you didn't really give us much to work with so, what do you expect?
but:
did you try Q183599 in the MSDN "HOWTO: Catch Microsoft Word97 Application Events Using VC++" ?
did you look at: "Automation And Eventing With Microsoft Word" http://www.codeguru.com/atl/wordauto.shtml ?
did you look at: http://www.codeproject.com/com/word_ole_bm.asp ?
how about : http://msdn.microsoft.com/library/en-us/dnguion/html/drgui102599.asp ?

Yes, I have looked at all of these examples and they do not necessarily match the scenario I have now. I am using Automation to call MS Word, next I open a document, then I dynamically add a button to the Word toolbar using the commandbars functions. But none of the above examples will work, since they all use ATL and my application does not. All I am looking for is some knowledge as to how I can capture the event that the button that I dynamically created, not one that is on a dialog box or so forth, was pushed. If it was going to cause this much controversy, I would not have put my post out here. I noticed another person's post, Al_ something or other, having a similar problems. So it isn't just me having problems...
By the way, thank you for the advice but it didn't help...

I'm not sure about this, but I may have an idea that may flukily do what you need (though I'm not sure how efficient or how well it conforms to com standards - it is just an idea). Could you not use a hook procedure to grab 'control' of the apps messages and test to see when your button has been pressed by the message that is sent to the app? Not sure about whether this is even capable, just an idea I thought I might share.

I need to create a wizard to gather information from the userregarding a file.
Currently, I want to use the wizard in two different ways (this may increase in the future)
1. As a standalone wizard
2. As part of a File Open/Save dialog
My dilemma is how to create the wizard.
Should I :
a. Create as a class which is then included in each project where the wizard is required
b. Create as an ATL control which can then be used in any container in the future - even though the wizard is not a simple control e.g. it needs to contain a combo box, edit controls etc. and talk to a database.
c. Create in some other way.
Anyone suggestions are welcome...
Thanks

I'd go for a, which is way simpler than other options. This is how most controls, wizards and other stuff are provided here at CP.

In general it's probably a matter of preference. I would personally create a Static library with the Visual Studio Wizard and put your wizard/DB code in there. Then I would just include that library in whatever project I was using. The reason I choose this method is because I like to statically link things that I have control over. That is just my personal preference, though.
If you have questions about doing what I've suggested, let me know and I'll walk you through it. BTW, did you know that property sheets have a wizard mode? Would accomplish what you are wanting to do pretty easily. Something you may want to look into.

Whilst b is a nice option, it means a lot of extra work without much extra gain (unless a third party app is going to call your wizard).
I'd stick with a, you can always wrap it in a COM object later should the need arise.

Hi all...
i'm trying to list the avalible trays for specifice printer. for that list i use combo box so the user can choose what tray he/she wants the printer to use to print.
so i search and only find setting landscape, paper before the printing.
but i found out about
Devicecapabilities(...) to get avalible tray (Word) array. then i can set the tray by using DEVMODE.dmDefaultSource .
so i code like this
<br />
void CSMPprojectDlg::ListTrays(CWordArray *traysArray)<br />
{<br />
int arrayLength = traysArray->GetSize();<br />
<br />
for(int i=0;i< arrayLength; i++)<br />
{<br />
WORD tray = traysArray->GetAt(i);<br />
m_FolderTrays.InsertString(i,(LPCTSTR)tray);<br />
m_FileTrays.InsertString(i,(LPCTSTR)tray);<br />
m_ErrorTrays.InsertString(i,(LPCTSTR)tray);<br />
}<br />
UpdateData(TRUE);<br />
}<br />
<br />
void CSMPprojectDlg::SetDefaultPrinter()<br />
{<br />
CPrintDialog dlg(FALSE);<br />
dlg.GetDefaults();<br />
defaultPrinter = dlg.GetPrinterDC();<br />
dcPrinter.Attach(defaultPrinter);<br />
<br />
if(theApp.my_DevMode !=NULL)<br />
::GlobalFree(theApp.my_DevMode);<br />
<br />
theApp.my_DevMode = dlg.m_pd.hDevMode;<br />
lp = (LPDEVMODE) ::GlobalLock(theApp.my_DevMode);<br />
ASSERT(lp);<br />
<br />
CString pDevice= dlg.GetDeviceName();
CString pPort= dlg.GetPortName();
LPTSTR pOutput;
if(DeviceCapabilities(pDevice,pPort,DC_BINS, pOutput,lp) != -1)<br />
{<br />
if(pOutput != 0)<br />
{<br />
ListTrays((CWordArray*)pOutput);
}<br />
}<br />
<br />
}<br />
does anyone of you have same problem?
can u give me sample code or link about it.
thanks

I have a file opened with ifstream and I need to get to the top of the file. Right now I close the file, then open it back up again but thats pretty inefficient. For some reason I remember doing file.seekg(0); at school, but that doesnt seem to work.

You might wanna do a file.clear() to clear the state. E.g the eof bit might have been set earlier.

