Don't invent "incredible and magic solutions" whose sole effect is to disorient the user. Just make the dialog modal!

making dialog modal will work ? I do not think so since i am dealing with formview. All I want IS hide all edit control/buttons and rest of things when i click on dialog box.
thx for your time,
cheers from canada.

Let me paraphrase your talk:
"Entering the motorway the other side will work ?? I don think so: all I want to do is tell all those people coming against me to keep aside".
The problem is not the formview, but the bad design that has been done initially.
Even if you succeed in you intent, how many other application out there you know behaving that way? It is quite hard for a user that clicks somewhere and see something suddenly disappear to not be disoriented.
If you want to go in that direction think to disable the buttons, not to hide them.

I think you haven't understand the issue yet. Problems is not bad desgining neither formview nor dialog box, User won't be shocked when everything disappear since graph will be maximized and doubleclicks again will get it back to original size and most of the application DO HAVE the feature of doubleclicking even in mainwindow if you double click the header it will be maximized and double clicking back will make it look normal, but I am trying to do that in dialog boxes, It's not hard it just need little more time efford and better understanding of MFC ( WHICH I DO NOT HAVE SINCE I STARTED IT LEARNING BY MYSELF SINCE MONTH ONLY)
Yes disabling or hiding will not make much more diffrence since graph will be overlapped to them ( all i want is when i click just hide/disable/invisible or anything i just dont want them on formview LOL!)
thx for your reply. appericiate it, RESPECT 
cheers from canada.

GetDlgItem(ID_of button)->ShowWindow(SW_SHOW);//For show control
GetDlgItem(ID_of button)->ShowWindow(SW_HIDE);//For Hide control

thx for your reply. But i do not think that you have read my previous post, as i mentioned i have 100+ buttons so it's not a good idea to getdlgitem for all of them and hide them or show them because it would just make my code's complexity to 100+ which i do not want so if there is another way/idea to solve that problem please let me know.
thx again,
cheers from canada

if you have similar kind of control (button or editbox) then you can defined array of control variable.
after that, using for loop you can hide / show the control.
eg. CButton m_MyButton[200];
for(int i=0;i<200;i++)
{
m_MyButton[i].ShowWindow(SW_SHOW);
}

I managed to retrieve my desired icon from shell32.dll.
However the icon doesn't appear smooth! :S
HICON hItem = ExtractIcon(0, L"C:\\Windows\\system32\\shell32.dll", 8);
ImageList_AddIcon( himlIcons, hItem );
DestroyIcon(hItem);
Manifest Dependency fixed it!

You will run into trouble if you deploy on a machine with the os installed on a different drive or in a different folder.
You would be better off using SHGetFolderPath[^] with a nFolder value of CSIDL_WINDOWS. Then build your path from that. Have look at PathAppend[^] for instance.

What is this ? a paint like program ?
Me think you don't know what you want, how you want to do it.
Have a look at the MSDN scribble tutorial.
And good luck.
Watched code never compiles.

How do I use CPen with a width > 1; I using MM_ANISOTROPIC and my Viewport set to 1000,100 ? When I attempt do draw a random line, the width changes I believe because of the 10:1 scale that I set. How can I keep my viewport at 1000,100 and adjust the width on my line so that the width stays the same whether I draw a line horizontal, vertical or something in between?
|

|

I think there's little you might do. In other words, could you abandon the MM_ANISOTROPIC mode?

thank you, Pallini. i cannot abandon MM_ANISOGTROPIC, i must draw tow datas curves in the figure, they use the same time X axis, but they have different Y units and measurment ranges.
i hope i describe the questiong clearly,any more advices?

Still I think it is easier to adapt (i.e. scale) the curves than perform the 'pen trick' (since you require the pen writing also oblique lines).

Hi,
I have a dialog with image. I need to zoom in and zoom out the image according to slider.
Minimum zoom (-) will be 160*170 size image, at this point slider position will be 0.
But I can load image of any size then how to calculate slider postion based on image?

Didn't you preserve the aspect ratio?

What if the original image is smaller than your 160*170 minimum size?

If I keep aspect ration of 4:3 then how to do?
|
|
|
|

If you want to keep the original image aspect ratio then you may evaluate the minimum and maximum scale factors. The minimum: smallest image size with both dimensions still bigger than (or equal to) the correspondig ones of the minimum allowed rectangle. The maximum: biggest image size with both dimensions still smaller than (or equal to) the corrensponding ones of the maximum allowed rectangle. Please note, maybe minimum >= maximum in degenerated cases...) and set the slider accordingly.

Thank you,
Please suggest any article....
|
|
|
|

Why do you need an article?
Suppose your image has the following original dimensions {w,h}.
If the minimum allowd rectangle has {wmin,hmin} and the maximum has {wmax, hmax} then:
double smin = (double)wmin/w < hmin/h ? wmin/w : hmin/h;
double smax = (double)wmax/w > hmax/h ? wmax/w : hmax/h;
are the minimum and maximum scale factors (ofcourse you have to check in advance for division by zero - that is left as an exercise -).

