Hi,
I have a component in vb.net. In this component i have app.config file from which I am reading the connection settings and settings for enterprise libarary exception handling.
If I use this component form .NET application it works fine but when I try to use this component from asp by registering the dll, the copmponent is not able to read any settings from app.config file.
Please provide solution to this problem i searched everywhere but not able to get the working solution.

To my knowledge a DLL cannot have app.config
because app.config is only for individual applications (like windows / console)
i.e. it should not be a DLL
however a DLL can read ....
for example : 1. sum.dll is reffered in math.exe
2. then sum.dll can read from app.config of math.exe
3. sum.dll cannot have it's own app.config.

Hi, all!
I have a following problem, and i can't find a right solution.
Description:
There is a COM server written on C++ and it works through IDispatch and it does't have a TYPELIB. And from another side there is a COM client developed on C#. Through LATE BINDING it uses a COM server
and COM server sends different events to client, but i can't implement COM event handling mechanism.
Please, anybody can help me?!
Thanks in advance!

If you have a look in the registry below HKEY_CLASSES_ROOT\CLSID\{<clsid of the server>}, does it contain a key named 'TypeLib'?
If not, do you have an .idl file where the interfaces of the server are defined?

maybe you could check whether server app contains typelib using vs2005 ,like wlm.

Hi all,
I am been having trouble with finding an answer to this question but here goes:
Is there any way to write to MSWORD without automation through ASP.NET in C# (maybe write to an existing word document without opening it)?
I am pulling my hair out! I have tried adding IUSR, ASPNET to the web server, I have tried Identity Impersonate = True in the web.config.
My code for opening word looks like this:
object isVisible = true;
object readOnly = true;
I get a Macro storage error on the open statement. I have put a lot of time into figuring this out and I really dont want to do a TOTAL 180.
wordDoc = WordObj.Documents.Open2000(ref fileName, ref missing, ref readOnly, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref isVisible);
I appreciate any ideas or suggestions given!

I have a Local Server created in MFC. It displays a modal dialog with a "logout" button. It also contains a COM coclass "A" to which clients are connected. Everything works fine till all clients follow proper reference count rules.
But if a client terminates abnormally, then this coclass "A" has an outstanding reference count on Local server. When user clicks "logout" button, the application dialog closes but the server continues running in background because of this outstanding reference count.
I understand that when the proxy no longer exists in this case, the stub will do a cleanup automatically but after few minutes.
But the requirement is to force the application to shutdown completely when "logout" button is clicked. I have thought of few ways to do it, but I would like to know your thoughts on this so I can choose the best possible solution.
Thank you for your time.

if you implement _IDTExtensibility2, you could check application name at OnConnection().

Hi
Created a small VB 6.0 ActiveX control Which has an event CallMe. This event is triggered when a button the control is clicked.
Public Event CallMe()
Public Property Let Text(value As String)
txtString.Text = value
End Property
Public Property Get Text() As String
Text = txtString.Text
End Property
Private Sub cmdFireEvent_Click()
RaiseEvent CallMe
End Sub
I have tested it with a VB 6 project and it worked.When i tried to use the control in a web page, events are not getting fired.
Sub myCtrl_CallMe()
MsgBox "yes"
End Sub
<object id="myCtrl"
="" classid="clsid:55F1D62E-0C61-4637-BA76-594B493A0341">
What should be the problem?

Hi
i am trying to change a component code a little bit to display some statusbar messages etc. By the way the component is devoloped in VB so i did a small change initially to the code like changed the cursor style and code to display some status message after that i did "make DLL" then that worked well on registering the newly created dll. But after that i included a single statement to setfocus to someother control and again i did the makedll this time on registering the dll the component is not at all activating so i removed the statement which i included (i.e to setfocus of some control)again i created the new dll using make dll but unfortunately the new dll(which is like the previous worked one ) not activating the component.
What could be the problem why its happening so. Please help me.
Thanks in advance.

In VB project properties, there are some settings for Version compatibility. The GUID must be changing on each compile probably. Please check these settings. Since I haven't worked with VB so this is just a guess. See if this is your problem.

You need to study BHO[^].
|
|
|
|
|
I don't understand ?
pop up blocker ??
can you explain more ? thanks

Link I provided was of search result of BHO on CP. You need to browse through those articles, to find appropriate one.
Read BHO from MSDN,too.

Hello,
I've just tried to handle an OPC-interface with VC++ 6.0
Therefor I create an Instance of the interface to get the a pointer of this interface.
This should be ok,
but...
when I want to get access to the methods of the interface, I always get unknown failure codes back:
Interface Instance:
IOPCBrowseServerAddressSpace* InstantiateOPCBrowseServerAddressSpace(wchar_t ServerName[])
{
HRESULT hr;
CLSID CLSID_OPCServer;
CLSID CLSID_OPCServer2;
void** ppIntfObj = NULL;
// Get GUID and UUID from regsitry for COM-Server
hr = CLSIDFromProgID(ServerName, &CLSID_OPCServer2);
ShowError(hr);
// Queue of Class-Instances to create
LONG cmq = 1; // number of class instances to create
MULTI_QI queue[1] = {{&IID_IOPCBrowseServerAddressSpace,
NULL,
0}};
//Create an instance of the IOPCBrowse
hr = CoCreateInstanceEx(CLSID_OPCServer, NULL, CLSCTX_SERVER, /*&CoServerInfo */ NULL,
cmq, queue);
ShowError(hr);
// Return Pointer to the IOPCBrowse Interface
return(IOPCBrowseServerAddressSpace*) queue[0].pItf;
}
In my main-method, I try to work with the interface,
but I only get two different failures as HRESULT:
0x000006F4 in the first attempt.
and 0xC0000005 in the second and third attempt. (this means here Access Violation?)
Implementation in main-method:
CoInitialize(NULL); //Using MS Com library
//Instanciate Browse-Interface
IOPCBrowseServerAddressSpace *pOPCBrowse2 = InstantiateOPCBrowseServerAddressSpace(L"SOFTING.OPCToolboxDemo_ServerDA");
//Declarations for OPCBrowse
HRESULT hr;
OPCBROWSEDIRECTION dwBrowseDir = OPC_BROWSE_TO;
hr = pOPCBrowse2->ChangeBrowsePosition(dwBrowseDir, NULL);
ShowError(hr);
OPCNAMESPACETYPE *pNameSpaceType;
hr = pOPCBrowse2->QueryOrganization(pNameSpaceType);
ShowError(hr);
OPCBROWSETYPE dwBrowseType = OPC_FLAT;
LPENUMSTRING *pIEnumString;
hr = pOPCBrowse2->BrowseOPCItemIDs(dwBrowseType, NULL /*Filter*/, 0, 0, pIEnumString);
ShowError(hr);
...
Where could be my problem.
The interface is defined in an IDL-Sheet from the OPC-Foundation.
Perhaps you've got an intension, if there is anything wrong with my interface handling or coding?
Thanks for your work at this time
