You can capture link-based events (it may be as easy as handing the Navigate and similar events) to enforce their behavior. For example, you can cancel them, force them into a new window, or force them into a specific window. IIRC, there is a target parameter that specifies the intended target for the link.

Tool tip on a button

Hi All,
In my application I have a button with an Icon. I load the icon on the button using the LoadImage API and then SetIcon(). The button does not have it's owner draw property set to true, only it's Icon Property is set to true. When the user hovers the button with the mouse a tool tip is shown. The problem is that, the tooltip is only shown when the icon is shown in the disabled state. When the icon is in the enabled state the tooltip is seen only if the mouse is hovering on the corner of the button.
Can anyone help or provide some ideas on how to show the Tooptip when the user is hovering over the button with an icon?
PS: I am not allowed to subclass the button control Frown | :(

Atleast by adding a new class to the application's code base.

Somethings seem HARD to do, until we know how to do them.

   This does not sound like standard button behavior to me. I would be interested to know how the tooltips are implemented. Is the tooltip control having events passed to it, or is it hooking/subclassing the button control itself (TTF_SUBCLASS)?

   I have done icon buttons like this many times with tooltips and never had a problem like you are describing, other than when the button is disabled, the tooltip is not normally shown. So I think some special tooltip handling is being done which is broken.

   Peace!

The tool tips are being implemented by passing the events.

IActiveScript return value from event function ?

achainard18-Jun-07 1:22

Hi,

I use IActiveScript (JScript) in my application (MFC ActiveX VC2003), i try to retrieve argument modified or "return value" from java function, but it don't work...

The java function is call the argument is good, but the variable modification in java do not appear in c++ code when return ?

Thanks,

Arnaud,

<code>
// Call initialize function (call javascript function).
long Result = m_pScript -> FireOnInitialize ();

// Idl declaration.
[id(1), helpstring("method FireOnInitialize")]
void OnInitialize ([out] long * pResult );

// Event map from cpp.
BEGIN_EVENT_MAP(CTestCtrl::CTestScript, CScript)
EVENT_CUSTOM("OnInitialize", FireOnInitialize, VTS_PI4)
END_EVENT_MAP()

// Function from h.
LONG FireOnInitialize ()
{
LONG Result = 5;

// Call event 1.
FireEvent ( 1L, EVENT_PARAM(VTS_PI4), &Result );

return Result;
};

// Function from js.
function Script::OnInitialize ( value )
{
Display ( "OnInitialize" )

if ( value == 5 )
{
Display ( "5" );
}
else
{
Display ( "?" );
}

value = 3;

// Every things ok.
return 2;
}
</code>

   I am not sure if you are seeing a limitation of Connection Points themselves in the IActiveScript scripting implementation, or a limitation of the JavaScript script engine itself. You can try to see if the same thing happens with a VBAScript/VBA event-recipient to be sure...

   But in general connection points are not a reliable way to return information from an event recipient, especially when multiple event receivers are involved, or if a poor implementation is forwarding the event to something else, because it might not be forwarding the return value correctly.

   Peace!

Is it possible to use the handle returned by GetClusterResourceKey and and pass it to RegQueryValueEx to read the data values ?

i have done but RegQueryValueEx returns ans error code of 6, that is for INVALID HANDLE...

Otherwise please tell me how to read the data values from the handle returned GetClusterResourceKey ?

Look up the documentation for that function, you will find the related ones like ClusterRegQueryValue(...).

Locking a dialog in place

Hi again,

I have a question regarding a locking a dialog in place. I have a dialog box that is maximised to occupy thw whole screen. I wish to make it so that the operator cannot minimise it, or move it. Effectively it will become the desktop - is there a way to do this? Other applications can be opend over it, but when they are closed, or minimised, the desktop will always revert back to the main app. Any suggestions - Thanks for looking

In the resource editor, uncheck the buttons support minimize and maximize. Then use ShowWindow (WS_MAXIMIZED) by creating the dialog, or take the dimensions of the desktop and use SetWindowPos () to this sizes.

Greetings.

Reading PDB/EXE files

Hello,

How can I find out value of a constant (was decalerd as #define in the h file of the exe), if I only have the pdb and the exe file ?

I have found the ascii name of the constant in the pdb file, but couldn't figure out where the value resides.

Thanks,
Eyal

Re: Reading PDB/EXE files

I do not think that you can (at least not with the C/C++ implementations I am familiar with)...

When you use #define, the pre-processor replaces the defined identifier with its value. So, if you have the following:

// In The .H File...
#define   <code>THE_VALUE   42</code>
 
// In The .CPP File...
for( int iValue = 0; iValue < <code>THE_VALUE</code>; iValue++ )
{
    // Loop Body...
}

Then you cannot scan the EXE file for THE_VALUE because the pre-processor will replace it with the constant value 42, so after the pre-processing phase, the C file actually looks more like this:

for( int iValue = 0; iValue < <big><code>42</code></big>; iValue++ )
{
    // Loop Body...
}

Peace!

Re: Reading PDB/EXE files

Berlus18-Jun-07 2:14

Berlus

18-Jun-07 2:14

OK,
So the pdb only conatins the name of the define and not the value itself ?

Re: Reading PDB/EXE files

James R. Twine18-Jun-07 2:23

James R. Twine

18-Jun-07 2:23

   I am not certain about the PDB, but at first blush I would not expect it to contain #defined values.

   I might expect to see values that were set up using something like const int THE_VALUE=42 because they are handled by the C++ compiler (not the pre-processor), however. I could be wrong on both counts...

   Peace!
