Sliderbar Problem

Hi,

I am new to windows programming. In my code I would require to change the slider bar position (I am actually invoking the sliderbar from UI using win32 API, so I donot have source code of the application), which I have accomplished by sending message.

::SendMessage( aControlHWnd, TBM_SETPOS, (WPARAM) (BOOL) TRUE, (LPARAM)(LONG) aPosition );

The problem is with the updation of the window according to the new sliderbar position, I mean, when I change the position of the sliderbar it is changed visually, but the corresponding values in other objects (like textbox showing the value related to this sliderbar) are not updated.
To accomplish this I tried

::NotifyWinEvent( EVENT_OBJECT_VALUECHANGE, theDialogHWnd, OBJID_HSCROLL, CHILDID_SELF );

where theDialogHWnd is the handle for the dialog window containing the sliderbar and the textbox, but it didn't work. I am not sure if the parameters I am using are correct, or the event I am trying to notify, or may be my approach to the problem itself is wrong. I do understand that this can be easily accomplished by sending a keyboard or mouse event, but I am tryin not to use it.

Any help would be greatly appriciated.

Thanks.

When slider bars are moved they post either a WM_HSCROLL or a WM_VSCROLL to its parent. Try posting these messages to the parent window of the slider bar. To determine which message should be sent check the slider control for the style TBS_VERT.

See if something like this works:

int iPos = m_slider->GetPos();
if (m_slider->GetStyle() & TBS_VERT)
pWnd->PostMessage(WM_VSCROLL, (WPARAM)((iPos << 16) | SB_THUMBPOSITION), (LPARAM)NULL);
else
pWnd->PostMessage(WM_HSCROLL, (WPARAM)((iPos << 16) | SB_THUMBPOSITION), (LPARAM)NULL);

I want to know how can i make Intelliegnt Connectors,like those in MS Visio that connect 2 or more blocks and when the blocks are moved, the connectors position themselves accordingly without interferring with any other block.
Is it possible to make such connectors using VC++? I need this as i have to do a the same for my project.

Pls help

Hi, it can be possible, but it will be difficult.

I would make it by setting the points where you can connect the object in an array/structure, then use some regions to know if the mouse is approaching to one of them to make the point visible when necessary and using its coordinates by clicking when it is visible.

Afterwards for the lines... this will be pretty hard (I think), at the beggining you should determine which point of your object is being used to start the line. Make a short line in this direction (if the point is at the top then a short line to north, if the point is at left, then a short line to west, and so on...). Then give priorities in directions (I mean go to the north if the object is in the lower part of the screen, go to the right if the object is on the left...). Once you have the beggining of the line, you should have a register of positions for the lines from left to right, from top to bottom (like a screen grid) and go through checking where is the next free place to draw the connection.

I can not give you any code, but the idea may be like that.

Shortly: Have a matrix to save the position of gridlines of the workspace, check where the connector is starting and go through taking dinamically the first free gridline you find towards the end of the connector. (if end is below, going down, if end is above, going up and so on)

Greetings.

Hi Nelek,

Thnx for the suggestion..
I guess something like screen grid and maintaining which gridline is free or occupied should work but i feel it will be a lot of work..!!
There may be so many blocks on the screen and no connection line should pass through any of them... Sigh | :sigh:

Also i want to select a connector line and delete it...I was making lines using GDI but how to handle mouse events on these lines..? Do i have to maintain the coordinates of each line also and then check if clicked point is on any line...??

i really wonder how it works in Visio... Confused | :confused:

I would try to start with this approach meanwhile if some other solution comes to your mind , pls do share..

Regards

I think it will be easier if you create 2 matrix of points (one for each direction: Vert and Horz) with the index of the points (I mean: 00, 01, 02.. 10, 11, 12.. m0, m1..mn).

Afterwards you can correct the position of the click with a round to your grid unit/separation between lines (5 pixels for example). And determine the indexes of the line ends.

But yes, it will be a lot of work and considerations. The lines can be saved in a CList (take a look to my article "An addition to the Smart List" and the previous one I based mine), this will allow you to save structures or another lists to sae the corners of the lines. But you will need to check all to determine which line are you chosing to delete or modify.

I don't know how visio makes it, but I guess should be something like that.

I would make a class for the lines with methodes like IsPointInLine (CPoint point) to pass the position of the click or the mouse movement, variables like CPoint cpStart, cpEnd a list of corners... and so on.

I'm sorry not being more concret, but I will try to help you as long as I can (at least with the ideas or algorithms).

If I have another idea I will say it.

EDIT: To improve methodes I would make the list with objects but all the methodes with pointers.

Greetings.

Unable to start program on VC++

Hi there,

My problem is that an exe file I build with VS 2005 (Professional
Edition) simply refuses to run on other computers. In fact it runs only
on machines with VS 2005 (Professional Edition) installed; on other
machines it simply says
I've checked for DLLs the program loads but it seems that they exsist on
these computers too.
If I try to start this program from from VS 2005 Express Edition, a
console window appears with this message:
Unable to start program 'E:\project\Kamicopy\Sconverter.exe'. This application has failed to start because the application configuration is incorrect.
Review the manifest file for possible errors. Reinstalling the
application may fix this problem. For more details, please see the
application event log.
Frown | :(

---------------------------
OK

How can I fix this?

Rather sounds like the target computers are missing the updated C run time

Three step fix this error:
Step 1. Update window xp2
Step 2. Download vcredist_x86.exe and vc2005sp1_redist_x86.exe and run it.
Step 3. Press Alt+F7 click configuration change "debug" -> "Release"
Thanks all for support.
