Since the USB device I'm writing to has a low battery, there is never a return message packet sent back to Windows from the WriteFile. So, the system just hangs in the WriteFile event forever. I put a breakpoint on the line after the WriteFile and it never gets there. Is there any way to cancel the IO after say 5 seconds of inactivity?

Interesting. In terms of C++, one solution is be an exception try/catch.

I have a CFormView and I need to capture the ESC key. The control the has the focus always receive the OnChar but the form never does. I don't want to use an Accelerator nor any code on the controls.
Any Ideas?

Just a guess:
Override PreTranslateMessage in your CFormView.

PreTranslateMessage is never called on the CFormView
|
|
|

thats how i did it.. here is some code from one of my dialogs that is derived from CFormView..
in my .h
BOOL PreTranslateMessage(MSG* pMsg);
in my .cpp
BOOL CST3WKSHT::PreTranslateMessage(MSG* pMsg)
{
CSCTaxApp* pApp = (CSCTaxApp*)AfxGetApp();
if(pMsg->message==WM_KEYDOWN && pApp->m_bEnterAsTab)
{
if(pMsg->wParam==VK_RETURN)
pMsg->wParam=VK_TAB;
}
return CFormView::PreTranslateMessage(pMsg);
}this converts my keypresses from enters to tabs.. and it does work.. hope that helps
still a newb.. cut me some slack :P

Hello,
After using VS6 a lot I found out how to save my work environment (window positions, toolbar and menu bar content and positions, fonts, colors etc.) by experimenting with the registry. This is extremely useful when you reinstall your machine or if you use a lot of test machines where you just don't want to reconfigure everything.
While migrating to VS7 I find that this is no longer possible. I just don't know where my settings are stored. I tried saving all the registry settings I could find (and this is bad, because I only would like to save the parts that are related to the UI - and is of no help anyway), the files I thought that are worth saving but I am still unable to backup my environment.
Anyone knows where all this stuff gets saved? 
Regards,
Levente

Unfortunately, not me. But I have often wondered about this myself.
From what I have heard the config is stored all over the show, registry, config files, etc.
If any one figures this out. Please share. ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

It seems we're not alone... How do I move my VS.NET Studio Settings to another Computer?[^]
Oh and this message probably should be in the VS.NET IDE Issues forum.

Yeah, right. I just saw that there is such a forum called "VS.NET IDE issues".

How do you make a toolbar or dialogbar in a DLL that you can dock with the main window in mfc, and if possible have the DLL handle the messages output from the toolbar.
Is there any easy way to do this?

I used Seagate Crystal Report 8.5 with my VC project. It's excelent on printing and preview. But when I export the datasheet to MsWord or MsExcel, the column's borders and the row's borders disappear (but when I export to Acrobat PDF, it works)
Just a question: why Seagate can't export completely with border on MsWord and MsExcel ?

Hi,
I am looking for books that will help me learn about windows networking API's. Say I want to know the ways by which I can transfer a file from one computer to another under windows 2k. Obviously FTP is the answer, but are there any other ways ?
I am looking forward to your suggestions.

if you are just copying a file and its a local network then you can use regular file copy commands and just pass the network name of the computer and path.. like '\\mycomp\uploads\'.. it really depends on the use as to what methods you would want to use.. obviously you wouldn't want to use ftp unless you are going to have machines running ftp servers as well..

But why buy expensive books when u learn learn learn from the internet! 
It's how i got all my knowledge (not that its that much lol) and the books i did buy (3 now, and only 1 is about C/C++) didn't help me much at all!
Oh wait.. there's a simple answer to my first question. Don't say it! To pay the authors salary because we might end up writing a book of our own one day and we would want people to buy it and not just look it all up on the internet.

