hi,
Obviously u know the caption of your application..[I mean caption on the tittle bar of parent window]
use FindWindow API to search with that window caption...if FindWindow API succeeds u will get the handle for that..
then u send the window resize message with that handle otherwise go as normal...
try this in InitInstance...
With Regards

Hi all
Am familiar with serial port communication in VC++.
I have written a software for connecting a datalogger device into the serial port and reading the data from the device.
Now I want to make this device and software able to be connected to the USB port, since most the laptops have only USB.
Please help me regarding how I can start sending and recieving data via the USB port in windows.

If using a standard USB to serial convertor your code "should" work just fine using the COMx port installed by the driver (usually COM3 or higher), however the USB serial ports so not act quite the same as UART based serial ports, in particular they tend to appear "blockier" (data arrives in distinct blocks rather than in a more continual stream).
I have found that this can interfere with the expected action, particularly the timing of serial messages.
If you want to add the USB port to the actual datalogger hardware I suggest you look at something like the CP2102 (Silicon Laboratories). This is a very small IC that can easily be added to your product and converts from serial to USB (no crystal required which keeps the cost down).

Extreme caution is preserved when using those port converters. I've used some and all of them mananged to blue screen WindowsXP! I've never seen one of those since Windows 98.
The problem with those USB serial ports is that most of the drives implement CancelIO wrong and that causes a lot of trouble. More information about this can be found in the CSerial[^] article.

Describe, in detail, what the problem is. Simply saying that it is broken is not very helpful.

When I clic on the print button on the printpreview screen there is this message : this program will be stopped because it does an operation not permit. If this error continue, let contact your reseller.

So what does the code look like that runs when the Print button is clicked?

Hi all,
Now I have a list controls; the list is set in Icon mode and I use it to display thumnail image (look like explorer in winxp to show images in thumbnail mode).
When I put scroll (Vertical) position at the min position (zero value); items rectange (GetItemRect(0,&rect, LVIS_BOUNDS)) at the first line always is zero value! How can I change this value? (mean I can make a distance between item and the ceil of list control rect);
Similarily with items at the last line when I put scroll position at the maximum value: bottom value of these items always dash the floor of list controls rect! Can I change this distance?
In otherwise, if list control is a box; I see items always are fixed in the box; How can I enlarger this box???
Please tell me some ideas!
Thanks!

I dont think you can change the layout algorithm of the list control.

now when i run it without the ListALL fuction it works but when i run it with the ListALL fuction i get syntax errors can anyone see what im doing wrong.

you'll need to edit your post to make sure all the <'s and >'s show up. as it is now, we can't tell how you've declared the vectors.

I have created a SDI application (with no Document/View) support. I 'm trying to attach a CBitmap button, but dose not displayed at all.
Here is my code (that handles the WM_CREATE message on the CChildView class):
<br />
int CChildView::OnCreate(LPCREATESTRUCT lpCreateStruct)<br />
{<br />
if (CWnd::OnCreate(lpCreateStruct) == -1)<br />
return -1;<br />
<br />
RECT rect;<br />
rect.left = 20;<br />
rect.right = rect.left + 20;<br />
rect.top = 100;<br />
rect.bottom = rect.top + 20;<br />
<br />
CBitmapButton bnPlay;<br />
if(bnPlay.Create(NULL, WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, <br />
CRect(&rect), this, IDC_BN_PLAY)==0)<br />
{<br />
AfxMessageBox("BnPlay cannot be created", MB_ICONSTOP);<br />
return -1;<br />
}<br />
<br />
bnPlay.LoadBitmaps(IDB_BNPLAY);<br />
bnPlay.SizeToContent();<br />
return 0;<br />
}<br />
The result of this code is an empty window...

I have created a CBitmapButton in the main window of an SDI application, but I can't figure out how to implement the button. I would like to use it to open a dialog. Here is the code I used to create the button. Thanks for any help you can give.
RECT rc;
rc.top=10;
rc.left=10;
rc.right=95;
rc.bottom=95;
CBitmapButton *Winbut = new CBitmapButton;
Winbut->Create(NULL,WS_CHILD|WS_VISIBLE|BS_OWNERDRAW,rc,this,IDB_SITBUT);
Winbut->LoadBitmaps("SITEIMAGEU","SITEIMAGED","SITEIMAGEU","SITEIMAGEX");
Winbut->SizeToContent();

The last parameter of the create function is the ID of the control you are creating. It is an integer.
Let it be 200.
Then declare a function in the header for the class.
afx_msg void OnButtonWhatever();
In the message map in the .cpp file:
...<br />
...<br />
ON_COMMAND(200,OnButtonWhatever)<br />
END_MESSAGE_MAP()
Then implement the function:
void [Your Class Name Here]::OnButtonWhatever()<br />
{<br />
MessageBox("The button was clicked. He He!");<br />
}
this is this.

hi all,
i am trying to export a class template from a static library using __declspec(dllexport). The library will compile fine, however importing it into my second project and attempting to instantiate it produces a number of unresolved external symbol linker errors, for each method. Is it possible to export templates from a static library?
|
|
|
|

you need to provide the entire definition of the template, in order to 'export' it. a template is not a class - it's just a recipe that the compiler uses to make a real class. any compiler using your lib will need the whole template definition to build that class.
this[^] might help.

thanks for the link. so, there is no way to export the actual template, so that clients can recreate the templates with any types they need? What i am basically looking for is a way to reuse class templates in multiple projects. any suggestions?
