Hello all,
I am new to Windows programming and VStudio.Net.
I am just trying to assess COM1 by writing a simple win32 console project using VS.Net. I built an empty console project and add the files from the MSDN MTTTY example.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp
but I have the following error while compiling:
Linking...
Init.obj : error LNK2019: unresolved external symbol __imp__InitCommonControls@0 referenced in function _GlobalInitialize
Transfer.obj : error LNK2019: unresolved external symbol __imp__timeSetEvent@20 referenced in function _TransferRepeatCreate
Transfer.obj : error LNK2019: unresolved external symbol __imp__timeKillEvent@4 referenced in function _TransferRepeatDestroy
LIBCD.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function _mainCRTStartup
Debug/Serial_win32.exe : fatal error LNK1120: 4 unresolved externals
Did I miss anything here? How can I get these 4 error fixed?
Besides, I just want to assess the COM ports using DOS style programs and not GUIs, should I must learn win32 API programming?
Thanks very much!

i don't think it is possible. Better u create a new Dll workspace and copy paste the function or class u want to export.

What kind of window?
Take a look at BitBlt(...)

its easy to show a bitmap on the widnow.
just place a picture control.
create a member variable for that control.
Load the bitmap using the API LoadImage()
Pass the handle obtained from the LoadImage fuction to the SetBitmap() function of the picture control

This way is not very good but it's a draw image
for draw image use WM_PAINT
Like this
CBitmap m_Bmp;
CBrush *m_brush;
m_Bmp.LoadBitmap('FileName');
//for other formats graphic use OleLoadPicture or cimage
m_brush=new CBrush(&m_Bmp);
m_Bmp.Detach();
HBRUSH CMyCpp::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
//if((pWnd->==this)
hbr = (HBRUSH)m_brush->m_hObject;
return hbr;
}
WM_PAINT is good for draw I suggestion WM_PAINT
OnPaint
First
/*
m_dcSource.CreateCompatibleDC(GetDC());
Bmp.CreateCompatibleBitmap(GetDC(),x,y);
m_dcSource.SelectObject(&Bmp);
then Load bmp file
and ....
*/
CPaint dc(this)
dc.BitBlt(0,0,800,600,m_dcSource,0,0,SRCCOPY)
or
dc.StretchBlt()
dc is destination for draw And m_dcSource is source

my project title is walking robot vision ...
the purpose of this project is to detect obstacle( develop software). we assume that the obstacle are not moving like chair, table and box. only the web cam that move.
so now i'm looking for any source code that can detect non moving obstacle (camera moving). I've tried run source code that i got, but it not work ...
thanks ...

since the camera is moving u r unable to identify that wheater it is a camera
movement / object movement.
Right !!
Grab 3 t 5 image in specific intervel of time, see to that the u need to set the time intervel so that , u will not have any motion in the camera with in this interval(THE CAMERA SHOULD BE MOTION LESS WITH WITH THIS INTERVEL ), and u apply some pattern reco./ and also check the size to the stable object,
(but u need to thing over for the very very slow motion obstacles)
ok any how try it , first , it will not be a major problem
Hope u got the LOGIG
and also to forget to inform how far u sucecceded
ALL THE BEST

what we can do with NAT API?

What do you want to do? Only the Server OS's have a NAT service (Windows 98 and later have Internet Connection Sharing, which has a very primitive NAT implementation), and I don't think it can be configured by other applications.
If you're talking about client-side NAT (using a NAT-enabled firewall), there's no reason to do so - it's completely transparent to your computer.

The Network Address Translation (NAT) Traversal API provides applications with the ability to configure port mappings on a remote Internet Gateway Device (IGD) that uses NAT. The IGD could be a personal computer running Windows XP with Internet Connection Sharing and Internet Connection Firewall (ICS/ICF) enabled, a personal computer running software that provides NAT, or it could be a dedicated hardware device.
I got these information from MSDN 2003.

while interfacing oscilloscope with pc,can i plot real time display of oscilloscope in pc using vc++?
where do i refer?
please do reply..
with warm regards

It depends of what you mean exactly by 'real time' ? What is the accuracy needed ?
|
|
|
|
|
what i am doing actually is z-scan experimetnt to analyze a sample.each sample ll give a unique signature..while doing the experiment,a window should be opened so that the user can input the necessary data.. and with the data energy versus position graph should be plotted..
now it is being done using xmgrace in linux..
my project is to switch it to windows..so i have to find a graph plot software in windows.. can i do it in visual basic or something like that? other interfacing part is written in c.. so i have to call the graph plot part from c..
with warm regards

You can do it in C++ but you'll have to use a win32 app at least (MFC is better because it will be easier). Do you have any experience with the MFC ?
If you want, there are some plot controls on this website. I developped also a chart control that can be used for real-time data (what I did, was to plot a point approx every 30 msec). This was working fine on a PDA so it will work even better on a computer.
If you are interested, I can find the sources and send them to you (I have to search a little for that). But unfortunately there is no real documentation with it.

i have no previous experiance with MFC..
it would be very helpful,if u can send it.
thanks

hi! everybody,
I use AnimateWindow to do some special effects and it works well.
But when I put some controls(like edit label button...) on it,then the window shows nothing.
I try to find something solutions out...,
MSDN wants me to take care WM_PRINT or WM_PRINTCLIENT messages, if I use AnimateWindow.
I have no idea how to draw the controls on WM_PRINTCLIENT by myself.
by the way I use DrawText in WM_PRINTCLIENT it is ok.
Any one can help me?! thank you very much.

Send the controls a WM_PRINT message to get them to print themselves.

someone tell me it from crt0.c any way, is it global variable?
I think it must a global variable. because it be used in my app without passed . forexample
void myfunc()
{
string c = __targv[0]; //__targv is not be pass to the function.
//but it can be use ,so it must a global
}
|
|

If 2 same global variable exist in seperate dll or lib.
must a conflict happen?
|
|
|
|
|
For libs you may have a conflict.
Not for a DLL.

Hello,
Why do you have the same variable in 2 locations? Do they share the same purpose? If not, do they share the same namespace? If the answer to the last question is 'yes', you have a problem. This problem will only surface if you use the headers of both the DLL and the static library. You'll get name collissions. To solve this problem, you need to put the variables in different namespaces or give them other names.
Hope this helps.
