Try creating the exe in release mode..

If that too fail use Dependecny Walker in the other mechine to find the missing dlls

What is the reason for that,is there any possibility for it work.

Use Dependency Walker to find out what all dll's does your application depend on. When you take your app to new location you have to have these dependent dll's there too else the application won't work.

I dont know your code also what is it?
sometimes you need to these files
mfc71d.dll msvcp71d.dll msvcr71d.dll
of course this is not always and it maybe depend to your code

Suggestion: ( May be it will work)

If your EXE is not dependent on any DLL after watching in "dependancy walker" , then i think you should build EXE in Release mode and build it using Statically Link Libraries.

Problem calling JavaScript from C++

Hello, everyone.

I'm currently working on a project for which I need to update some UI elements based on networık messages...

For the UI, for simplicity, I've chosen to use DHTML and for now most things are working as expected... Except for one: JavaScript calls!

Actually, all examples where you use a UI button for a JavaScript call work; but when a call is done without any button being pressed, there's an error!

One other project actually does a JavaScript call when window loading is complete. To simulate my problem, I downloaded the project from http://www.codeproject.com/dialog/web_gui/Reusing_DHTML_example.zip and in Dlg4.cpp changed the last method into

<br />
DWORD WINAPI CallJScriptLater( LPVOID lpParam )<br />
{<br />
    CHtmlCtrl* a = (CHtmlCtrl*) lpParam;<br />
<br />
    Sleep(5000);<br />
<br />
    CStringArray strArray;<br />
<br />
    <br />
    strArray.Add("Picture@500");<br />
    strArray.Add("Video Clip@200");<br />
    strArray.Add("Some more@50");<br />
<br />
    // first element in array <br />
    // Name @ size @ free_space<br />
    strArray.Add("File Document@1708@201");<br />
<br />
    // Call Html Script, to set parameters <br />
    a->CallJScript2("SetParameters", strArray);<br />
<br />
    return 0;<br />
}<br />
<br />
void CDlg4::_onDocumentComplete(){<br />
<br />
    CHtmlDialog::_onDocumentComplete();<br />
<br />
    CreateThread( NULL, 0, CallJScriptLater, &m_HtmlCtrl, 0, NULL);<br />
}<br />

So, instead of calling the JavaScript directly it calls it five seconds later...

When you launch it, five seconds later, you receive an error message; and the JavaScript doesn't work!

Would anyone have an explanation and / or a fix for this problem?

Thank you

Hello

I've received a reply saying that the function is probably false.

Actually, if you replace

CreateThread( NULL, 0, CallJScriptLater, &m_HtmlCtrl, 0, NULL);

with

CallJScriptLater( &m_HtmlCtrl );

It just works perfectly back again!

So, calling JavaScript from a seperate thread is impossible

Can anyone help me about this issue?

Thank you

You have to add an ON_UPDATE_COMMAND_UI handler for these menus and update these menus based on flags that holds the state for these menu items.

as nibu said, u can do ths in ON_UPDATE_COMMAND_UI function.
First get the menu bar using GetMenuBar() function.
then select the Sub menu using the required index.
Disable menu item by EnableMenuItem function by setting MF_GRAYED and MF_DISABLED flags.

hope this helps.

This won't work here. It will get overridden in the ON_UPDATE_COMMAND_UI handler. MFC does it in a different way.

You can do like this

CMainFrame::OnUpdateYourFunction(CCmdUI *pCmdUI)<br />
{<br />
	// TODO: Add your command update UI handler code here<br />
	if(A)<br />
		pCmdUI->Enable(TRUE);<br />
	else<br />
		pCmdUI->Enable(FALSE);<br />
}

possible to link and run with .lib file without .dll file?

Hello everyone,

I usually link with .lib file and when program executes, it will look for .dll file to load real function implementations.

I heard that it is possible to link with .lib file and the program can run without .dll file (.dll file needs not be generated and not needed at all during program execution). Is that correct? If it is, could anyone introduce some online tutorials about this topic?

thanks in advance,
George

CTreeCtrl: Index of and item from parent

Hi All,

Can we get index from of a child item from its parent? i.e
I have Parent1 and it has sub items Child1,Child2,Child3,Child4,Child5,

example I want to get child3's index. it is at location 2 (0 based) from it parent.

It is possible through iterating and comparing.

Is there any other way to accomplish this?

You can use GetChildItem or GetItem. GetChildItem has sample code with it in MSDN.

Try this (haven't tested it, might need to replace CTreeViewCtrl with CTreeCtrl if using MFC):

int GetChildIndex(CTreeViewCtrl* pTree, HTREEITEM hParent, HTREEITEM hFindChild)<br />
{<br />
	HTREEITEM hChild = pTree->GetChildItem(hParent);<br />
<br />
	int index = 0;<br />
<br />
	while (hChild && hChild != hFindChild)<br />
	{<br />
		hChild = pTree->GetNextSiblingItem(hChild);<br />
		index++;<br />
	}<br />
<br />
	if (hChild)<br />
		return index;<br />
	else<br />
		retun -1;<br />
}<br />

For this you will have to mount a partition of windows on to linux . Mount the partition in linux and copy data in the same manner as you do from any other storage device like FDD etc.

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