Hi
I have created a ListView, with View put to Details.
Added a few items, and gave them some subItems.
Then I changed the background colour on all the
items and subItems.

Then when I click on one item it the background on the
first subitem gets gray, and the other subitems get
a white background.

Is it possible to make all the subitems the same colour,
when the item is selected?

Thanks

In the properties for the ListView control you will see a property named "FullRowSelect". Set this property to true.

Print the contents of an entire form

Is it possible to print your entire form, with pictureboxes etc.

I know you can use ControlPaint.Button etc to print my controls, but what if i had an entire form(not mainmenu and the things above) i wished to output to my printer?

Have you tried searching for print form[^]?

Yes but those examples doesnt really do what i want, it has shortcomings when it comes to pictureboxes etc.

In old vb6.0 you could print an entire form, with PrintForm. MSDN makes an example where they Screenshot the memory for the drawed form(since printform isnt in .net), but if some part of the form is outside the screen, it cant dump that.

To me it sound logically, that you should be able to extract the drawed form somehow, even though it isnt on screen. Perhaps build a shadow of it in memory? and then memcpy that to the printerdocument.

You could probably have a look at the WM_PRINT and WM_PRINTCLIENT apis. If I remember correctly they nearly did the same thing as WM_PAINT did with the difference not having an invalid area (i.e. outside of the screen).

Hi
I have created a new Project in VS2003, and added a WindowsForm.
I want the to forms to "communicate". When i call from one to another
I usually create:
public static string/bool/int/etc.
But i want it to do it to:
public static void.

I have done it like this,
public static void Hello()
{
HelloWorld();
}
Where the HelloWorld get data from "private void HelloWorld()"
But that does not work it gives me the error:
'SkoleTing.MainForm.XmlData' denotes a 'field' where a 'class' was expected

I have no clue what I can use instead of the "static", because it is obvious
that I cannot use "static" in this case?

Can anyone help me how to do this?

Thanks

Maybe anyone knows how can I do it?

Thanks!

To do this without a lot of time spent on interop code, you're going to need v2.0 because it exposes permissions and access control inside .NET. Check out this page for reference.

WebBrowser control

Good day.

My name is Eugene.

I have a problem with WebBrowser control from .NET FrameWork 2.0 in my project.

My project (C#) is Form with WebBrowser control on it.
I'm loading in WebBrowser other project (ActiveX Document DLL from Visual Studio 6.0):

webBrowser1.navigate("C:\\Test.vbd");

Next, I'm receive the event:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (webBrowser1.Document != null)
{
// trying get public properties of "Test.vbd" project
}
}

All it's well, but webBrowser1.Document property always equal null.
Although the page loaded correct and event is raising, I can't get access
to the "Test.vbd" interface.

When I use old WebBrowser control (from Visual Studio 6.0) in my C# project,
I get access to "Test.vbd" interface with "pDisp" parameter of event:

void objBrowser_DocumentComplete(object sender, AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
{
SHDocVw.IWebBrowser2 pIBrowser = (SHDocVw.IWebBrowser2)e.pDisp;
...

Can you help me? How can I use new WebBrowser control to get access to "Test.vbd" interface?

Thank you.

Well, strictly speaking a GUID is a Globally Unique Identifier rather than just a User ID. Of course, you can use them as user IDs, especially if there are many distributed computers generating the IDs because the algorithm used is supposed to guarantee uniqueness.

See: System.Guid.NewGuid[^]

Hi!

First of all you should consider modifying your design!
Can you really tell by heart what textbox67 is used for? I strongly doubt that having 90 textboxes on a single form will produce a practical user interface...

Nevertheless, you can iterate over your Form's Controls collection like this:

foreach (Control c in this.Controls)
{
  if ((c.Name == "textbox47" || c.Name == "textbox83") && textbox77.Text!="")
  {
    c.Hide();
  }
}

Regards,
mav

90 TextBoxes on a single form?!?!?! Are all of these textboxes really related to the purpose of the form, or are you dividing the form up into sections with each section doing something different?

Just my humble opinion, but...
Watch as the mouse pointer goes to the Start button, a click is heard, then Control Panels, and again on Add/Remove Programs... Oh! The carnage, as your app is removed by the users because of a clunky, confusing, yet convoluted interface...

LookupEdit of DevExpress

Hi,

I'm using a LookUpEdit in my XtraGrid, which I connect to a datasource at
runtime. When I select a value from the LookUpEdit, everythings fine, the
selected value is shown in the cell, but when this cell loses its focus, the
cell becomes empty.

When I use a ComboBox which I manually fill at runtime, I do not have this
problem.

Any Ideas on solving this problem? Please help me!

Thanks.

Hmm, well that's pretty much all I do.

1) Set the Properties.DataSource
2) Set the Properties.ValueMember
3) Set the Properties.DisplayMember
4) Set up the Properties.Columns

If the data is missing after you move away, is the lookup dataset being closed?

How can I get the title from a program that is active?

I will develop a program that logs every program that a user have used. For example if someone opens notepad I want to retrieve "Untitled - Notepad"

I'm using .NET 2.0

Thanks!
