If you want only MSVC6 to search for your directory then:

tools -> options -> directories -> "show directories for" -> executable files

Remember this will only work when running your app inside MSVC. I you want to find the directory any other way, you will have to tell windows wher to search by adding the path of your directory into system path $PATH.

Actually, I want windows to search it anywhere.. So how do I add the path of my directory where all dlls are kept into $PATH?

Let say dlls are in C:\My Directory\Dlls

Actually in my case Dlls are on a network path.

Hi,

As iam a beginer in database application using VC++, i couldn't overcome
an issue. " Help me out"

Iam connecting SQL database through "ODBC" connectivity, everything works
out at normal operation.

if the SQL engine is stopped, and if i try to connect, the SQL API throughs
the Message Box--promting some connection failure.

How to disable the Message Box?????

It is not a "messageBox", it's called "Assertion".
First set break-points in your program and run it debug mode. at one point you will find your code screwing up. copy the block of code and paste here and start your quesion afresh. and dont post a blunt message like this.

Build your Application in RELEASEmode.
Warning:First understand the use of DEBUG mode. when an Assertion is thrown it says something has gone false.(wrong! ), so while developing always use DEBUG mode , so that it gives you warning about failed conditions. In your case, you said that when the server is down it throws an assertion. instread of just ignoring the assertion and moving to release mode, you implement try-catch() in your code. I mean to say "Exception handling". never ignore an assertion and bybass it.

Only after handling all the exceptions its advisable to move to release version,

good luck.

Problem with CEdit

Hi all

I get the Configuration for my application from the Registry. If i write the hostname-field(CEdit) into the Registry, only a few chars were be saved in the Registry. If i read the Registry-entry(eg. hostname), only the first letter were be printed. Do someone have an idea, what the problem is or better what i can do?
I'm really stumped...

and sorry for my english!

hopefull

Sounds like you're reading UNICODE data but interpreting it as an ANSI string.

Before I set the CEdit field with the value, I put the value in a CString. Isn't CString an UNICODE string?

Yeah, a CString "knows" whether to be UNICODE or ANSI. Can you show the reading a writing code?

I can't see what (if anything) you're doing wrong. I suspect the problem might be in the CRegistry class.

Hi there,

*Unicode file* means? An app that is aware of unicode? For that, you need to add the following to your stdafx.h

#define _UNICODE
#define UNICODE

Create the file with ::CreateFile, write the unicode text to the file with ::WriteFile and close it up with ::CloseHandle. Exactly the same as with ANSI characters, with the exception of wider characters, so that if you have

std::wstring text(L"Unicode text");

then write the data stream

text.data()

which has the byte size

text.size() * sizeof(wchar_t)

Was that what you meant?

Of course, there are abstractions that makes it easier to work with the Win32 file APIs. But grok the above and be a happier man. Roll eyes | :rolleyes:

How to access the child windows in MDI application?

Hi all,

I have an MDI application with multiple views (CScrollView, CFormView). Lets say there are five views opened (CScrollView -3, CFormView -2). There is a member "Child_Id" in the CScrollView class.

At one point of time - in the application class, I'd like to update (repaint) a CScrollView object with a given "Child_Id".

Give your hands please...

Thanks in advance,
Sarvan AL

You can take a look at the following functions...

CDocument::GetFirstViewPosition();
CDocument::GetNextView();
CMultiDocTemplate::GetFirstDocPosition();
CMultiDocTemplate::GetNextDoc();

CString Mid()

I have a CString object loaded with a string like "This is the first section$This is the second section$This is the end" so each section separated by '$'. I try to load the second section as csAnsprech = csComboBoxText.Mid( csComboBoxText.Find( '$') +1, csComboBoxText.ReverseFind( '$')); but this retrieves the second and third section, nut just the second one. What´s wrong here ?

Hello RadioOpa,

try this:

<br />
int i =0;<br />
while(i < csComboBoxText.GetLength())<br />
{<br />
	if(csComboBoxText.GetAt(i) == '$') // if we found the first separator in the string<br />
	{<br />
	i++; // move one place to skip the separator<br />
	while(csComboBoxText.GetAt(i) != '$') // now copy all characters in your string, while not found the next separator<br />
	{<br />
		csAnsprech += csComboBoxText.GetAt(i);<br />
		i++; // move to the next character<br />
	}<br />
	}<br />
	i++;// move to the next character<br />
}<br />

i hope that helps you!
regards

P.S. that sample from nave ist very good, i want just to show you another way without Find-Functions to extract a part of string

Many thanks, both ways solving the problem are excellent.

I changed code as follows:

iFirstSection = csComboBoxText.Find( '$'); // Find first '$'
iSecondSection = csComboBoxText.Find( '$', iFirstSection +1); // Find second '$'

csFirma = csComboBoxText.Mid( 0, iFirstSection); // Get first string section
csFirma.TrimRight( ' ');
csOrt = csComboBoxText.Mid( iFirstSection +1, iSecondSection - iFirstSection); // Get second
csOrt.TrimRight( ' ');
csFirmaID = csComboBoxText.Mid( iSecondSection +1); // Get last section
