some blank panels. The external application also has a user control and context menu defined on it.
Now lets say do a SetParent across processes(i know, i know but that`s what the applications must do right now), with the host process` panel as the parent handle, and the external application`s user control is made its child window, then the context menu`s show unusual behavior i.e we can have both their context menus visible simultaneously !
I`m using the contextmenustrip class of dot net 2.0 and this issue doesn`t seem to occur for the older 1.1 context menu classes (in the same scenario).
Is this a known issue with the newer 2.0 class ?
Are there any workarounds to rectify this behavior ?
Is there any way I can get to know the context menu started, closed events across processes if required?
Any help is most appreciated.
Thanks in advance.
