Well, I sorted that out using the value of the reg key as [ProgramFilesFolder][Manufacturer]\[ProductName]\App.exe
This points to the right folder and the app works fine normally, but when it trys to launch on startup the Just-in-Time debugger window pops up saying there is a System.IO.DirectoryNotFound exception.
It seems to be looking in C:\Documents and Settings\Mike_Godber\img\Icon.ico for an icon that uses the relative path img\Icon.ico in my code. Not sure why it looks in that folder though as it should be C:\Program files\...\img\Icon.ico.
When I launch the app from Run using the same path as in the registry the app runs fine.
Any ideas why?

Oh, and I have just noticed that I haven't sorted the initial problem out. I still need a way to enter the reg key based on what ever directory the user chooses to install to, but I don't know how to get this value.

I have a windows service and I am trying to instantiate an instance of MAPI:
MAPI.SessionClass objSession = new SessionClass();
// Logon to the Exchange Server using Internet Mail method and profile
objSession.Logon("****", "****", false, false, 0, true, "****";
objFolder = (MAPI.Folder) objSession.Inbox;
objMessageList = (MAPI.Messages) objFolder.Messages;
//Set filter to get all unread mail
objFilter = (MAPI.MessageFilter) objMessageList.Filter;
objFilter.Unread = true;
objMessage = (MAPI.Message) objMessageList.GetFirst(objFilter);
However, when I look at the debugger during execution, the instantiation of the class does not seem to be working. All of the values only hold
"Session <error: an="" exception="" of="" type:="" {system.runtime.interopservices.comexception}="" occurred=""> System.Object"
I think this has to do with the threading apartment because the service is in MTA but the COM object possibly has to be in STA?
Suggestions would be really appreciated!

The instantiation is okay, CDO returns all values only as System.Object.

Why do you pass Accountname/Passwort and profile info?

The first method call after Logon should work in both modes. For everything else, I would expect CDO to fail, because your identity gets lost with MTA.
When using MAPI in a service, make sure you are running STA and don't use .NET remoting. MAPI/CDO and .NET remoting are not compatible.

Sorry, objects were not being stored as System.Object, they were saying exceptions had occurred (I guess when the debugger attempted to access the code).

* That is what the object requires when it is instantiated? for that matter, it doesn't seem to like
objSession.Logon("myusername", "PASS", false, false, 0, true, "exchange.server.com/myusername");
is having any impact. Its calling it an "invalid argument"

Hrm, that would make sense. Regardless, I will need to send mails from this service, so how is that possible? Surely there must be a workaround?
Thanks for such a thorough response!

There are two possible combinations for Logon.
1. Use this one, if there is a profile configured locally for the account
session.Logon(name, password, false, true, 0, false, Missing.Value);
2. Use this one for a dynamic profile, if there is no local Outlook profile configured for this account:
session.Logon(Missing.Value, Missing.Value, false, true, 0, false, "serverName\raccountName");
The second call takes only server name and account name. It uses the service's current impersonation for authentication, so the service have to run with the mailbox owner's account (or impersonate it before logon, and undo impersonation after logon).
I don't know of any workaround for the MTA issue, but CDO works alright, if you don't use .NET remoting. You could open a socket and wait for requests from the client application. Serialize the mail content through the socket, and then send the mails.
You'll need the following classes:
- System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
- System.Net.Sockets.Socket
- your own mail content structure
Client:
1. fill a mail content structure
2. open a client socket
3. serialize the mail content through the socket
4. wait for success response
Service:
1. open a server socket
2. listen for incoming connections
3. accept connection
4. deserialize mail content
5. send mail (CDO)
6. send response (socket)
7. back to 2.

Hi folks,
I currently have to interop to an old ActiveX control that requires the STA threading model. In order to get the control to work, I have to use STAThreadAttribute on the Main method of my desktop application, and set my ASP.NET application to be ASP compatible.
This has impact on the threading of the rest of the application which is undesirable (especially on the ASP.NET application).
Is there any way to load the ActiveX into a separate STA threaded AppDomain, and keep the main AppDomain MTA? I haven't been able to find any examples or explanations for this.
We need to have considerable interaction with the ActiveX control throughout the rest of our code, and I don't know the impact of cross-AppDomain calls on performance, but I can't test until I find out how to separate the AppDomains.
Any interop/threading guru's out there?
PS. We can't rewrite the Activex control as it is third party (and has been discontinued). It contains complex mathematical parsing that we need to maintain for backward compatability.

ok, I have an app that I don't want to to have the blue bar across the top, but I need a way that the user can move the form. how is this done? (I want them to be able to click, hold, and drag anywhere on the form where another control is not covering it).
thanks in advance,
Stephen

You obviously need to capture the click event, and as the mouse is moved, move your window. In C++, it was ::SetWindowPos, if C# does not have an equivelant, you can just import that function into C#.

