Re: how can I get document name if I know HWND - C# Discussion Boards

9-Jun-09 20:10

with GetWindowText I can take only title

Christian Graus9-Jun-09 20:26

Correct. What do you want to get the 'document name' of ? I mean, a lot of HWNDs point to programs that have no document ( Freecell, for example ).

I know about that, but now I need to take information from adobe reader and MS office
From some applications I can take full document name when process created, but I can't take
when office document opened and from Adobe I can take info just only if in the same time opened
only one document

OK, so your question is meaningless. A HWND does not HAVE a document, at least, it's not guarenteed, so no mechanism is going to exist on that level. You need to work out solutions specific to each program you want to interact with, as they will be unique to those applications.

I can take information from some applications by hooking CreateFile and close handle,
but i thought to find more safely and universal way.

Christian Graus9-Jun-09 21:40

There can't be a universal way, when not every HWND has a document. If they are all MFC MDI apps, then perhaps there's something you could try, but I am certain that Word at least does not use MFC.

I think I' combine managed and unmanaged code by using fileswatcher and hooking
some applications.
Thank you for your opinion.

You're not going to be able to hook the API in managed code. And the FileSystemWatcher will not tell you when an application opens a file.

You simply have no choice but to write interop code for each application you want to interact with.

activex component can't create object on a small exe coded on vb dot net

Thank you for answer.
Now I know what to do. I need to check all opened file and then compare with
target windows title.

Hello,

our coder created an application on vb dot net that opens another exe file with process process.start command, the small exe he coded only checks for credentials and asks you to select the branch you belong to from a list of branches.
the program always showing Activex component can't create object, and all the articles on inet did not help so far, any one got any idea, i could post the code but it's long for a forum

Thanks

Impossible to help based on this. You could check your error log for more info on why the object can't be created.

Is the ActiveX DLL registered inoto GAC? Just check.

ActiveX controls can never be registered in the GAC.

Re: activex component can't create object on a small exe coded on vb dot net

9-Jun-09 19:39

well, he created a log on his small code to say how further it went and it finished okay (that's what i was told), but still it won't work on SOME computers,
what is missing like MDAC or dlls? ocxs?

Christian Graus9-Jun-09 20:29

Re: activex component can't create object on a small exe coded on vb dot net

9-Jun-09 20:29

Well, I would hope you've confirmed the ocx is present and registered.

alonchap9-Jun-09 20:32

Re: activex component can't create object on a small exe coded on vb dot net

9-Jun-09 20:32

HE does not know what OCX , because his small app does not include anything in source

Christian Graus9-Jun-09 20:37

Re: activex component can't create object on a small exe coded on vb dot net

9-Jun-09 20:37

If his app doesn't have a reference to the OCX, how is he calling it ? If you don't know what the OCX is, why does your program require it ?

alonchap9-Jun-09 21:37

Re: activex component can't create object on a small exe coded on vb dot net

9-Jun-09 21:37

There is no OCX inside his code.
Would be best if i could show you the code.

cmd=new SqlCommand("sp_detail",p.con);
cmd.CommandType= CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@p",codes);
DataTable dtResult=new DataTable();
if (cmd.Connection.State!=ConnectionState.Open)
    cmd.Connection.Open();
dtResult.Load((cmd.ExecuteReader(CommandBehavior.CloseConnection)));

codes is a string which contains codes seperated by comma, as 28-2801,28-2802...

Re: pass in parameter from c#

9-Jun-09 19:10

This is a SQL question, really. You're passing the parameter in fine. If you enter your parameter as a variable and run the SQL, does it work then ? Might the issue be your parameter being escaped on the way in ?

the thing is, if i use simpl select statement from c# application every thing works fine as
select * from community where code in ('28-2801','28-2802',...)
but when the store procedure is executed, i got the statement of that from profiler as follows
exec sp_details @p=N'28-2801,28-2802'

while these code exits in database, when i execute this statement from sql, it doesent retrieve a value while if i execute it like this
exec sp_details @p=N'28-2801'
then it returns a rows
with single code it retrieve data, but when passing it seperated by comma nothing is retrieved.
any error there?