Hi,
How can I access to I/O port in NT Windows?
Thank you for your guides, beforehand.
|
|
|
|
|
You can use WinRT http://www.pds-site.com/Bsquare/WinRT/default.htm[^].
Or you could write your own device driver.
However, user mode code isn't allowed to access i/o ports directly since that would be a security violation.

i am so utterly frustrated right now.. i have been trying to pass a string from VB into a function, modify it and return it back to VB.. but i just cannot understand this BSTR crap.. i have tried to accomplish this 2 ways and im stuck both.. so im gunna list em both, and maybe someone will know how to fix one? thanks a bunch for any advice..
Problem number 1:
I pass 3 variables into my function..
FindBankName(strFilename, strRoutingNumber, strBankName)
when i call this function from VB i pass it these values in this order:
("C:\\FedACHdir.txt", "282976020", "bankname")
but as you will see below my c++ function does not get them in this order..
c++ function:
void __stdcall CFpsPayTaxxApp::FindBankName(BSTR strFilename, BSTR strRoutingNumber, BSTR strBankName)
{
CString strTemp;
strTemp = "The Filename passed is: >" + (CString) (LPCTSTR)strFilename + "<";
AfxMessageBox(strTemp);
strTemp = "The RoutingNumber passed is: >" + (CString)(LPCTSTR)strRoutingNumber + "<";
AfxMessageBox(strTemp);
strTemp = "The BankName passed is: >" + (CString)(LPCTSTR)strBankName + "<";
AfxMessageBox(strTemp);
}
what i get for output is 3 message boxes.. the first says ">282976020<", the second ">bankname<", and the third has funky characters.. so the first parameter is never seen.. i have tried passing by reference, not by reference, passing with a return value, without a return value, passing as char* instead of BSTR, but i never get the first parameter.. the other problem with this approach is that i crash when i modify the passed in BSTR's..
Problem number 2:
I tried to take an ATL dll that is on CP which has examples involving BSTR's.. i got that dll to work fine with the parameters being passed.. the function even modified the string and returned it as modified (which i cant seem to do in the first method at all without crashing).. the problem here is that i can't seem to modify the string and return it.. probably because i am not handling the BSTR's properly.. but at least the example works, its just way to cryptic for me.. here is what i have trying to just return the variable modified.. it doesn't work either..
void __stdcall GetBankName(BSTR strFilename, BSTR strRoutingNumber, BSTR strBankName, BSTR strErrResponce)
{
strBankName = "what the?";
}this doesnt change the text.. and the example i have i cant even follow..http://www.codeproject.com/dll/superdll.asp[^]
Conclusion:
problem #1 working would be alot better for me because i could use CStrings and other MFC things, where as problem #2 uses ATL and I am so lost dealing with these BSTR strings.. all I need to do is be able to set a char* array to a BSTR.. but i just cant seem to follow it..
if you have any idea what im doing wrong in #1, or can offer some suggestions on understanding modifying BSTR's in problem #2 i would be very appreciative.. thanks

"(CString) (LPCTSTR)strFilename " is very bad idea.
try
a)
#include "comdef.h"
CString str = _bstr_t(strFilename);
b.)
CString str = OLE2T(strFilename);

ill keep that in mind.. how would i turn it back to a CString, or better yet how would i turn a BSTR to a char* and then back to a BSTR?

void functionF(BSTR bstr)
{
CComBSTR cBstr = bstr;
CString str(bstr);
CString strAppend;
strAppent = str + CString(bstr); //Appending Strings
strAppend += str;
//Similiar with CComBSTR and _bstr_t
}

hrm.. seems the whole problem is that i was listing the classname in front of the function like:
void __stdcall CFpsPayTaxxApp::FindBankName(BSTR strFilename, BSTR strRoutingNumber, BSTR strBankName)
i took off the classname in front of the function and it now the vars come in fine..
void __stdcall FindBankName(LPSTR strFilename, LPSTR strRoutingNumber, LPSTR strBankName)
wierd stuff.

Hello,
I have never tried to load a dialog box from a dll.. I have created a Static MFC DLL and created a dialog within the dll.. I used this to export the class hoping that this would allow me to use the dialog..
class AFX_EXT_CLASS CSettingsDlg : public CDialog
{
public:
CSettingsDlg();
~CSettingsDlg();
enum { IDD = IDD_SETTINGS }; <------HERE
..... BLAH BLAH
The problem is when I add the .lib, .h and dll to the other application and try to compile it I get an error on this line..
enum { IDD = IDD_SETTINGS }; <--
Any ideas?
