RegSaveKeyEx and RegRestoreKey, I think.

ppl tell me RegRestoreKey is not available on win9X

Those people are correct. On Windows 9x, the registry consists of the system.dat and user.dat files, which are located in the Windows folder. Read MSDN article Q132332 for more.

Hi All,
I am working with a custom titlebar. I want to get the current size of the close button and set the value for the button which i am drawing. The problem is, if i put the left point in a CRect as
pCapRect->left = rcWindow.Width()-(sizeButton.cx);
and draw the close button using
pDc->DrawFrameControl(pCapRect, DFC_CAPTION, DFCS_CAPTIONCLOSE); // For Close
the left position (also the size) is not getting aligned with the default close button(which shows up), when i change from one skin to another.
Awaiting your reply

I need to print an enhanced metafile of size 26MB. It is containing a bitmap that is rotated while printing. The bitmap is 25MB in size.
If the emf is generated with bitmap rotation, the printer hangs while printing.
If the rotation is removed, the printing operation works fine.
Please help me if you find any solution to the printer hanging problem.
Thanks

Hi,
One of services is crashing randomly. The service is developed in VC++.
I got only the user dump file along with Dr. watson log. I am using windbg
tool to find out the location of the crash. Can anybody suggest me, how to
find out the exact location of the crash.
Thanks

This may not work on your existing program, but I found this article extremely useful and might be of interest to you for future releases.

Select New from the File menu. Click the Projects tab. Select MFC AppWizard (exe) from the list. Give the project a name. Click the OK button. There you will see the option for SDI, MDI, or dialog application.

HI,
I've to set values in combo of 1 dialog box.
Then i've to call that value in the function in another class.
The function is defined in another class.
Dialogbox//
void settings::OnOK()
{
CString strTemp;
UpdateData();
nreturn=((CComboBox*)GetDlgItem(baudrate))->SetCurSel(m_dcb.BaudRate);
n2return=((CComboBox*)GetDlgItem(paritybits))->SetCurSel(m_dcb.Parity);
n3return=((CComboBox*)GetDlgItem(stopbits))->SetCurSel(m_dcb.StopBits);
strTemp.Format("%d", m_dcb.ByteSize);
n1return=((CComboBox*)GetDlgItem(databits))->SelectString(0,strTemp);
UpdateData(FALSE);
CDialog::OnOK();
}
class// fn definition:
BOOL serial::ConfigurePort(int BaudRate, int ByteSize,int fParity, int Parity, int StopBits)
{
if((m_bportready=GetCommState(m_hcom,&m_dcb))==0)
{
MessageBox("GetCommState error","Error",MB_OK+MB_ICONERROR);
CloseHandle(m_hcom);
return false;
}
m_dcb.ByteSize=ByteSize;
m_dcb.Parity=Parity;
m_dcb.StopBits=StopBits;
m_dcb.fBinary=TRUE;
m_dcb.fDsrSensitivity=false;
m_dcb.fParity=fParity;
m_dcb.fOutX=false;
m_dcb.fInX=false;
m_dcb.fNull=false;
m_dcb.fAbortOnError=TRUE;
m_dcb.fOutxCtsFlow=FALSE;
m_dcb.fOutxDsrFlow=false;
m_dcb.fDtrControl=DTR_CONTROL_DISABLE;
m_dcb.fDsrSensitivity=false;
m_dcb.fRtsControl=RTS_CONTROL_DISABLE;
m_dcb.fOutxCtsFlow=false;
m_dcb.fOutxCtsFlow=false;
m_bportready = SetCommState(m_hcom,&m_dcb);
if(m_bportready ==0)
{
MessageBox("SetCommState Error","Error",MB_OK+MB_ICONERROR);
CloseHandle(m_hcom);
return false;
}
return true;
}
In main class// this fn is called as
void CComDlg::Onreceive()
{
//if(!(port.ConfigurePort(115200,8,0,NOPARITY,ONESTOPBIT)))
if(!(port.ConfigurePort(comb.nreturn,comb.n1return,0,comb.n2return,comb.n3return)))
// if(!(port.ConfigurePort(comb.m_baudrate,comb.m_databits,0,comb.m_paritybits,comb.m_stopbits)))
{
MessageBox("Cannot Configure Communication Port","Error",MB_OK+MB_ICONERROR);
port.ClosePort();
}
My Question is in void CComDlg::Onreceive() ,
while using first if condition, it executes well.
But while using 2nd or 3rd if condn,
It gives " Set Comm state Error" and "Cannot Configure COmmn Port".
What's the problem there?

