Based on Sujan's comment, could it be that getline() is positioning the file pointer past the end of the file such that the append operation fails?

I have an application developed using CRichEditCtrl, how can line numbers be added into such an application.
The cursor should not actually come to the part where the line numbers are displayed.

Hello,

I am developing a new product and I often find myself asking if I should use this control or the other... Is the use of many DialogBox better of one single multipage one? Should I place a lot of comments inside Dialogs to help users to understand the meaning?

I know that it's all very subjective but does exist a definitive Windows UI Style Guide to give my product the best/modern look & feel? OMG | :OMG:

...but this guide does not contain suggestions, only explanations...

Nothing that suggest the best way connect with Windows users?

Maybe something more close to "usability tests"? Confused | :confused:

There is no best way -- UI design is really an art.

My best recommendation to you, is just do your best. Then budget some time into your project for Usability/UI review.

Find a few people in your target market, ask em to use your product without any coaching or documentation -- see if they can figure it out. Video tape them doing that....

The adjust it and try again.

Peter,

In general do you prefer SDI or MDI applications? I remember to read in the past that microsoft suggest SDI model because for the users is more easy to understand.

If only I could find that URL... It was something from microsoft... Cry | :((

I prefer SDI.

Use MDI only if you have no other choice. There aren't that many MDI applications out there anymore. Excel and Visual Studio are good MDI applications, but in that sense MDI makes good sense.

Word is no longer MDI. Why? Because it doesn't make sense to edit unrelated documents in the same window....

For Excel, MDI makes a little more sense -- as does in Visual Studio.

Hmmm, it suggests that:

Buttons be 14x50 DLUs

4 DLUs be used to separate buttons and controls

Small toolbar buttons be 16x16 pixels

A group box be used to group related controls

Vertical fields should be aligned by their left edges

Command buttons should be aligned at the top right

Every file your program creates should have a registered file type

Copying files into the Windows folder or its System subfolder should be avoided

When you design for network access, support standard conventions such as UNC

Abbreviations be avoided unless the abbreviated form is as familiar to your users as the full word or phrase

One of two styles of capitalization be used: book title, or sentence-style

Numbers be aligned at the decimal point

Icons should be supplied in 16-color and 256-color versions

A pointer's hot spot location should be intuitive
...

A book you might consider is here.

Hi

I have a CButton on a dialog. On click of the button, I want to create another dialog and poisition it just below the CButton. I tried using GetWindowPlacement on click of button on the first dialog and SetWindowPlacement in OnInitDialog function of the second dialog, but I am not able to position the second dialog correctly. Can anyone please help me to do this.

Thanks
Madhavi.

SetWindowPos() may be better.

moreover, use a CRect to get the position of you button like this (thanks to Chris Maunder for his Unclickable button[^]) :

CWnd* pParent = GetParent();
<font color=#0000FF>if</font> (!pParent) pParent = GetDesktopWindow();
<font color=#008000>//...</font>
CRect ButtonRect;                         <font color=#008000>// Button Dimensions (Parent coords)</font>
GetWindowRect(ButtonRect);
pParent->ScreenToClient(ButtonRect);
CPoint Center = ButtonRect.CenterPoint(); <font color=#008000>// Center of button (parent coords)</font>

Hi Cpians,
In one of my project, I need signed Key Algo. As crypto always go miles over my head. So if any provide me nice pointer or source code.

Let me explain looking for this type of thing. Using user name (any name) I generate the Key, that key I verify in the component with Public key. If it is ok, I will allow user to use my Component.

Here only I looking for some algorithm where I can put private Key & Username and in return it give me User Key, Public key.

Any Help is Greatly Appreciated

Currently I have a call back function that will send info from the library to the application throughout a certain period of time. The problem I've encountered is that there is no reaction on the button that is base on the application. Confused | :confused:

On Visual C++ 6.0, how to I identify a user who is having what kind of privileges? (i.e admin privilege, etc)

Hi All,

I have an function exported from a dll:
HRESULT FuncName(LPWSTR *, LPSTR * *, ULONG);

When I link to this function from the client program, it gives link error(Unresolved externals.

When I change the first Parameter of the function to LPSTR* instead of LPWSTR*, it works fine.
Why LPWSTR is not working? Any idea how to solve the issue.
I am using VS.Net 2003 and porting some VS6 projects to VS.Net.
Both these dll and client are working perfectly fine in vc6

Thanks...
