Friends,
I am automating MS word from my MFC application. I want to perform following two tasks:

- Prevent MS-Word window from closing externally i.e i want to disallow the user to close MS word window by pressing the close button of the window OR selecting "exit" from the taksbar button, OR selexting exit from system menu OR by pressing Alt+F4 E.t.c.

- Disable the "Save As" option

Can anyone tell me whether it possible to acheve the foresaid tasks. This should be noted that because i am automating from my application, i obtained the HWND handle of MS-Word window and i am alreading using this handle to perform certain tasks which are not possible by automation.

Let ViewShowDialog is the function from where you calling te New Dialog Box

YourViewClass::ViewShowDialog()
{
CYourDlg dlgObj;
dlgObj.Var=View.Var;//pass the variable Content
dlgObj.DoModal();

}

hi jawahar,
before creating the dialog object.DoModal(), assign the values in view to dialog member variables.

Your question is not clear

Ok, you have two values representing a color

snowheavy wrote:

What do you mean ? You want your first value to be changed to the second gradually ? This makes non sense unless you 'draw' that on the screen (on a line or rectangle for example). But then, this is dependent of the technology you are using. More info about that is needed. What are you using ? GDI, OpenGL, DirectX, ... ?

sorry for my poor expression ability,I use GDI,and I want to fill a region,In
fact,I have wrote this code to test:
for (int i = 0; i < step; i++)
{
COLORREF color;
color = RGB((maxR - minR)*i/step+minR,(maxG-minG)*i/step+minG,(maxB-minB)*i/step+minB);

GetView()->dcMem.FillSolidRect(6000 * i/step+5000,-2000,6000*(i+1)/step,1000,color);
}The mapm mode I am using is MM_HIMETRIC,I found some stripes on it,
I don't know why.thanks for your reply.

He's how I'd do it:

COLORREF Voodoo(COLORREF from, COLORREF to, int n, int d)
{
    // Grab the RGB components of the "from" and "to" colours.
    BTYE fr = GetRValue(from);
    BTYE fg = GetGValue(from);
    BTYE fb = GetBValue(from);
    BTYE tr = GetRValue(to);
    BTYE tg = GetGValue(to);
    BTYE tb = GetBValue(to);
 
    // Calculate the increments.
    double ri = double(tr-fr)/d;
    double gi = double(tg-fg)/d;
    double bi = double(tb-fb)/d;
 
    // Calculate and return the final colour.
    retunr RGB(fr+n*ri, fg+n*gi, fb+n*bi);
}</code>

Where:
from - The from colour.
to - The to colour.
n - The step number.
d - The total number of steps.

NOTE: This hasn't been tested.

Firewall & Spyware Issues & Their Effect On Your Program

chasetoys24-Apr-06 21:23

I have need to open a socket to grab packets from an outside server. I have many questions about this undertaking.

The socket needs to transfer data back and forth between the client and the server.

* Is there an easy framework for this in MFC?
* Static vs. Dynamic port requests.... Should we use the same port each time we run the application? Or should we use dynamic ports?
* If we use dynamic, does that mean the Windows firewall will pop up a message saying "Hey, please verify that you want this app to access the internet?
* If we use static ports, how can we gaurantee that no other app is using the same port when we request it the first time.
* If we use static ports, how do we prevent other applications from stealing our assigned port?
* Do developers usually go to the firewall makers and try to get their applications pre-approved?
* Is there a way to be 'pre-approved' for most firewalls?

Spyware Questions (we certainly aren't spyware, we just want to make sure we're not labeled as such):
* Are there any certification programs you can go through to verify your app is not spying?
* Are these effective in terms of convincing users you're a good person?
* Same kinda question as above, is there a way to get pre approved for spyware companies and let them know who you are so they won't label you as such.
* Any other hints in terms of not being labeled this app-killing adjective?

Thanks very much in advance!

Paint Issue

Hi
I have set a Background image for my ActiveX ( ATL Composite Control) and it has some static text boxes. To make them transparent i did the painting of the static text controls ( in WM_PAINT). I.e after setting the image in OnEraseBkGnd(), i invalidated the static controls whose WM_PAINT is handled. This will TextOut the text above the BG image. But when i put this in web page, it seems that the OnEraseBkGnd() is calling frequently and thus the static control paint everytime, creating flickering of the static controls ( controls blink's).

Also when i call SetWindowText() to set new string in static control, I have to call Inavlidate() the whole control to make the new text display correctly. If i just call invalidate of static control, it overwrite the old text. Next painting of the window will solve this!!

How to solve these issues?
i have used this CP link to set background.

There is a OnCtlColor Member of CWnd, in which you can set the backmode to transparent.

I did try with WM_CTLCOLORSTATIC, i could change the bgmode & color
Not able to make it transparent. I did have to draw using WM_PAINT

M_CTLCOLOR is not fired,I think it is due to ATL non MFC

When a client using shared data from remote machine.It is very fast .But with server for same it is taking more time.

The packet transmission is 300 per share data and for server 1500 as per net stat result.

As my packet size is small i disable nagle algorithm also.but not satisfied result.So Please give some guidance.

IIUC you packaged the control into a CAB and are installing it via the <object> tag? When you release a new version, update the version numbers in the DLL's version resource, and update the version numbers in the INF file (packaged inside the CAB) to match. Then on the web page, update the version field in the codebase attribute to match. IE will do the rest.