Check whether the combo items are properly populated.
Get the CComboBox item of the parent by using GetParent() function, fill the combo by the value from the popup dialog say in ur case settings.

if(!(port.ConfigurePort(comb.nreturn,comb.n1return,0,comb.n2return,comb.n3return)))
At this point, what are the values of comb.nreturn, comb.n1return, comb.n2return, and comb.n3return? If they are not the same as those used by the call to ConfigurePort() that uses hard-coded values, it shouldn't surprise you that the results would be different.

Ok...I solved my previous questions.
This question deals with a deleteItem function that is to delete an item from an array. And I am passing a sorted array, its size, and the target element...this is what I have so far...
<br />
<br />
<br />
<br />
<br />
#include <iostream><br />
#include <string><br />
using namespace std;<br />
<br />
template<typename T><br />
void sortArray(T arr[], int size);<br />
<br />
template<typename T><br />
void searchArray(T arr[], int size, T target);<br />
<br />
template <typename T><br />
void deleteItem(T arr[], int &size, T target);<br />
<br />
template<typename T><br />
void printArray(T arr[], int size);<br />
<br />
int main()<br />
{<br />
<br />
int size;<br />
int target;<br />
int arr[10] = {9,8,7,6,5,1,2,3,0,4};<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
system ("pause");<br />
}<br />
<br />
template<typename T><br />
void sortArray(T arr[], int size)<br />
{<br />
int smallest;<br />
T temp;<br />
for(int i=0; i<size-1; i++)<br />
{<br />
smallest = i;<br />
<br />
for(int j =i+1; j<size; j++)<br />
{<br />
if(arr[j] < arr[j-1])<br />
smallest = j;<br />
}<br />
<br />
temp = arr[j];<br />
arr[j] = arr[j-1];<br />
arr[j-1] = temp;<br />
}<br />
<br />
}<br />
<br />
<br />
<br />
template<typename T><br />
void searchArray(T arr[], int size, T target)<br />
{ <br />
int size;<br />
int low = 0;<br />
int high = size -1;<br />
int mid = (low + high)/2;<br />
int target;<br />
<br />
bool found = flase;<br />
do<br />
{<br />
if(target == arr[mid])<br />
found = true;<br />
<br />
else if(target < arry[mid])<br />
high = mid-1;
<br />
else <br />
low = mid +1;<br />
<br />
if(!found)<br />
{<br />
mid = (low + high)/2;<br />
}<br />
<br />
}while (high >= low && !found)<br />
<br />
<br />
<br />
}<br />
<br />
<br />
template <typename T><br />
void deleteItem(T arr[], int &size, T target)
{<br />
<br />
<br />
<br />
}<br />
<br />
<br />
<br />
template<typename T><br />
void printArray(T arr[], int size)<br />
{<br />
for(int i=0; i<size; i++)<br />
{<br />
cout << arr[i] << " ";<br />
}<br />
}<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
Can anybody help me with the delete item method...I'M SO LOST!!!!! 
THANK YOU FOR YOUR TIME!

If we can view a 10-item array as:
+-+-+-+-+-+---+-+
|0|1|2|3|4|...|9|
+-+-+-+-+-+---+-+ then to delete the item at position 3, items 4-9 must be moved one position to the left. In other words, item 4 becomes item 3, item 5 becomes item 4, etc. Make sense? What to do with the empty spot that results from moving item 9 depends on how you want the array to behave. It can be removed, or it can be left intact so that the next addition does not have to allocate any new memory.

Well, Im better able to define the question.
How can I change the system-defined default printer?
I can change the default printer for a specific
application, but how can I change it for the system?
Please, any response any one can give me will be greatly
appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

Are you sure you want to do this? If a user has set their default to be printer A, and, after running your application, the default is changed to printer B, they aren't going to be too happy. Do you agree?

how do i uncheck a menu item after i check it with CheckMenuItem(). How do i find whether a menu item is checked or unchecked?
|
|
|
|
|
MSDN:
BOOL GetMenuItemInfo(
HMENU hMenu, // handle to menu
UINT uItem, // menu item
BOOL fByPosition, // meaning of uItem
LPMENUITEMINFO lpmii // menu item information
);
MENUITEMINFO structure contains a flags(fState) which will specify whether the item is checked/unchecked.

You can use this on Udate_Command_UI Handler, which will be called just b4 showing the toolbar items
