Infact, i've just remembered a much more reliable way of stopping your window from minimizing / maximizing / whatever. You can override the message in WndProc:
protected override void WndProc(ref Message m)
{
switch(m.Msg) {
case 0x112:
if(m.WParam == (IntPtr)0xF032 || m.WParam == (IntPtr)0xF020)
m.WParam = (IntPtr)0xF122;
break;
}
base.WndProc(ref m);
}
That should disable any such resizing of your form, whether it be by clicking, shortcuts, or magical powers, of course if you want to maxmimize the form, just take out the first part of the IF statement.
My current favourite word is: Waffle
Cheese is still good though.

That's it!
Thanks 
//edit:
that code doesn't work with win+d. When I press win+m all windows are minimizing and my form is still on the desktop. But when I press win+d all windows hide. But when I click any window on the taskbar (eg. IE, mozilla or any) my form is visible again.
Any idea?
Maybe I should catch event of pressing win+d and restore my form again...?
//edit2:
Option in the taskbar context menu "Show Desktop" affects my form too. It's the same as pressing win + d :/

Same issue here. I'm trying to figure out how to prevent Win+D or "Show Desktop" from working on a specific form. In other words, I need a form that is unhidable.
|
|
|
|

Found it! This will disable minimization and "hiding" for a form by attaching it to the desktop (or progman, technically). Here's the code in C# (should be easy to adapt)
<br />
[DllImport("User32", SetLastError = true)]<br />
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);<br />
<br />
[DllImport("User32", SetLastError = true)]<br />
private static extern bool GetLastInputInfo(ref LASTINPUTINFO plii);<br />
<br />
public static void AttachFormToDesktop(Form frmToAttach)<br />
{<br />
IntPtr desktopHandle = FindWindow("Progman", null);<br />
IntPtr result = SetParent(frmToAttach.Handle, desktopHandle);<br />
}<br />
One problem I've encountered so far, though, is that I can no longer set the TransparencyKey property on a form that's been attached to the desktop.
Hope this helps someone!

If you have set up an association with a particular file type for your application, Windows will pass the file name to it as a command line argument when a file is selected.
In the static void main(string[] args) method for your application, the file name can be referenced using args[0].
If you need to set up the file association programmatically, there is an article here on CodeProject[^] that explains how to do it.

Hi,
I am trying to print my Outlook contacts to a checkelistbox I am trying to get only the Fullname and the phonenumber fields. The code below pops up a message box and give s me the nubmer of the contacts I have.
try
{
Outlook.Application oApp = new Outlook.Application();
// Get the NameSpace information.
Outlook.NameSpace oNS = oApp.GetNamespace("mapi");
// Log on by using a dialog box to choose the profile.
oNS.Logon(System.Reflection.Missing.Value, System.Reflection.Missing.Value, true, true);
// Get the default Contacts folder.
Outlook.MAPIFolder oContacts = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts);
// Get the Items collection from the folder.
Outlook.Items oItems = (Outlook.Items)oContacts.Items;
// Get the first contact item in the Items collection.
//Outlook.ContactItem oCt = (Outlook.ContactItem)oItems.GetLast();
Outlook.MAPIFolder foldercontacts = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts);
Outlook.Items searchFolder = foldercontacts.Items;
int counter = 0;
foreach (Outlook.ContactItem foundContact in searchFolder)
{
counter = counter + 1;
//foundContact.FullName.ToString();
}
MessageBox.Show("You have" + counter + "contacts" );
Any help, to print the contacts to a listBox..
Thanks

Maybe I don't understand what you mean. From what I think you are trying to say, can't you just do a listBox.Items.add(youritem); ?

