One of the features stopping us migrating to C# from VC++ is the limited windows form styles. In a VC++ dialog box we can set the dialog box to have no borders and pop-up style.
I cant seem to find a way setting a windowsform to have no border in C#/MC++, I wonder if this is possible at all?
many thanks

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
You can set it through the properties or in code as above, valid styles are:
Fixed3D :A fixed, three-dimensional border.
FixedDialog : A thick, fixed dialog-style border.
FixedSingle : A fixed, single line border.
FixedToolWindow : A tool window border that is not resizable.
None " No border.
Sizable : A resizable border. (Default)
SizableToolWindow : A resizable tool window border.

Hi Gurus,
I got some kind of unusual program to do...
I am viewing a web page in Internet Explorer 6.0, and I got a flash object in that page. So, I want to ask you if it's technically possible to write program that will send onclick message to the Internet Explorer window? And if it does can you give me some help how to do this thing, please. Or maybe some links would be helpful too...Thanx.

Yes, you can P/Invoke SendMessage and pass the BN_CLICKED message. You will need to the HWND (handle) of the button itself for the SendMessage call as well. You can programmatically iterate through each window using FindWindow. Spy++ may also be of some help to you depending on specific implementation.

Thanx for your answer...Could you please give me some links or code samples
of SendMessage, HWND and FindWindow usage? Or some articles would be helpfull...

Reading MSDN[^] will be very helpful. In particular, SendMessage is documented here[^], however because it is a native method, you will need to use P/Invoke to gain access to it. Reading about the DllImportAttribute Class[^] will be helpful. Also, you can read about P/Invoke here[^]. In .NET, a HWND or handle is of data type IntPtr. The SendMessage declaration should look like this:
[DllImport("user32.dll")]
static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam,
IntPtr lParam);

Hi,
I have an application for which I must create a Setup package. The package allows the user to enter some information in a text box (during the installation). I have used Textboxes(A) for this purpose. The textbox must contain a default value when presented to the user during the installation. This default value must be set dynamically. Is there some way this can be done... maybe the Setup Package reading an ini file and putting the value from the file into the text box during the installation?
I don't know if and how ini files can be read during the installation.

You set the EditNProperty to a property name, typically upper case (so it can be changed on the command-line as a protected property, though, IIRC, VS.NET doesn't use this (it's very limited in functionality when it comes to Windows Installer packages). You can set the initial value using EditNValue.
After compiling the MSI package, you can also use Orca from the Windows Installer SDK (go to http://msdn.microsoft.com/platformsdk[^] to download it, though Orca is a separate install within the downloaded files; in the bin directory, install Orca.msi) to add that same property name to the Property table with the initial value.

I already have used the Edit1Property and have set it to "URL". What I need is to be able to fill the Edit1Value dynamically, read from a text file maybe, and be displayed to the user.

You have to write a custom action for that, and writing a .NET Installer class derivative won't work. You must write a native custom action (see the Windows Installer SDK for details), and VS.NET does not support that.
It can be read from the command-line, though, if you use something like this:
msiexec.exe /i MyPackage.msi URL=http: I suggest you read through the Windows Installer SDK.
The VS.NET Windows Installer project is very limited, as I mentioned before. Trust me - I've been working with Windows Installer since 1.0 beta many years ago and have been a consultant for numerous companies for Windows Installer-related development. VS.NET's Installer project is meant to be quick and simple and does not expose a UI for a majority of what's possible.

No. Your rewriting an application. It's up to you to figure out the requirements, design and build. You already have a tempate to work from if you have the PowerBuilder source.

