Ohhhhhhhhhhhhh,...
Sorry. I meant to imply that once the application dials a phone number, has a delay (so it can dial extensions) it plays a wav file to the mailbox it dials. So it simply calls an IVR here at the office and leaves someone a voice mail. The wav played is not DTMF but a voice that we choose.

Reply to my own message is what I want.
I want to find the best voice modem out there (but it is ok to have some short comings as it seems there is no clear winner). What are your thoughts as per voice modems? I'm not concerned over flash-hangups (line switch) but mainly want to be able to send wav's to a modem to play after dialing and navigating through an IVR. So I can conquer the initial menu navigation with delays in the ATD command but after that simply need to leave a message (internal alert type system from server).
any recommendations on the optimal voice modem?

in a child thread i'm calling folderbrowsing dialog , i get the exceptiuon and , i got some articles saying i must use STAThreadAttribute attribute for the main method , i did that and the result was the same
"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process."
i tried
inthrd.SetApartmentState(System.Threading.ApartmentState.STA); too but still the same result. can any one have any idea about this.
thanx in advance.

I don't know all the details, however here are some facts:
1. you can set the apartment state only once;
2. IIRC you can't set it at all on ThreadPool threads;
3. I don't recall what happens if you try and ignore #1 or #2.
4. the easiest way to solve such problems most often is to do all user interaction on the main (aka GUI) thread.
BTW: when referring to some error message or exception you should paste it verbatim in your question.

thanks,actually what i'm doing is creating a new window in the child thread, so in that window i want to open this folderbrowsingdialog, so at that point i get the exception.
and following is the exception i got
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process.
thanks in advance.

thanks again . i found the issue , i'm using a separate class for creating threads in the application , and i had set the
l_thrd.SetApartmentState(ApartmentState.STA); out side that class , when i moved this line into that thread creating class i got my problem solved. but i really don't know difference the two places i used the code
thankx .

It is generally a bad idea to create UI on child threads, particularly if those threads are doing any data processing. The modal stack for different threads is separated, so (for example) message boxes and dialogs from a child thread won't interact as you expect with the main thread. A modal dialog is better than normal forms because you don't need to add a message pump to the thread but it's still not recommended in most situations. (For example, what if two threads want to ask the same question at the same time?) Have you thought about why you want to do this?
|

It is always a best practise to limit your user interaction to the main GUI thread. Modal windows are modal only to the thread they're created on and not modal to the entire process as one would expect.

Hi guys,
I've searched google but didn't find anything regarding this issue. I'm updating an MS Access table after reading some fields from the same table. While doing this i have a label to check how many rows have been processed out of total and i see that the reader jumps from an ID to another, process a few rows then comes back to the ID before jump happened. Is this thing normal?
The table is created from an imported text file using Access.Application.DoCmd.TransferText. I thought compacting the database after import will fix this, but didn't. Any ideas?
Thank you!

IMO a database is not supposed to obey a specific order, unless you specify one. Ultimately if you don't specify an order, the results could be different each time. I always specify an order before the user gets to see the data, so he shouldn't get any surprises here.

It just didn't cross my mind to order by ID.
Thanks!

Give a chance for the author to atleast look at it.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Are there any genius way to make Display and value member object related to the object in the combobox?
As you can see in the following code, I'm using IEnumrable of Email objects to add into the combobox, and the Email are an entity object related to the LinQ (.dbml) object mapped from the database (which means each object itself contains value fields from the database).
comboBox_n1.Items.Clear();
comboBox_n1.Items.AddRange(_controller.getEmailList().ToArray<Email>());
comboBox_n1.Sorted = true;
comboBox_n1.SelectedIndex = -1;
Right now it shows an object string like: 'MyApp.Email' for each object in the list.
Before now, I have made a ToString() in the .dbml code, for each object which ofcause works, but it ain't a sustainable solution since it will dissapear each time I made a change to the datamapper.
So are there any way to auto generate these display members??

Hi,
You can put your ToString() method in a separate file, making use of the 'partial' keyword in the class declaration.
So, when you regenerate your model, your separate file won't be impacted by the changes, therefore your tweak will still work.
Hope this helps.
Regards.

Thanks, that will work for sure.
But it still feels like some kind of 'hack' in the structure. Ain't there any official way to do it, like 'click here and choose which data field to be shown as display member', for non-DataSources (like generic lists)??

No, there is no "offical" way to do it. Based on your requirements, the suggestion given is the best one to go with. Use a Partial class and put the code that cannot change into a seperate file.

Just realized that I've never used the partial function before, so I'm not sure how to attack it. Could you gief an example plz?
I have a CRUD (Create, Read, Update, Delete) class for handeling all the email specific methods like:
public Email GetAllEmails(){}
The Email class is within the DataClass Datacontext, and thats the one who is getting regenerated each time I have a db scheme change.
Could you give an example of how to make this partial class for a ToString() for the Email class?
Here is a short outtake of the CD (Class Diagram): http://imageshack.us/photo/my-images/36/classdiagram.jpg/

Simple. It's a class that get split into multiple files. One of them has to have the normal class definition. The others all continue the class code inside a partial class definition.
C# Partial Class[^]

Hi,
Sorry for this late reply but I was on vacation these days.
First, you have to make sure that generated classes are all defined with partial keyword.
For example :
public partial class DataClass
{
public partial class Email
{
}
}
Then, just add a Whatever.cs file to your project :
public partial class DataClass
{
public partial class Email
{
public override string ToString()
{
}
}
}
You could also define an extension method for you Email class : just add an Extensions.cs file to your project and define an extension method to the Email class.
public static class Extensions
{
public static string ToString(this Email email)
{
}
}
Hope this helps. Kindly.

Hi,
We have an issue - how to pass .net (C#) string to unmanaged C++ dll?
We tried something, but this error came up:
"An unhandled exception of type 'System.AccessViolationException' occurred in mscorlib.dll
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
Does anybody know how to do this? We need the code sample.
Thank you in advance.
