have you tried sending MCI_SEEK with MCI_SEEK_TO_START?

"Things that don't work on my system (Win 98) all relate to the date based patches (WFP is my only date based patch).
- When I set the date, the messages indicate that the date based files have been copied into SIMPATCH, but they actually haven't been. Eg. When I set the date the 161001, I assume that all the files in the 13 WFPdate folders from 150801 to 161001 should be copied into DATA/SIMPATCH, but by checking in the SIMPATCH folder I can see that non of these date based files are there.
- The 'date:browse' button still doesn't seem to work. When clicked, nothing happens. Funny because the other browse button (for the .exe) works fine. I have to enter date manually.
- The 'modify campaign' button doesn't seem work for me either. When clicked, the date dialog box just disappears."
What he's talking about has to do with an MFC application, RBPatch, which I have been working on. The issues he's having are related to a CFileDialog object, and some CopyFile + FindXFile operations. People running WinXP or WinME have absolutely no issues, but there have been some people running 98 and 95 OSR2 having the exact same issues.
Any ideas?

How can I load/get/retrieve the 16x16 pxls icon (Information/Error/Question) that I see in the balloon-tooltip what-so-ever it name is (It shows me my connection speed in the system tray when connected)? Its size is important, must be 16x16.
10x.

You can retrieve it manually: When the icon is being shown, press the key "Print Screen". Launch MSPaint, paste into it, cut the icon and paste it into your resources editor.

Man, I wanna have no resources in my class. I worked kinda hard to create the
icons, pixel by pixel in a matrix...(feels stupid, but hey, you know me...). I wanna load what exists. Me wish not invent no wheel...Man. 
Any other ideas?!

The icon size (used CDC::DrawIcon(...)) is 32x32.
How can I get the 16x16 icon???
m_hIcon = (<font color=blue>HICON</font>)LoadImage(<font color=blue>NULL</font>, MAKEINTRESOURCE(OIC_INFORMATION), IMAGE_ICON, 16, 16, LR_DEFAULTCOLOR|LR_SHARED));
CPaintDC dc(...);
dc.DrawIcon(0, 0, m_hIcon); //Draws 32x32 icon!

the only solution i've found is to create a 16x16 image list, add the icon to that and then use the imagelist draw functions for the drawing.
somehow, imagelists know how to extract the correct size of icon.

This is a newbie question but I somehow cannot get this part of my code to work. I have the user input into a character array of unspecified size like this:
char *cArray1 = new char[];<br />
cin >> cArray1;
and then when I try to calculate how many elements is in the array, the sizeof() function always returns 4 for some reason. I'm calculating the number of elements by the following.
size_t iArraySize = sizeof(cArray1)/sizeof(*cArray1);
(I also tried int as the datatype instead of size_t but no luck)
I always get 4 as the return cause sizeof(cArray1) always gives me 4 and 4/1=4.
I think sizeof() cannot be used with dynamically allocated arrays, so is there anyways to do this? 
Please give me some advice how so solve this question...
Thanks!

Use strlen function (don't forget to include <string.h>)!

cArray1 is a pointer, not an array. It points at the first element of an array (null-terminated string). It is 4, because in Win32 pointers are 32-bit (4 * 8 bits - that's why you get 4)!

Use std::vector and its size() member instead.

The only reason you get 4 (4 bytes) for sizeof (cArray1) is that sizeof actually measures the size of the cArray1, which is a pointer. And as you probably know.... a size of a pointer is 4 bytes (in your compiler anyway...).
char *cArray1 = new char[]; //very bad idea! No array size specified.
instead, use fixed sized buffer: char cArray1[ARR_SIZE];
This one you can measure:
size_t iArraySize = sizeof (cArray1)/sizeof(*cArray1);

Ok, I really feel dumb now hehe. I was out of code for a while so I totally overlooked that fact about the operator referring to the pointer. Thanks for the help. I just used strlen and it works fine. Thanks for all the help!

Well...
Your array is actually a pointer, so the function sizeof() will always return
4 because that's the size of a pointer. Getting the number of elements in an
array is a different thing.
Now, I think you should do this some other way. First of all, why would you want to give the user unlimited input length? Just specify a limit and save
yourself a headache.
Second, maybe it could help to know the length of the array before allocating any memory... but, well, what is it you want to do?

Hi all,
If I use VS.NET to create a dialog application and say I add a ListCtrl with the designer and set the style to REPORT.
So where is this information stored, does the designer generate code? For example I would look for some code in my project containing LVS_REPORT:
m_myListCtrl.Create(<br />
WS_CHILD|WS_VISIBLE|WS_BORDER|LVS_REPORT,<br />
CRect(10,10,400,200), pParentWnd, 1);
but that code does not exist in my project!
Thanks in advance.

There's no generated code. The dialog layout is defined by so-called 'dialog template' stored in program resources. When you invoke dialog box, Win32 API (not MFC) creates the dialog box and populates it with controls.
The code you'll see in MFC app is responsible for creating CWnd-derived objects mapped to their Win32 API counterparts (HWNDs). Look in DoDataExchange for this.

if u want to just change the style do this:
m_cListCtrl.ModifyStyle(0, LVS_REPORT);
in the constuctor or initdialog();:

Hi
another question
why don't the following code compile?
extern CFile cfile;
void *data;
CFile::Open(m_Pathname1,modeRead);
data = cfile.Read(0,cfile.GetLength());
i get the error:
error C2440: '=' : cannot convert from 'unsigned int' to 'void *'
Conversion from integral type to pointer type requires einterpret_cast, C-style cast or function-style cast
(BTW, what does extern do! Otherwise CFile::Read(etc) also works)
thanks

extern CFile cfile;
CFile::Open(m_Pathname1,modeRead);
DWORD dwFileLength = cfile.GetLength();
BYTE *data = new BYTE[dwFileLength];
DWORD dwBytesRed = cfile.Read(data,dwFileLength);

tx, this works
what does BYTE *data = new BYTE[dwFileLength] do?
|
|
|
|

It allocates memory to hold data from the file. When you will finish using it, then you have to free that memory with:
delete [] data;
I think you have to read little bit more about C++.