Perfect, thanks

I am currently working on a system that uses an Access database to store a list of url's waiting to be processed. I need to be able to add to, and amend the database, and so, I have derived a class from the CRecordset class called CURLRecordset using the classwizard.
In my application, I can succesfully open a CDatabase object in order to connect to the database, but when it comes to opening the actual recordsets associated with it:
/*
CURLRecordset* unparsed_urls;
CDatabase* db;
CString sql;
*/
unparsed_urls = new ( CUnparsed ) ( db );
sql.Format ( "SELECT * FROM urls WHERE status = %d;", STATUS_NOT_CRAWLED );
unparsed_urls->Open ( CRecordset::snapshot, (LPCTSTR)sql );
I get the following exception:
"Invalid character value for cast specification on column number 2 (urladdress)"
I have traced the source of the exception to the final move() function call in the CRecordset class's Open() method, but I have no idea how to deal with it. My database schema is as follows:
TABLE urls =
(
long urlid (PRIMARY KEY)
VARCHAR(256) urladdress
long status
long level
long keywordid
long sourceid
)
The header file for the CURLRecordset class is as follows:
class CURLRecordset : public CRecordset
{
public:
CURLRecordset(CDatabase* pDatabase = NULL);
DECLARE_DYNAMIC(CURLRecordset)
// Field/Param Data
//{{AFX_FIELD(CURLRecordset, CRecordset)
long m_keywordid;
long m_level;
long m_sourceid;
long m_status;
CString m_urladdress;
long m_urlid;
//}}AFX_FIELD
// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CURLRecordset)
public:
virtual CString GetDefaultConnect(); // Default connection string
virtual CString GetDefaultSQL(); // Default SQL for Recordset
virtual void DoFieldExchange(CFieldExchange* pFX); // RFX support
//}}AFX_VIRTUAL
// Implementation
#ifdef _DEBUG
virtual void AssertValid() const;
virtual void Dump(CDumpContext& dc) const;
#endif
};
Any help will be greatly appreciated!

I think the problem may be in your DoFieldExchange() function...I can't think of anywhere else that the problem could be.

Hi guys, there's a nice article here on CP with a C++ implementation of the Blowfish algorithm for encrypting files. The examples given however are a bit simplistic and I can't seem to get it to encrypt a text file. Has anyone done that yet?

0. initialize the cipher
1. open input file
2. open output file (binary mode)
3. while (you haven't read the whole input file)
3a. get a block of text from the input
3b. encrypt it
3c. write it
4. close both
the last block will probably require padding to the cipher's block size
-c

You mean I should append each encrypted block of text to the output file?

|
|
|

yes.
thought it's not so much "append" as it is "write". "append" implies the file already exists (and is closed) and you're going to add more to it after re-opening it.
but, the idea is to read, encrypt then write one block at a time.

I put an OCX control window. I put an Edit box derived from CEDit. In Edit box, if I press backspace, message will not posted to my active edit box, instead goes to IE. Similarly, Arrow Keys, Home, End Messages are captured by IE. How this can be avoided? How I Edit smoothly?

I've created an ATL service which offers an interface. In a test program i successfuly get a pointer to the interface but i can't see the service among the listed ones in the "Services" application.
Do you know how could i bring the service in the list as i can manually start and stop it? What exactly means the post-build registering step?
rechi

|
|
|

You need to register the service.
<servicename> -service
By default ATL registers it as a local server using servicename /RegServer
|
|
|
|
|
Thanx!
One more question: i saw in ServiceMain this call: LogEvent(_T("Service stopped")); . Is it about a loggin' system? If true, where is the log file?

You can see these events in the Event Viewer under Administrative Tools on Window NT systems.

Hi all, I'm using DirectX and am trying to see whether my graphics card can use the IID_IDirect3DTnLHalDevice ref before committing my application to it (where a nasty fail would happen if it couldn't). I have used the EnumDevices Callback function to obtain a D3DEVICEDESC7 pointer containing information about my Graphics card and am trying to check the dwDevCaps variable for the D3DDEVCAPS_HWTRANSFORMANDLIGHT cap by using:
if (!(lpdEnumDevice->dwDevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT))
return Error;
lpdEnumDevice is the correct structure, but this test always returns false! I have tried using the IID_IDirect3DTnLHalDevice id at CreateDevice time and it works! so I know it must support it. What am I doing wrong? I have a nVidia GeForce 2 Ultra (Gainward spec) graphics card.
Oh and thanks for the response Mike but the D3DDEVCAPS_HWTRANSFORMANDLIGHT was introduced in version 7 of the DirectX SDK (according to Microsofts instructions), it has a DWORD value of 65536 whilst my dwDevCaps member variable has a value of 1361, which is obviously why it is returning false. But why is this value so low? Do I hav to call a GetCaps() function or something? or re-inialise the D3DEVICEDESC7 structure in the callback function somehow? The Microsoft SDK articles seem to suggest I'm doing it the right way (don't they???), but it still fails to succeed.
How do I even know if its trying to access my nVidia card?
Ta all,
Alan.
