hi,
i 've got a toolbar with a Combobox and 4 Buttons (pushbuttons), where i can (de)activate the combobox, whenever i want. I think it's easy possible, because in the CToolBar- derived class i 've got a handling member for this box, but even no member for one button.
So i added a CButton- member to the CToolBar- derived class to fit this problem and to (de)activate one button at same time, the combobox is (de)activated.
But it does'n t work :-/
Can anybody help me ?
thanks,
Aqua

I'm running Visual C++ .Net and have run into a problem when trying to open a file directly off of a CD-ROM or DVD drive. The files in question have no "last accessed time" which causes the program to return an error. For my purpose, I don't need to know if the file has ever been accessed, but I cannot seem to move past it without it returning an error. I have thought about temporarily moving the files to a harddrive first, however, some of these files can be anywhere from 400 megs to 2 gigs and things are time-critical.
right now, it blows out in line 130 of "filest.cpp" with the following line:
rStatus.m_atime = CTime(ftAccess);
anybody know how to get around this? Thanks for any and all help!

Hi Guys,
I have a Dialog Resource in my resourceEditor & I have created a class out of it say "C_TestDialog",which is derived from CDialog.
I want to place a Toolbar control in this dialog. So I have added a "ToolBarcontrol" also in my resourceEditor.
Now If I take my ClassWizard,& select the "C_TestDialog" under class name.In the "ObjectIDs" section I see my classname & in the Messages column,I see all of the events,messages etc of this class.
Now What I need now is,How can I include my "toolbarcontrol" also inside the ObjectIDs section,under the className "C_TestDialog",so that I can see all the messages related to the toolbar control.
RightNow,If I select my toolBarcontrol(IDR_SelectToolBar) inside the ObjectIDs section,I see only 2 messages - "COMMAND" & "UPDATE_COMMAND_UI".
Iam creating my toolbar as follows:
CRect toolbarSize(20,20,300,50);
//m_toolBarCtrl is the member varibale of type C_ToolBarCtrl--
which is a member of C_TestDialog class.
m_toolBarCtrl.Create(WS_CHILD|TBSTYLE_FLAT,toolbarSize,this,IDR_SelectToolBar);
m_toolBarCtrl.AddBitmap(1,IDB_BITMAP1);
TBBUTTON tb[2];
// Index of new button image.
tb[0].iBitmap = 0;
// Setting button state
tb[0].fsState = TBSTATE_ENABLED;
// Setting button style
tb[0].fsStyle = TBSTYLE_BUTTON;
tb[0].dwData = 0;
tb[0].iString = NULL;
m_toolBarCtrl.AddButtons(1,tb);
m_toolBarCtrl.ShowWindow(true);
Note:
Don't want to create a class derived from CToolBarCtrl.Want to access the Messages of the "toolbar" from my C_TestDialogClass.(For eg.- when the user clicks on the toolbar at runtime,I want this event to be trapped inside my C_TestDialog class)
Any Help is appreciated.
Thanks...

with the help of a c++ 6 control i get hotkey information in the form of a DWORD (it may be f.e. ctrl+s)
DWORD CHotKeyCtrl.GetHotKey();
how to extract information so that this DWORD is comparable to a WPARAM
in the message queue, if a key is pressed i get a WPARAM with information in it about the key being pressed
I just want to know how to compare the dword to the wparam
(HIWORD? LOWORD? <- i am a prog-n00b plz easy language)
|
|
|
|
|
To extract information from the return value of CHotKeyCtrl.GetHotKey() use HIWORD and LOWORD macros.
wVirtualKeyCode=LOWORD(GetHotKey());<br />
wModifiers=HIWORD(GetHotKey());
To create WPARAM use MAKEWPARAM macro: MAKEWPARAM(wVirtualKeyCode,wModifiers)
To compare DWORD to WPARAM use: if(wParam==(WPARAM)dwValue)
Regards,
Andrzej Markowski

I think that's the output for a particular file you're building. For .cpp/.c etc I don't think you have a lot of choice. For the exe/dll etc, I think it's whatever you specify in the output for the linker settings.

For MANY of the project files:
Go to Project Menu, Settings Menu Item, Project Settings General Tab, change OUTPUT FILES destination folder.
If you just want EXE to go somewhere else:
Go to Project Menu, Settings Menu Item, Project Settings Link Tab, Category General, change path for OUTPUT FILE NAME.

I have two double pointers. one is a content of the structure and other is pointer to the structure.
I initiate these double pointers as you see in the code. but now I have a problem with deleting these pointes.
how can I delete the double pointer included with structure and double pointer points to structur.
Thank you in advance.

Example with the m_pGrpConst pointer:
First delete all the pointers inside the structure:
for (int i=0;i<200;i++)
delete[] m_pGrpConst[i];
Then delete the pointers that point to these desallocated pointers:
delete[] m_pGrpConst;

Add a member function to your structure that deletes the memory allocated for the structure. But first you need to know the size of the array, so when you create your structure, maybe add also a member function that will allocate the memory for you (and store the size), so you'll be able to delete ot later.
I think also that you need maybe to revise a part of your code because this is quite heavy and this won't be very easy to debug... In general using pointers to pointers to structure that contains pointers to pointers to string, when you can avoid this, avoid it  .
The general rule for deleting memory is: every new must have is own delete. When allocating arrays of arrays of arrays ...(doesn't matter how many dimensions), the last allocated array must be desallocated first.
Hope this helps

Look in the controls section of CP - there are static controls that do exactly this.

CP is wisdom, grasshopper.
Have a look here[^]. A few of the controls will do what you wish, however I've used the CLabel control in the past and have had no problems so far.

Does anybody know how to choose a particular screensaver and disable the combo box in the control panel to prevent the user from choosing another one ?

If you're asking how to do this programmatically in VC++, I'm not sure. However there is a setting inside Group Polcy (gpedit.msc) that would accomplish the same thing. Hope this helps.

hi,
Iam using a barcode reader which reads barcodes into any open windows
text,excel files.
the thing is, iam catching this barcode text into an edit box.
but i have found there is no way to tell wether the edit box is filled
by barcode reader or user typed into it.
the barcode reader has no driver and just reads and displays text
inside an open document/editbox.
by debugging, i have seen the reader generates WM_KEYDOwn messages
which is same as when a keyboard is physically pressed.
can any one tell me how to tell if a user has actually pressed the keyboard
instead of a virtual message generation.
Rgds,
Mahesh

Look at MW_KEYDOWN, WM_CHAR, and WM_KEYUP - read then *all* carefully and that should give you what you need.