I use MDI form in my C# project,
each MDI child form has a PictureBox on it,
When I load my saved project,
I use
myPicture.PictureBox.Image = Image.FromFile(path);
to set the image show on PictureBox.
But in my project sometimes I need to insert a new Page,
so I write
<br />
for(int i=Page_number-1; i>IntSelectPage; i--)<br />
{<br />
((MyInkPicture)myAL[i]).PictureBox.Image = ((MyInkPicture)myAL[i-1]).PictureBox.Image;<br />
} <br />
to show the correct image of each page,
Now there is a big problem,
When I want to save my changes,
<br />
PictureBox.Image.Save(savepath,System.Drawing.Imaging.ImageFormat.Bmp);<br />
for example,
because original PictureBox[2]'s image now is PictureBox[3]'s image,
if I want to save image by "Picture2.bmp",
it would tell me "Picture2.bmp" is in use...I can't overwrite it!!
Can anyone tell me how to load a picture form a set file path,
and if the image changes, I can overwrite it...??
Thanks a lot !!

Clone the original image then dispose it so that you have a copy of the image, not an image from a file (which uses an open file handle, leaving the file in use):
using (Image img = Image.FromFile(path))
myPicture.PictureBox.Image = (Image)img.Clone(); The using statement here makes sure that the object is disposed when the block is complete, even in cases when an exception is thrown.
Also - just a suggestion - I'd recommend you encapsulate myPicture.PictureBox.Image, exposing the Image property on your class by defining it like so:
public System.Drawing.Image Image
{
get { return PictureBox.Image; }
set { PictureBox.Image = value; }
}This ensures that callers can directly modify your PictureBox control. This makes for a better object-oriented design.

I add two TextBoxes snd a checkbox to a panel, each time I click on the add button. Each have a unique name. I can add them fine, I need to remove them according to the checkbox's checked property. I first need to know whether a checkbox is selected, then I need to traverse all the checkboxes and if they are seleted, I need to remove the corresponding texboxes.
I use:
if(this.pnl1.Controls.Contains(CheckBox))
{
// how to check each checkbox
}
Help!

I just tried to solve the problem logically. May be you get some better solution.
for(int i =0; i < this.Controls.Count; i++)
{
if(this.Controls[i].GetType().ToString() == "System.Windows.Forms.CheckBox")
{
MessageBox.Show(Controls[i].Name);
}
}
Do revert back whether it solves your purpose or not.
Regards,
Jay.

Thanx bro..
I'll try this later, if you don't mind.
But it looks like it might work. thnx 'gain.

Or even shorter, without string comparison and getting the cast from Control to CheckBox for free:
foreach (Control c in this.pnl1.Controls)
{
CheckBox cb = c as CheckBox;
if (cb != null)
{
MessageBox.Show("Checkbox "+cb.Name+" checked: "+cb.Checked);
}
}

But here CheckBox cb variable is created for each round of execution of the loop. I do not know whether this can be said as more optimized.
Regards,
Jay

Ok, you can take the CheckBox cb and put it outside the loop if that's your only concern... 
Or you yould use
if (c is CheckBox)
{
CheckBox cb = c as CheckBox;
}
I found the is keyword very handy instead of fiddling with GetType().ToString() and then comparing to the quite verbose (and thus prone to typos) fully qualified type names.

I am writing an application to change the inputlanguage and culture using C#. I am trying to find out whether selected language is written left-to-right or right-to-left to set right-to-left property of my control accordingly. Is there any way to find this ? Please Help!!

Can anyone tell me is there any difference between the usual DOS Command Prompt and the Visual Studio.NET Command Prompt provided with the Visual studio.NET?
Can I run a C# Console application which takes Command line arugent from the Visul Studio itself without using the Command Prompt?
Thanx.....
|
|
|
|
|
The Visual Studio .NET Command Prompt just sets up the paths to all the VS and .NET tools.
Go to normal command prompt and try an run "csc" or "guidgen" if they're not in your path, they won't run. Inthe VS.NET command prompt they will. And yes you can run console apps from IDE and even pass parameters to it. Check Project->Properties

Thanx Roman
I tried giving command line arguments in Project->Proprties->Configuration Properties->Debugging. It works fine.
If every time I want to give a different value I have to set the value there only.
thnx again.

How can one replicate the Close() event with its corresponding CancelEventArgs?
I.e. how to find out from the code firing the event what the receiver set this attribute to?
Does anyone know and can help clarify this procedure to me...
