Hi,
I need to execute my project exe through command prompt.
1) If I give path of exe in command prompt(one argument) then it should execute GUI version of Project.

2) If I give two arguments in command prompt then it should execute CLI version of Project.

How can I get command line arguments In MFC.In windows programming we are having

int _tmain(int argc, _TCHAR* argv[]) main function.But how can I do it in MFC.

You have access to __argc and __argv whether you use MFC or not. Also check out the app's m_lpCmdLine member.

there are a bunch of command line parser classes out there, to take care of splitting the cmd line into flags and options.

for example: CCmdLine - command line parser[^]

Sliderbar problem

Hi friends,
I've encountered a problem using Sliderbar in my MFC program.
I've set the MaxRange to 86400 (for example: m_slider1.SetRange(0, 86400);), but once I want to change the position of it and handle the new position in the OnHScroll(), I would receive incorrect position. Now, I would like to know whether there is any limitation for setting Maximum range to the slider bar or not?

Thanks in advance.

What is incorrect? How are you verifying this?

For example, I set the sliderbar to the end point and I expect to get value of Maximum (here 86400), but I don't see it and I watched 32423 (a value lower than maximim).

The nPos variable is actually a short int because Windows sends the position in the high word of the WM_HSCROLL message's WPARAM value. Instead, call GetScrollInfo(&scrollInfo, SIF_TRACKPOS) in your OnHScroll() handler.

Strange Line-Selecting Behaviour in CRichEditCtrl [modified]

badhad2-Jun-09 1:51

Hello,

I do a whole line selection in a CRichEditCtrl (Version 2.0, embedded in a CRichEditView) by the following

1. Caret is left on the line start of a empty or not empty line with at least 2 lines following after this line
2. Select whole line with Shift + Down-arrow (only one key press)

=> There are differences in the selection behaviour depending on the following line (the line after the line that has the caret before selecting) beeing empty or not.

- All seems to be ok when the second line is NOT EMPTY => only ONE line is shown as selected.
- But when the second line is EMPTY => TWO lines are shown as selected after one key-press what is very unusual for me.

Example:

(the "#" stands for the blue selection, the "|" is the caret position before the line selection)

Roll eyes | :rolleyes:

Normal behaviour:

line n:	"|line with caret at start"
line n+1:	"not empty line below"
line n+2:	"..."

Shift+Down => Selection looks like this:

line n:	"########################"	(one line selected)
line n+1:	"not empty line below"
line n+2:	"..."

Strange behaviour:

line n:	"|line with caret at start"
line n+1:	""				(empty line )
line n+2:	"..."

Shift+Down => Selection looks like this:

line n:	"########################"	(line is selected)
line n+1:	"#"				(following empty line is selected also !?)
line n+2:	"..."

I would like to have a behaviour like the Visual Studio editor e.g. where with Shift+DOWN only one line is selected in every case. Does somebody know how I can achive this? (The CEdit-class for example does not have this selection behaviour.)

Or is there a reason for this behaviour?

Thank you in advance for your ideas
Sebastian

thank you
