A very handy utility that is part of the WinOS is charmap. It will show you the characters available for each font, as well as the key combo to produce that character.
onwards and upwards...

Yo,
Say I have a mission critical program. I want to periodcally check that it is still running possibly using cgi show a status
on a web page or at least alert someone if it ceases running. Is the best way to write a small service which checks if the process
is running? What do others think. Is there a simpler solution.
Regards,
Alfonce

for a small-to-medium WTL application, I'm looking for a serialization library. Typical files will be <100K, but the data structure is fairly complex. Text or binary doesn't matter.
Requirements: free (non-GPL), low runtime dependencies, simple to use.
Any takers?

Haven't used it myself, but given the link in your sig you might want to try this (if you haven't already). Looks pretty flexible...

I am stumpped
I have a tree control I am filling with
// insert into the selected tree item
tvinsert.hParent=this->GetCurrentItem(bLocal); tvinsert.hInsertAfter=TVI_LAST; tvinsert.item.mask=TVIF_TEXT|TVIF_IMAGE|TVIF_SELECTEDIMAGE|TVIF_CHILDREN; tvinsert.item.pszText=new_name.GetBuffer(0); tvinsert.item.iImage=f;
tvinsert.item.iSelectedImage=g;
HTREEITEM a = TreeView_InsertItem(tmpTree->m_hWnd, &tvinsert);
but it doesn't show a plus (+) sign.
// if I add
tvinsert.hParent=a; tvinsert.hInsertAfter=TVI_LAST; tvinsert.item.mask=TVIF_TEXT|TVIF_IMAGE|TVIF_SELECTEDIMAGE|TVIF_CHILDREN; tvinsert.item.pszText="first sub item"; tvinsert.item.iImage=f;
tvinsert.item.iSelectedImage=g;
HTREEITEM b = TreeView_InsertItem(tmpTree->m_hWnd, &tvinsert);
// still no plus
// if i add
tvinsert.hParent=b; tvinsert.hInsertAfter=TVI_LAST; tvinsert.item.mask=TVIF_TEXT|TVIF_IMAGE|TVIF_SELECTEDIMAGE|TVIF_CHILDREN; tvinsert.item.pszText="sub to sub item"; tvinsert.item.iImage=f;
tvinsert.item.iSelectedImage=g;
HTREEITEM a = TreeView_InsertItem(tmpTree->m_hWnd, &tvinsert);
the item now has a plus sign with both subs, one under the other....
any helps really, really appreciated

Since you have the TVIF_CHILDREN mask bit set, you need to set the tvitem.item.cChildren flag. In debug mode, the flag would normally be set to zero indicating there are no children - so, you need to set the flag in the root and child item to 1 and the grandchild to 0.
This should result in
- ROOT (a)
- CHILD (b)
GRANDCHILD (c)
when expanded.

So what does it show? Is it off by one? Does the while loop not find any ASCII 12 characters? Remember that "page eject" in PCL can be any of the following commands:
RESET (EcE)
PAGE SIZE (Ec&l#A)
PAGE LENGTH (Ec&l#P)
ORIENTATION CHANGE (Ec&l#0)
PAPER SOURCE CONTROL SEQUENCE (Ec&l0H) with a value of zero
PAPER SOURCE (Ec&l#H)

This program should to show the number of pages a file it be printed in format HP-PCL.
Does the while loop not find any ASCII 12 characters?
No, no finds.

How about using fopen(InputFileName, "rb") instead?

If you could provide me with a link to a .pcl file, I can provide you with a code snippet to do what you require.

Ok, Thank´s!!
I write a text file in "Notepad" and send to print to file in a PCL5 Printer Driver. Then, I execute the program for count pages pcl and it does not work.

How do I check if "\\Computer42" exists.
I want to check before I work on some files that are located on a share on that machine.
|
|
|
|
|
How about NetServerGetInfo(L"Computer42", 100, ...)? It will return ERROR_BAD_NETPATH if the machine does not exist.

Currently I have drag recntangle working but problem occurs while I have Left mouse click down and scroll at the same time. At that point it would loose track of the mouse location because it doesn't include scroll in to the factor.
2 ways I can see to do this
In OnMouseMove track where the scroll window is moving. But the problem with that is Mouse isn't moving so it's not calling the function.
Or
In OnKeyDown update the movling location. The only problem I see with that there is no CPoint mouse location passed over to OnKeyDown and I have to capture OnMouseWheel also.

Hello everbody,
I created a hashtable in a file to search the contents of some database.
I use the standard operations (fseek, fread etc) to access the file.
Everything works ok, as long as my indexfile is read from harddisk. (There are more then 200000 entry in it and it takes less then a second to search for an specific entry).
However, if i put this on cd-rom its about 2800% !!! slower. Especially if my search returns more then one result.
Is there anyone around here who knows how to optimize a file for cd-rom access?
Sorry for my english, what i am trying to say is:
How has i file to be constructed so that it can be read from cd-rom real fast?
Any help would be highly appreciated.

So every second of HDD time equates to 29 seconds of CD time? It's true that CD-ROM drives will be slower than HD drives, but how much slower depends on a lot of factors. I suggest reading this guide to see what all is going on.

Every time you ask for data on a CD that is not right after the last data you asked for the CD will need 1 second to position. So you need to figure out how you can read your table in order.
Suggestion: Get Knuth's "The art of computer programing" out, and look for the sections on searching from tape.