It's not a task is for my knowledge.
I want to place random image from the project resource to my picturebox.that's it 
|
|
|
|
|
Create an array, and put the images from the project resource in it.
Image[] images = new Image[5]; Then create an object of type System.Random:
Random ran = new Random();
^ These two must be defined outside a method.
Then do the following in your button event handler:
images[0] = Properties.Resources.Image1;
images[1] = Properties.Resources.Image2;
images[2] = Properties.Resources.Image3;
images[3] = Properties.Resources.Image4;
images[4] = Properties.Resources.Image5;
int pic = ran.Next(5);
pictureBox1.Image = images[pic];
And that should do the trick.
Edit: Perhaps it would be better to fill up the array in the form's constructor (usually public Form1()):
public Form1()
{
InitializeComponent();
images[0] = Properties.Resources.Image1;
images[1] = Properties.Resources.Image2;
}

I'm trying to find out how the config file works.
This is how my config file looks like now.
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
<section name="Settingstest.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" />
</sectionGroup>
</configSections>
<userSettings>
<Settingstest.Properties.Settings>
<setting name="SampleText" serializeAs="String">
<value>foo</value>
</setting>
</Settingstest.Properties.Settings>
</userSettings>
</configuration>
The Sampletext is connected to a textbox and the default value shows.
But how do I make if i want to write a new text and save it for the user, and next time I run the program the new value should show up in the textbox?
I've tried with ConfigurationManager to store the new value, but I only get System.NullReferenceException so I do something wrong.

Right click on your project and properties then goto settings. you can create a string there. It's a configuration property. These values are saved to your EXE' exe.config file. you can set to this string you created by doing a
your.projects.namespace.Properties.Settings.Default.YourSettingName = m_YourVariable;
Then to get the value of the settings you created you can do
m_YourVariable = your.projects.namespace.Properties.Settings.Default.YourSettingName;

I am attempting to make a new RichTextBox class (called RTBE) which inherits from RichTextBox. One of the things I want to implement is selection graying, so setting the HideSelection property to false makes selections get a gray BackColor on loss of focus. Because I have to restore the original BackColor in the text, I am wondering if there is a faster way to get/set the SelectionBackColor property so I don't have to go through each character in the selection and obtain the color for that character (through the GUI) using RTB.Select(start, 1) followed by calling RTB.SelectionBackColor. Basically, I am hoping there is a Win API call that can get the backcolor of the text in a RTB without changing the selection. Anyone have some insight? Thanks,
Jeff

Take a look at the EM_GETCHARFORMAT and EM_SETCHARFORMAT message as well as the CHARFORMAT2 struct. They can be used with the RTB to enable some more functionality than what the built-in RTB gives you.
Nevertheless, these messages also work on the current selection.
Regards,
mav

I think what I will end up doing is overriding the OnPaint method, and only call the base.OnPaint when I am not figuring out what the current highlighting is. That way, my RTB doesn't flicker. Am I correct in assuming that the WinAPI calls are faster than those exposed by the RTB? If so, I may still use the SendMessage / PostMessage duo in place of the methods exposed on the control as you suggested. Thanks,
Jeff

I have a legacy DLL written in unmanaged C++ that I need to use in a C# application. I can use it ok, but testing shows we don't get the string information when we catch any exceptions it throws.
It throws a simple TCHAR string exception. example:
throw(_T("My Exception Message."))
We can catch it in C# with the System.Exception class, but the string message is lost. (The Message member is empty.) We tried using a RuntimeWrappedException but that did not catch it.
I can not change the code in the DLL. How can I catch these exceptions and get the string info they contain?

But you can create a C++/CLI assembly that can 1) catch the native exception, 2) Create a managed exception and marshal the message into it 3) throw the managed exception.
|
|
|
|

True. And thanks for your suggestion. But I hope there is a more direct way to accomplish the same thing. Surely the designers of the framework made some provision to catch unmanged exceptions AND get the data they may contain. (Unlike the RuntimeWrappedException.)

I prefer to count on C++ rather than hope, but proceed as you like.

I prefer to use the best method available. I am not yet convinced that yours is the best method. It will work, but it is very inefficient.

Compared to what? It is currently your only known solution so it is the most efficient solution.
