Xpelive,
The event you're looking for is Closing. The best way I have found to locate an event handler that is supported by an object is to select it in VS and look at the events list in the Properties pane... (press the lightning bolt button)... you can then select interesting looking ones and press F1 to get help on it!!!

Hi, Friends! Does C# have a string function like CString of C++ ? but the C#' String is too small or I must to inheritance String and write a new class ? thx!
|
|
|
|
|
Well there's the string class/type... which maps to System.String which has pretty much all of the functionality of the MFC CString.
The problem is that it is marked as sealed which means you can't derive a new class from it... you could contain a string object in another class then write your new methods to work with the contained string...
What is it you actually want to do?

Can't you use IndexOfAny()???
e.g.
<br />
string myString = "Hello Dave, how are you today?";<br />
string searchString = "Dave";<br />
<br />
bool isSubstring = (myString.IndexOfAny(searchString)!= -1);<br />
<br />
if(isSubstring)...<br />

Had a look at StringBuilder?
System.Text.StringBuilder
In C++, CString does the job of both System.String and System.Text.StringBuilder.

What size should I use to get an equivalent C struct for the type bool?
i.e.
struct
{
DWORD a;
bool b;
} s;
would be
struct s
{
int a;
// bool a; or char a; or byte a; ?
}
...what's the best way to marshal C bools?

bool is not a C data type. Look at the typedef of it.

unsigned char or int? 
What's more common (VC 6 i guess, if anyone can check)
|
|
|
|

What does it say in the header file? It all depends how that implementation is defining it.

Wish I knew. I deleted VS6 and am not keen on reinstalling it. In any case I'm almost certain it's typedef int bool or typedef enum { false, true } bool.
Either way, it looks like I need a dword size field.

I am writing a utility to help deploy some applications.
This utility is used to check the pre-requisites on a PC before an install will be attempted.
One of these aplications uses MAPI.Session and CDO.Message to recieve emails and send emails via SMTP.
How can I detect if MAPI and CDO are installed on the PC using C#
Thanks for your help

Thanks WiB,
I know what MAPI and CDO are but I am trying to find a way of checking they are installed on a PC.
My current testing since posting the question is this - which seems to be working.
protected void CheckMAPI()
{
try
{
Type objMAPIType = Type.GetTypeFromProgID("MAPI.Session",true);
object objMAPI = Activator.CreateInstance(objMAPIType);
if (objMAPI == null)
{
txtMAPIStatus.Text = "MAPI not installed";
}
else
{
txtMAPIStatus.Text = "MAPI Installed";
}
}
catch (Exception e)
{
txtMAPIStatus.Text = "MAPI not installed";
//MessageBox.Show ("Exception - " + e.Message);
}
}

I am creating a ocx that is a treeview.
I am trying to capture the OnNotify with
NMHDR *phdr = (NMHDR *)lParam;
// Coming from listview?
if( phdr->code == NM_RCLICK )
MessageBox(NULL, "Right click found", "Click", MB_OK);
but i am only getting the calls when the mouse is clicked on the header, same goes for Double click, what am I doing wrong,
any help is really appreciated

I don't understand... looking at your code...
What is "->"????
Why do you have so much multiplication in the code too "*"????
And surely it should be MessageBox.Show("Right Click Found", "Click");
  
Sorry, Only joking ShotGun, but this is the C# forum...

Hi All,
How to read file into a structure? The file is created by VC++ 6.0.
For example:
VC++ Code:
struct MyStruct
{
short a;
int b;
char c[20];
short d;
};
CFile aFile;
...
MyStruct aStrcut;
aStruct.a = 1;
...
aFile.Write(&aStruct, sizeof(MyStruct));
I'd like to read the file into the following struct in C#, how? please advice.
[StructLayout(LayoutKind.Sequential, Pack=1)]
struct MyStruct
{
public short a;
public int b;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst=20)]
public string c;
public short d;
};

I'm kind of new to C#, but would like to make at simple monitoring tool for my internet connection - upload/download.
Is it possible to get acces to the Sent/Received on the "Locale Area Conection Status" - dialog?
It would also be nice if I could get a value for the Sending/Receiving speed.

Yes, thank you very much

Anyone know how to make a control transparent. The TransparentKey property is not available in the control as it is on a form ?

Hi, I'm starting to use Active Directory and I have found many C# examples about the topic but I still cannot find something that helps me setup a development environment for Active Directory
At this point I have a vmware virtual machine running windows 2000 but the Active Directory configuration is causing me some troubles
Anyone knows about a whitepaper or any kind of material that helps me setup a development environment with Active Directory in my laptop?
Thanks
Isaac
