Re: Converting to VARIANT DATE type from time_t

Here's one way to do it:

Convert from time_t to FILETIME like this (Q167296):

void UnixTimeToFileTime(time_t t, LPFILETIME pft)
{
// Note that LONGLONG is a 64-bit value
LONGLONG ll;

ll = Int32x32To64(t, 10000000) + 116444736000000000;
pft->dwLowDateTime = (DWORD)ll;
pft->dwHighDateTime = ll >> 32;
}

Then, convert from FILETIME to SYSTEMTIME by calling FileTimeToSystemTime().

Then, convert from SYSTEMTIME to VARIANT TIME by calling SystemTimeToVariantTime().

This is kind of like playing "Six Degrees of Kevin Bacon".

yah i know an installer will do that for me but i dont want this app to use an installer ... its static linked and has to be a single .exe file

i want to check if there is a start-menu shortcut and add one if not from within the exe

i know its prolly a no-brainer but i keep finding WSH references in msdn ... windows scripting host??? WTF | :WTF:

clues appreciated

GetModuleHandle(NULL) would give you the starting address of the process in the memory. The layout of the process is same in memory as on disk.

Font in CStatic control

I am making a multi language application and therefore prefer to add static text strings to dialogs by using CStatic::Create rather than the resource editor. When I do this I allways get a bold typeface. I want to have the same font as I get by using the resource editor. How can I achieve this?

Confused | :confused:

first off ... multi-language doesnt mean u have to do things the hard way ... use the resource editor for your captions ... when you change languages you simply make a new resource dll and load it at run time ... thats the 'preferred' way afaik

to set the font for controls on a dialog use the SetFont(...) on the dialog box window ... to override specific controls u should trap the OnCtlColor(...) message and do the stuff you want there

hmmmm

I am indeed making a new resource dll for other languages. But I put all my text strings in the string table and use LoadString() to show the strings in the CStatic controls. Hence the use of CStatic::Create(). Isn't that the right way? I know I can open the RC file as a text file and edit it, but that seems to be rather dodgy.

SetFont() takes a pointer to a new font. Is there an easy way to get a pointer to the standard font for static controls, like you do when you use SelectStockObject()?

Found it....

1. Give each static control a separate ID
2. Allocate a control variable to each of them (m_Static1)
3. Use m_Static1.SetWindowText((LPCSTR)string);

Thanks for your help anyway.

Adding performance counters

There is a good article in MSDN, titled:
"Instrumenting Windows NT Applications with Performance Monitor".

I have downloaded the samples and registered the counters.
However, the counters are not displayed in the monitor and an error code 1003 is displayed in the event viewer.
This is the error description:
"The object length of an object returned by Extensible Counter DLL "...D:\Work\PerfCounter1\ExtCountFinServer" for the "FinServer" service was not correct. The sum of the object lengths returned did not match the size of the buffer returned. Performance data returned by counter DLL will be not be returned in Perf Data Block. Count of objects returned is data DWORD 0. "

Could anyone, please, try this sample and check what is wrong?
How can i solve the problem?

Thanks,
Dudi

Formating text from a .txt file

1-Jun-02 22:42

Hi.

I'm trying to create a function which would load text into a array.

Like

Text[100][100]

I'm making a kind of phonebook, char Text[will hold the name][will hold the phone number]

I'm trying to create a function which will scan a text file and place the name of a person and the phone number of a person in the Array.

Ex:

text.txt

name: blah 1 phone: numbers 1
name: blah 2 phone: numbers 2
name: blah 3 phone: numbers 3
name: blah 4 phone: numbers 4

The function should scan the file, and add the name to the first part of the array, and the phone number to the last part of the array..

How could I do this?

You'll have to read line by line and parse it manually!!!

OK. You can use fopen to open the file. Then use fgets to read line by line.
For each line you'll need to parse out your fields. If you were using some fixed separator like say a comma, you could use strtok. But here you'd have to do some manual work Frown | :-(

You can use strchr and strstr.

i have got different images which i want to write using '0nDraw' function.i want to call these images from menu.what is the procedure to follow. Hmmm | :|

There is a hope for an honest error not for an icy perfection.

Use the appwizard to make handlers for each of the menu items, then set some member variable I'll call it "selectedimage" to a number one for each image. Once you've set the variable, then call Invalidate() (this will repaint the view and call OnDraw()). Then you just have a switch(selectedimage), and a case stament for each image:

class CMyView : public CView
{
public:
//------- Blah Blah (usual stuff) -------//

protected:
int selectedimage;
}

CMyView::CMyView()
{
   selectedimage = -1;
}

void CMyView::OnPicture1()
{
   selectedimage = 1;
   Invalidate();
}

void CMyView::OnDraw(CDC *dc)
{
   switch(selectedimage)
   {
   case 1:
      DrawImage1();
      break;
   case 2:
      etc...
      break;
   }
}

Hope thats helpful

Another Question

Hi There,
I'm in the process of writing an MFC MDI application. I would like to have views in a docking window - getting the views into the docking window is not a problem, but getting pointer to document etc. is proving a little tricky. I originally though the easiest way to solve my problem was simply use the CCreateContext which I thought would be stored in lpCreateStruct in OnCreate in the CMainFrame, but it seems because the app is MDI that lpCreateStruct has NULL in its lpCreateParams. This raises questions: 1. How do I get pointers to the document? 2. How can I get my docking view to respond when the active document changes? 3. is it possible, or would I be better of using SDI? Thanks for your time...

1. How do I get pointers to the document?

Say you have these classes:
Application class : CMyApp
Main frame class : CMainFrame
MDI child frame class : CChildFrame
Document class : CMyDoc

// to get the active document
CMyApp* pApp = (CMyApp*)AfxGetApp();
CMainFrame* pwnd = (CMainFrame*)pApp->GetMainWnd();
CChildFrame* pChild = (CChildFrame*) pwnd->MDIGetActive();
CMyDoc* pDoc = (CMyDoc*) pChild->GetActiveDocument();

Not pretty but you could wrap this in a function.

2. How can I get my docking view to respond when the active document changes?
I would try to override OnActivateView of the view class and do the processing based on which view (thus document) is being activated or deactivated.

3. would I be better off using SDI?
I would say Yes. MDI is nice but it can be a royal pain in the neck if you are a rookie like me trying to write a big app. Also I read somewhere that the average computer user finds multiple documents too confusing.
