The signal strength values comes from a receiver, very much like a radio which will be connected to our serial port. I am not sure the method you were referring( maybe you can further elaborate in a simple way which i can easily understand?). What I did was my program will be collect signal strength values at the predefined frequency. As the signal strength value of a fixed frequency keep on changes, I created a timer with 250ms time interval to read and update the display. This timer will trigger an event to collect signal strength and update the meter -- modified at 11:05 Tuesday 6th February, 2007

Hello , I am new to VC++ 6.0 I am now developing a MFC dialog based project which will display the signal information in real time and signal strength. [IMG]http://i176.photobucket.com/albums/w196/well\_aisec/image-1.jpg\[/IMG\] I need to have 1 analog meter which will constantly update the signal strength value as well as an oscilloscope which will graph the received signal in real time. What I will do to set a Timer which will trigger every 250ms for update and display in Analog meter. At the same time I need to perform real time graphing for the signal. Meaning the two task is perform asynchronously. Now here's come the problem. As the timer is triggered in fast speed, my program seems very laggy to perform both operation in parallel. May I know what's the problem and solutions?The timer consume a lot of memory space and processing speed? How to improve the program so that it can progress smoothly. Thanks

I afraid the article's writer will not read my question...that's why I choose to post here. I will appreciate any help from you.

Pls refer to here- http://www.codeproject.com/staticctrl/LEDScreen.asp How To Use Using the class is very simple. 1. Create project. 2. Link library msimg32.lib to project. 3. Add LEDScreen source files to project. 4. Place on a dialog any bitmap image (picture static). This is optional. 5. Place on a dialog (owner bitmap if exists) CStatic. With ClassWizard, create variable m_screen for this CStatic. 6. In your dialog declaration, rename CStatic m_screen to CLEDScreen m_screen. Like this: I am a Visual C++ 6.0 beginner user. I don't understand what is the 2th step:Link library msimg32.lib to project. How to do exactly to link the library??

I am using visual c++ 6.0. I wish to use the COleVariant::GetByteArrayFromVariantArray member function but the compiler generates error message : GetByteArrayFromVariantArray is not a member function of COleVariant. Why could this happen?? Is this function available only in VC++ 2005?? Is there any way to retrieve a byte array from variant array?? Thanks. I will appreciate any help from you.

Hello. I am new to Visual C++. I am doing a computer control software to control a receiver and i need to capture the signal and plot it out. May I know which MFC class library is suitable to do graph plotting?? As far as i know there are MsChart control and CGraph class libray...what are the differences in these two?? Are both applicable in Visual C++?? I tried to find the download source for both of these class libray ..Is there any download link for all the MFC class library?? thanks in advance.