I do that in this article. All you need to look at is the form event handler code.

I have a reg. expression to search for strings between the "<" and ">" tags. but how do I change the color of all the matches to blue?
|
|
|
|

There are few different ways you can do this (as always), you could use the Regex.Split, go through and call Replace on all the matched values with your corresponding value (blue for you) and then use String.Join to put it all back together.

Yes, but most web pages use cascading style sheets to specify colour. You must grep for '

The problem is that, 'most', is not inclusive, nor was my response. I was only offering a suggestion on how he might attempt it - there are many possible solutions. Thanks for pointing out that the colors could also be defined within a css file, just as well they could be inlined with the HTML in a <style> tag.

hai everybody,
i used the following code to cast an item from the hashtable. but i always get an exception that is an invalid casting.
<br />
foreach (Object objActiveObject in _breathObjectHash)<br />
{<br />
ActiveObjectsInLevel tmpObject = (ActiveObjectsInLevel) objActiveObject;<br />
ActiveObjectsInLevel myXml = new ActiveObjectsInLevel(tmpObject.Row,tmpObject.Column,tmpObject.ExistingObjects);<br />
myObject.SetValue(myXml,count);<br />
count++;<br />
}
please help me

Have you tried this?
<br />
foreach (Object objActiveObject in _breathObjectHash)<br />
{<br />
if( objActiveObject is ActiveObjectsInLevel )<br />
{<br />
ActiveObjectsInLevel tmpObject = (ActiveObjectsInLevel) objActiveObject;<br />
ActiveObjectsInLevel myXml = new ActiveObjectsInLevel(tmpObject.Row,tmpObject.Column,tmpObject.ExistingObjects);<br />
myObject.SetValue(myXml,count);<br />
count++;<br />
}<br />
else<br />
{<br />
Console.WriteLine( "Wrong Type: " + objActiveObject.GetType().ToString() );<br />
}<br />
}<br />

hai Corinna John,
thanks for your comment.i tried the above.but always that else part only works so i triedthe following code and succeed.
foreach (Object objActiveObject in _breathObjectHash)
{
int index = objActiveObject.GetHashCode();
ActiveObjectsInLevel tmpObject = (ActiveObjectsInLevel) _breathObjectHash[index];
ActiveObjectsInLevel myXml = new ActiveObjectsInLevel(tmpObject.ObjectKey, tmpObject.Row,tmpObject.Column,tmpObject.ExistingObjects);
myObject.SetValue(myXml,count);
count++;
}

Hi
In user32.dll there is a function called LockWorkStation.
Is there an complement to it??
Or is there any comparable in msgina.dll?
thx
|
|
|
|
|
|
Stefan, I think he wasn't searching for an equivalent, but for a complement 
I guess there's no reverse function to unlock the workstation.
Platform SDK states:
"This function has the same result as pressing Ctrl+Alt+Del and clicking Lock Workstation. To unlock the workstation, the user must log in."
Besides, what would be the point of LockWorkStation if you could unlock it programmatically?

If, by "complement", you mean is there a function to unlock the workstation, no there isn't. The user has to hit Ctrl-Alt-Del and login again. It can't be remotely unlocked for security reasons.

Hello folks,
I have never been in a project where I need to use legacy dll (non COM dll)
I looked at some examples from that I found in codeproject but I still have some question.
Suppose I have the following methods in my dll:
RF *rfOpen( const char *dev, int mode );
int rfTest ( RF *reader, char *namestr, int namesize, char *verstr, int versize );
where RF declared like this:
typedef struct rfreaderstruct RF;
struct rfreaderstruct {
HANDLE fh;
OVERLAPPED in_ov;
OVERLAPPED out_ov;
unsigned char buffer[BUFSIZ]; /* Read buffer */
int bufferPoint; /* Number of bytes used from inBuf */
int bufferCount; /* The number of bytes in inBuf */
char nonCommandBuffer[BUFSIZ];
int nonCommandBufferPoint;
int nonCommandBufferEnd;
int mode;
int requestInProgress;
int requestOutProgress;
int pendingWrite;
int pendingRead;
RFMessage rfmsg;
int responseState;
unsigned int responseDataCount;
RF *next;
};
how can I make them readable in .Net?
Thanks

If you never have to manipulate the members of the RF structure, it's pretty straightforward:
[DllImport("legacy.dll")]
public static extern IntPtr rfOpen( string dev, int mode );
[DllImport("legacy.dll")]
public static extern int rfTest( IntPtr reader, StringBuilder namestr, int namesize, StringBuilder verstr, int versize );For an 'out' string parameter, you should use a StringBuilder. Set the Capacity appropriately and pass that for the namesize parameter.
If you do have to manipulate RF directly, it will be a lot harder.
Stability. What an interesting concept. -- Chris Maunder
