Miss Nazar,
if you know the ID of the EditBox you can use following api to retieve the value

1.GetDlgItemText<br />
 2.GetDlgItemInt

or I think you are using MFC , just add the variable to
the EditBox using MFC ClassWizard>>member variable,

and When ever you need the value just Call
UpdateData(TRUE); and you variable will
fill with value present in Editbox

How do I modify values (Comments, CompanyName, FileDescription, LegalCopyright, etc) in the StringFileInfo block of an external EXE resource?

Sample code would be greatly appreciated!

I don't have sources but there is no magical api that will do this(as far as I know) you havve to open the file and write to it replacing the info you want to replace with your info.

To know what to replace you need to lear about PE headers so you can find where the info is stored and overwrite it.

That's all I know on the subject,

hei, if you manage to do this send me the source to ok?

Hi Spiritofamerica. Thanks for the heads up on PE headers. I'll have to look into it. If I manage to find a solution. I'll make it available.

Well , if you are using Visual Studio IDE,
Press F9 to set a breakpoint in the source file.

Then, Go to :

Project>>Settings>>Debug TAB

In the "Executable for debug session:" Edit box, BROWSE and select the EXE file that is going to use your dll.

THEN PRESS 'OK'

NOW RUN YOUR PROGRAM BY CLICKING THE '!' ICON OR ON THE TOOLBAR...or <ctrl+f5>. THIS WILL RUN THE EXE THAT YOU SELECTED EARLIER.
NOW IF THAT PROGRAM(EXE) MAKES USE OF AN EXPORTED FUNCTION FROM YOUR DLL, AND IF YOU HAVE SET UP YOUR BREAKPOINTS CORRECTLY, YOU CAN DEBUG YOUR DLL......

happy debugging!

E_INVALIDARG with EnvDTE::Commands::AddNamedCommand

I am always getting a return value of E_INVALIDARG when the function AddNamedCommand is called: Cry | :((

CComPtr<envdte::command> pCreatedCommand;

hr = pCommands->AddNamedCommand(m_pAddInInstance, CComBSTR(commandname), CComBSTR(commandtext), CComBSTR(tb_name), VARIANT_FALSE, IDB_LOGO, NULL, EnvDTE::vsCommandStatusSupported+EnvDTE::vsCommandStatusEnabled, &pCreatedCommand);

IDB_LOGO is a 16x16 Bitmap.

I am using Visual Studio .NET 2003 on Win XP SP2. I have looked at the documentation and at other examples but I can't find where I am going wrong.

Any ideas?

CSliderCtrl Problem

I have a slider bar that determines a position in a synchronization thread. The thread accesses tonnes of linked lists, and on-disk files. Whenever the user drags the slider bar I get exceptions because the updates to the thread are too fast. I need a way to determine when the dragging has stopped, so I can only update the thread with the final slider position.
URGENT HELP NEEDED!

I think you need to handle the notification for TB_THUMBPOSITION instead of TB_THUMBTRACK. In the interests of user friendliness, you should also handle notifications for TB_PAGEDOWN, TB_PAGEUP, etc.

I am currently using ON_WM_HSCROLL.
Can you direct me to the message handler functions for TB_THUMBPOSITION

Re: CSliderCtrl Problem

SB_THUMBPOSITION is a possible value passed in the low word of the wParam parameter of the WM_HSCROLL message. In MFC it is the nSBCode parameter of the OnHScroll handler.

Base pointer Blues!!!

Suppose i have a set up like this:

class Base 
 { 
 public: 
   int x; 
   virtual void f() 
 };
class Derv:public Base
 {
 public:
   int y;
   void f();
};

void main()
{
	Base *p;
	p=new Derv[4];

       //I WANT TO ACCESS EACH ENTRY OF THE ALLOCATED ARRAY USING POINTER OF BASE
       for(int i=0;i<4;i++)
          (p+i)->y=10;  //THIS CRASHES WHEN i>0 AS I HAVE EXPLAINED BELOW
   
        delete[]p;
}

NOW HERE IS THE PROBLEM-
I can access the first element using pointer 'p' BUT if i try to acces the second element of the array by doing p+1, MY PROGRAM CRASHES...

This is the problem:
Suppose the derived class array was allocated at 0x00000000, then p contains 0x11111111. I thought that p+1 will be 0x11111111+sizeof(Derv), BUT it is 0x11111111+sizeof(Base)

SO WHAT I WANT TO KNOW FORM YOU FRIENDS IS - HOW TO ACCESS THE ELEMENTS OF A DERIVED CLASS ARRAY USING BASE CLASS POINTER ???

thanx for ur time

Hey Avenger,

Here's a funny workaround...

DWORD dw = (DWORD) p; // move in the array using this
Base* p2 = NULL;

for(int i=0;i<4;i++)
{
p2 = (Base*) dw;
p2->y=10;
dw += sizeof(Derv); // move to the next elem
}

What do you think??

hey, looking your code, i cannot see any inheritence between your two classes.

you must tell that Derv is derived from Base (public, protected or private as you like...) :

<font color=#0000FF>class </font>Base {
  <font color=#0000FF>public</font>:
    <font color=#0000FF>int </font>x;
    <font color=#0000FF>virtual void </font>f();
};

<font color=#0000FF>class </font>Derv : public Base {
  <font color=#0000FF>public</font>:
    <font color=#0000FF>int </font>y;
    <font color=#0000FF>void </font>f();
};

avenger_sb25 wrote:

impossible, nothing can be allocated at the address 0x00000000 (and even the operating system don't !). you must test if the address returned by new is different from NULL ((void*)0x00000000) :

Base* p;
p = <font color=#0000FF>new </font>Derv[4];
<font color=#0000FF>if </font>(p != NULL) {
    <font color=#0000FF>for</font> (<font color=#0000FF>int </font>i = 0; i < 4; i++) {
        p[i]->y = 10;
    }
    <font color=#0000FF>delete</font>[] p;
}

Hi,

I'm debugging one of my mfc programms. I'm using a ON_COMMAND map thing to respond to a popup menu command...

When i´m debugging this function the debugger tells me that this is 0x00000000....
This cause a lot of trouble... And it seems that this is changing from time to time...
Sometimes it's a pointer to an array, sometimes something else...

I find this really wierd...

Sounds like you are some how calling a class member function when the class no longer exist in memory. Which is the only time this should be NULL. Why it would ever be pointing to any thing else is anouther question.
