If you are using MFC then try,

BeginWaitCursor();
...
EndWaitCursor();

or

CCmdTarget::BeginWaitCursor();
...
CCmdTarget::EndWaitCursor();

Thanks.

u can use SetCursor function

SetCursor(LoadCursor(NULL, IDC_WAIT));

IDC_WAIT is HourGlass

In addition to your other replies, you might be up/downloading the file using some sort of background thread. If the upload takes any length of time, I *hope* you're using a thread to keep your UI responsive.

In which case, you will also have to handle WM_SETCURSOR, other wise as soon as the mouse moves, your cursor will go back to normal.

Hi all,

I have used this csp when I initiate my decryption:

CryptAcquireContext(&hProv,NULL,MS_ENHANCED_PROV,PROV_RSA_FULL,0);

I have also checked http://msdn.microsoft.com/en-us/library/aa386986(VS.85).aspx[^] and have verified that 3des is supported. Is it possible that http://www.codeproject.com/KB/web-security/Cryptography_MD5_TriDES.aspx?display=Print[^] may have a different output from a c++ version of the code? Can anyone give me a c# encryption and an equal c++ decryption examples?

Thanks,
Jayjay

any implementation of 3DES must give the same results as any other implementation, given the same inputs.

You have at least 3 possibilities:
1. as someone already mentioned, use the auto-buddy feature (set that to true in the dialog editor for your spin button and make sure the spin comes right after the edit in tab order)
2. specify a control variable too for your edit button (CEdit) and pass that to SetBuddy
3. use GetDlgItem() to get a pointer for your edit control and feed that to the SetBuddy call (presuming you already have a CSPinButtonCtrl type member assigned to your spin control.

i have used GetDlgItem(ID name) and then what i have to pass in the SetBuddy function.

Sorry, i got mixed up there, i thought you had the double for your spin button, not your edit, i will edit my previous post and then check it again.

Ok No problem,

i have created control variable for spin control already.

m_voltspin.SetRange(0,50);

i have memeber variable for edit box in that i have declared as double.

i have set true in the spin control properties
(Auto Buddy), problem is am not able to see the values in the dit box when i press up / down the spin control, it is updating somewhre.

There's a spin button style called "Set buddy int" (UDS_SETBUDDYINT), make sure that is set for your spin button.

do u have any idea

Actually i have Rich text contol present in my dialog. I will get messages from the board, when the messages exceeds the size of the window, scroll bar automatically comes because of i had set the scroll bar(Vertical scroll bar) property of Rich Text Control.

My question is, when message exceeds the window size, the scroll bar automatically goes up. i don want scroll bar to move up rather it should go down, then only i can able to see latest updates form the board at time itself.

Thanks in advance,

Thanks,

Balaji

Probably you have "Auto buddy" property set and your TAB order is not properly set.

As some one has already suggested you can set buddy window using SetBuddy member function of CSpinButtonCtrl class.
I hope it helps.

In the resource editor:

set the spin control's tab order immediately after the edit control

set the spin control's alignment property to Right (or Left)

check both the "Auto buddy" and "Set buddy integer" checkboxes

In the dialog's OnInitDialog() method, set the value via the edit control's SetWindowText() method.