First you determine the minimum and maximum zoom factors that you want, probably by comparing the actual image size with the available space.
Then you map minZoom and maxZoom to your minimum and maximum slider values, with minSlider=0 it would be as simple as:
zoom=minZoom + sliderValue*(maxZoom-minZoom)/maxSlider
if it is a linear relation you want.
check: fro sliderValue=0 it gives zoom=minZoom, and for sliderValue=maxSlider it gives zoom=maxZoom.

I have an application written on MS Visual C++ 6. In one of mu customers (WinXP Japanese) the application fails right after start. After studying crash dump i saw the following:
My app in its InitInstance intercepts several user32.dll functions: GetSysColor, GetSysColorBrush, DrawFrameControl. I needed this to implement my own skinning. The interception is performed by widely used 'code injection' method: I locate necessary function in loaded user32.dll and write into its begin byte 0xe9 (command 'jump near'), then 4 bytes - relative address of my intercept function. Before this operation I suspend all threads of my application.
This worked fine on lot of customer's PCs. But on one PC the application fails right after this intercept is done - after this myapp calls LoadString, and I get Access Violation. Call Stack is:
user32.dll!__LockResource@8()
user32.dll!_LoadStringOrError@20()
user32.dll!_LoadStringW@16()
mfc42u.dll!AfxLoadString()
mfc42u.dll!CString::LoadStringW()
<my code that calls CString::LoadStringW>
It turned out - this customer has installed a software named Humming Heads Security Platform (http://www.hummingheads.co.jp/). This is a security monitor that controls many aspects of every application's work. From the crash dump I see: several DLLs of this Humming Heads Security Platform are embedded into my process. My version is: it intercepts API functions too, and this lead to conflict with my interception (somehow). If I turn this interception off in my application, it does not fail. What can you say about:
what exactly happened?
what can I do?
will it help if I will do the API functions interception using other method known as 'Modification of import/export tables'?

I saw a near-identical issue over ten years ago with a product that I was working on at the time. We used a 3rd party library for something and it had implemented a message hook of some sort but was not passing the unhandled messages on to the next hook in line (ours).

Hi,
I have an editor in my application which has a find functionality implemented for it.The user will enter text in the editor and will try the Find option from menu.The problem is when I have n double byte characters(of japanese) in my text and say if I try to find an char or word which after the double byte chars then my search is displaced by n bytes.This issue happens only in japanese and the same application works fine in English.Going through the below blog which has a similar problem as that of mine I noticed that the problem is with the dependancy on ComCtrl 6 dll used in xp manifest theme.
http://www.insidercoding.com/post/2008/08/06/Visual-C2b2b-60-2b-XP-Manifest-3d3d-Problems.aspx
My application is also developed in vc6 and we use a manifest file for XP visual theme as below
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
version="1.0.0.0"
processorArchitecture="X86"
name="wm"
type="win32"/>
<description>Merely an XP test.</description>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
</requestedPrivileges>
</security>
</trustInfo>
<dependency>
<dependentAssembly>
<assemblyIdentity
type="win32"
name="Microsoft.Windows.Common-Controls"
version="6.0.0.0"
processorArchitecture="X86"
publicKeyToken="6595b64144ccf1df"
language="*"
/>
</dependentAssembly>
</dependency>
</assembly>
And I also cannot move my application to unicode. There are ASCII functions in my code.MFC by default supports MBCS.Even after placing _MBCS in project settings doesnt solve my problem. When I debug the below code I found the problem with lstrlen which is returning n chars extra for n double byte chars in my text to find.This happens only when I debug the code in japanese OS , the same works fine when I debug the same application in English OS.
static
int
FindStrPos( LPSTR lpSrc, LPSTR lpFind, BOOL bMatchCase )
{
LPSTR p;
int pos = -1, len;
char szFind[FIND_LEN];
LPSTR lpStr;
lstrcpy( szFind, lpFind);
if( !bMatchCase ) {
len = lstrlen(lpSrc)+1;
lpStr = (LPSTR)wwHeap_AllocPtr( hChunkWM,
(GMEM_MOVEABLE | GMEM_ZEROINIT), len );
if( lpStr ) {
_fmemcpy( lpStr, lpSrc, len );
_fstrupr( lpStr );
_fstrupr( (LPSTR)szFind );
p = _fstrstr( lpStr, (LPSTR)szFind );
if( p ) {
pos = p - lpStr;
}
wwHeap_FreePtr( hChunkWM, lpStr );
return( pos );
} else {
debug("Alloc failed compare case-sensitive");
}
}
p = _fstrstr( lpSrc, lpFind );
if( p )
pos = p - lpSrc;
return( pos );
}
I also used MBCS functions like _mbslen instead of lstrlen and _mbsstr instead of _fstrstr then _mbslen is returning accurate length in japanese and when while finding the difference between the search position and actual text pos the value of pos is again added with n bytes in japanese version for n double byte chars in Text.
I tried removing the manifest file as the unknown problem is with the dependancy of comcontrl dll version 6 for enabling Xp style but it is giving other problems in japanese.
Any suggestion would be helpful.
Thanks,
Satya
