In your CListCtrl derived class, overload the MeasureItem handler. Note that we don't call the base class MeasureItem as this will change the item height back to the default.

<br />
void CCustomListCtrl::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)<br />
{<br />
    if (lpMeasureItemStruct->CtlType == ODT_LISTVIEW)<br />
    {<br />
         lpMeasureItemStruct->itemHeight = 20;<br />
    }<br />
//Don't call the base class MeasureItem as the base handler will change the itemHeight back to the default<br />
//Height!<br />
//	CListCtrl::MeasureItem(lpMeasureItemStruct);<br />
}<br />
<br />

I think you'll need to roll your own.

I need to register IITAPIEventNotification interface in order to proces events. For that I need a callnot.h and callnot.cpp files, but I don't have them. How can I get them?

Hi
Is it possible to show contacts interface and use it to fetch number and email address or we have to iterate through contacts ourselves and show information in own window and controls.

Hi
Well to be more explicit:
We have common dialogs for picking colors,fileopen,filesave etc.
Is there any similar option available for getting a phone number to dial from contacts stored on a user's Pocket PC

timers or appending

I should recieve an array of bytes of lenght 212 at a time from the sensor, but am recieving some bytes ie,set X[] at one time and some bytes i,e set Y[] of different lengths. how could i set the sensor for not having "delay" in sending the set of bytes[212].
OR how can i assign Set X bytes to one array and Set Y bytes to another array, so that i could append them??

How do you receive those bytes ? Why are you getting delays ? Be more explicit.

I just don't see what you are talking about. What is the problem with storing these values in an array ? The varying size ? Then you can use a vector from the STL, it will let you add and retrieve elements in the array without worying about the size.

BTW, use the pre or code tags when you post code.

To turn off:
1. Select "Project->Settings" from menu.
2. Select "C/C++" tab.
3. In the "Preprocesor definitions" edit:
   3a. Remove "_UNICODE" and "UNICODE".
   3b. Add "_MSCS".

Hi,

Is there any way to disable the default error messages using ADO & MFC in the try catch structure ? Because now i receive two (2) error dialog messages. One from the OLEDB and one that belongs to the application custom error.

Regards,
