How can I convert an _int64 variable to double?
|
|
|
|
|
How about:
__int64 i64;
double d = (__int64) i64; If you are using the .NET framework, check out the Convert.ToDouble() method.
Another way would be like:
__int64 i64;
char s[32];
sprintf(s, "%I64d", i64);
double d = atof(s); I've not explicitly tried either of these.

How can I turn off all network traffic and then later turn it on again.

A fixed font should allow 80 columns across a screen. However this doesn't quite fit when there are standard borders around the window when viewed in maximized mode.
Can anyone suggest how I can display a window, based on CScrollView, which does not have the normal side borders. Either no border or a very narrow border.
All suggestions appreciated.

Does ShowWindow(..., SW_HIDE) not do what you want?

I use ShowWindow(..., SW_HIDE).
It will be hidden. But It will be shown in Task List.
I don't know the way to hide it in Task List.
|
|
|
|
|
I do not know of a way to hide processes (those items on the Processes tab) shown by Task Manager. Why do you need this functionality?

"Run in background" is a phrase not used with Windows since it is a multitasking OS.

This sounds very suspicious. Can you explain why this should not be considered a virus, worm, or trojan horse?

Have you seen EasyCafe, an application to manage PC room ? I want to write an application same it.
When I use Ctrl+Alt+Del to show Task Manager, I don't see it in Task Manager. So I cannot kill it.
|

As I understand it, to trap the Ctrl+Alt+Del keystroke combination requires the creation of a custom GINA DLL.
For Windows 9x and Windows Me, you can use SystemParametersInfo() to trick the system into thinking that a screen saver is running.

The solution trapping Ctrl+Alt+Del (using SystemParametersInfo) is not appropriate for my application. Because it will also trap Alt+Tab.
My application allows users :
- kill other applications (using Ctrl+Alt+Del)
- switch among applications (using Alt+Tab).
I'm finding the way to solve this.

I have just known the way to hide an app on Win 9x/Me :
Call RegisterServiceProcess of kernel32.dll
|
|
|
|
|
That function registers or unregisters a service process. I'm not sure how that compares to hiding an app on Win 9x/Me.

I've just written a program in WinMe. And I saw that it works well :
My program is not shown in Task List.

Perhaps you should write an article on your findings so that everyone can benefit.

OK. I will write an article about my findings.

Whats wrong with my code:
Control ^editText = gcnew frmChangeTxt::txtChangeText();<br />
this->lblText->Text = editText->Text;
I'm using it to try and access the text in text box 'txtChangText' from form 'frmChangeText' and make the label in the main form 'frmMain' that text from the textbox. I'm doing this from a button control in the mainform by the way.
If doing it this way isn't possible, can someone tell me the right way?
Thanks in advanced.

This doesn't look like VC++ code. Am I missing something?

Hi All,
Seasons Greetings!!
Im Mirza Faizan, currently a trainee at ELECTRONICS AND RADAR DEVELOPMENT ESTABLISHMENT, DRDO, Bangalore. In my academic project, I have to develop a Device driver Hardware Acceptance Test for a communication card for Control and Display Unit of a RADAR. I have seen your project on www.codeproject.com, and immediatelt realized that you can be my help!! plz plz plz...
My problem is that I am developing GUI for the driver in VC++. And I am having trouble with the following thing:
1) I have to develop a GUI in which POST is done for 24V, 5V, 3.3V, 2.5V.
*If the check is successful, then the button should become GREEN and the caption on the button should be 'OK'.
*If the check is failed, then the button should become RED and the caption on the button should be 'FAILED'. And when the user click on button, a dialog box should appear telling him what to do next.
2) Please also do tell me how to declare variable (not attached with the controls, but extra variable where I should store values of voltages which are checked.
3) Please tell me how to add C,C++ code in the GUI developed in VC++. I mean, Im developing GUI in VC++ and writing device driver in C, C++
Please help me with this. I'll be highly obliged with this kind act of yours.

You are working as a Trainee means you are supposed to be given training and guidance on what to be done.I myself feel sad and shame to see someone representing DRDO crying of not knowing how to start
a RADAR supporting software, which has life of many soldires in its(software's) hands.
This is why DRDO of India is called White Elephants. If my knowledge is right Electronics and Radar Development Establishment comes under DRDO.
Don't think I am bashing on you because you have doubt on VC++ but its on the authorities who doesn't seems to assist the trainees like you.
There is no spoon.

You are right Mr. Suhredayan, but still your comments hasn't solved the problem. It would be much better if we stop criticizing the system and start action!! How easy is it to criticize?? Just some lines of mails....!!! Dont forget its DRDO which has developed missiles like AGNI, TRISHUL, AKASH, PRITHVI and so on... Its DRDO which is developing Avionics and Electronics Counter Measures (ECM) for Fighter Aircrafts. When will we Indians start thinking like developed countries like Americans who say "ASK NOT WHAT YOUR COUNTRY CAN DO FOR YOU, ASK WHAT YOU CAN DO FOR YOUR COUNTRY" By giving plain criticism and NO answer to problem, even YOU stand among those WHO ARE JUST GOOD AT CRITICIZING!!!
