I searched yesterday on codeproject. You or, in your case, not believe me.

I search for "pop up ads", i searched for "block ads", i searched for popup ads", i searched for "block popup", etc...

Perhaps I was in a rut, and was on the wrong track as to what to search for.

Overall, I am quite successful when googling around for information, or when searching on codeproject for information on how to do something.

If you know there are several articles out here that talk on this subject, I really do not mind searching for them. Would it bother you greatly to give me a hint as to what to search on?

thanks much!

Windows NT Service won't run on 2000

I have a program that runs fine as a service under windows nt, however when I try to run this on windows 2000, I get an error message when I try to manually start the service from the service control panel. (I haven't tried to let it start automatically, since I assume the problem will continue to occur.) I get the message that the Service failed to start in a timely matter error 1053. The event log shows that the process timed out at 3000 milliseconds. Does anyone have any suggestions I haven't been able to find much regarding this?

Maybe some library used by your program is missing on the Windows 2000 machine?

Unless there is something nt vs. 2000 specific in the libraries, I don't believe this to be the case, as the program works perfectly when I run it as a "standard" application, it is only when I run this as a service that there is a problem. Also the Service Main function spawns a thread where all of the applications work is done. Which incidentally is ftp processing, if that helps at all.

Pass a socket handle between apps..

Is it possible to pass a socket handle between apps?

Yes. HANDLE is a pointer to a pointer. Do you develop the applications or just one? The reason I ask is because you have to implement a solutino to send and receive the handles.

I am developing both applications.. What functions should I look at for doing such a thing?

There are several solutions for data sharing among processes.

- Winsock
- File-Mapping
- Namepipe

I recommend file-mapping. Mapping the handle of your socket with a valid name. Search for that file-mapped on the other applications via its name.

Reading certain bits

Suppose I have an unsigned integer variable. How can I read only bits 3 to 10 off of it?

do a binary and (&&) with a bitmask

i.e.

binary 0011111111000000 = 0x3FC0 (hex)

so

nResult = nNumber && 0x3FC0;

You can then use the shift operators << or >> to shift the bits if you want to strip of trailing zeros

BOOL IsBitOn (UINT uOriginal, UINT nBit)<br />
{<br />
    uOriginal >>= nBit; // Shift right, aka divide by 2^n<br />
    uOriginal &= 1; // Just get the (now) bottom bit<br />
    return (uOriginal == 1);<br />
}

and for the concisists...

#define IsBitOn (x,n)  ((x>>n)&1)<code><br />
<br />
Or if you just want to mask out the other bits,<br />
<br />
<code>uOriginal &= 0x03fc;  // &= 0000 0011 1111 1100 in binary.

I hope that helped,

OnEnterIdle and HTMLDialog

Hi!
I have a MFC application that handle idle processing by overloading CWinApp::OnIdle ; for menus and dialogs, I handle the WM_ENTERIDLE in my MainFrame. But I use ShowHTMLDialog API to display HTML page, and then, I don't receive EnterIdle any more. Why ?
Thanks for any help
Regards

i am not sure if WM_ENTERIDLE is a standard message.
if yes, u can get if from PreTranslateMessage function.
if not (it's a fuction call actually), microsoft never offers it for the class.

Re: OnEnterIdle and HTMLDialog

Stephane Rodriguez.8-Nov-02 4:55

ShowHTMLDialog shows a modal dialog box, so by definition you can't expect your app to continue to go into idle from time to time.
There's a work around for that, you have to create a separate thread, and call ShowHTMLDialog in that thread.

typedef struct

Why does some write:
typedef struct {
foo bar;
} MyStruct;
whilst I write
struct MyStruct {
foo bar;
};

I know that it's possible to declare LPMyStruct in the first example.
And why the _TAGMYSTRUCT in some cases?

I think the fomer syntax is C-code (as opposed to C++), meant to trick some C-compilers into doing what you want.

Re: typedef struct

it is all for C.

typedef struct ABC
{
foo bar;
} MyStruct;

i.e.
MyFunction(MyStruct ms); //C needs struct as description
similar to:
MyFunction(struct ABC ms);

it can be used by both C and C++.

Error when change CString data to CString data(in Hex format)

I want to change CString data to CString data(in Hex format) and change back from CString data (in Hex format)
to CString data. So I write this below code

<br />
CString m_str = "chop][:" ;<br />
CString ivstr;<br />
StrToHexStr(m_str, ivstr); <br />

StrToHexStr function change CString data to CString data(in Hex format)which have these below detail.

<br />
void StrToHexStr(CString& strData, CString& hexstrData)<br />
{	<br />
int j;<br />
CString strtemp;<br />
<br />
hexstrData.Empty();<br />
for (j=0;j<strData.GetLength();j++){<br />
strtemp.Format("%02X",strData.GetAt(j));<br />
hexstrData+=strtemp;<br />
}<br />
}<br />

I get ivstr = "63686F705D5B3A" (from m_str = "chop][:")

Then I write program to change back from CString data (in Hex format)to CString data.

<br />
ivstr = "63686F705D5B3A"; <br />
HexStrToStr(ivstr, m_str);<br />

HexStrToStr function change CString data (in Hex format)to CString data which have these below detail.

<br />
void HexStrToStr(CString& hexstrData, CString& strData)<br />
{	<br />
int j, strlen;<br />
CString c1, c2;<br />
int temp;<br />
unsigned char ctemp;<br />
<br />
strData.Empty();<br />
<br />
for (j=0;j<hexstrData.GetLength();j+=2)<br />
{<br />
    c1= hexstrData.GetAt(j);<br />
	if ((c1 == 'A')||(c1 == 'B')||(c1 == 'C')||(c1 == 'D')||(c1 == 'E')||(c1 == 'F'))<br />
	{<br />
		ctemp = c1[0];<br />
		temp = (ctemp-55)*16;<br />
	}<br />
	else<br />
	{<br />
	temp = atoi(c1)*16;<br />
	}<br />
	c2= hexstrData.GetAt(j+1);<br />
	if ((c2 == 'A')||(c2 == 'B')||(c2 == 'C')||(c2 == 'D')||(c2 == 'E')||(c2 == 'F'))<br />
	{<br />
	ctemp = c2[0];<br />
	temp = (ctemp-55);<br />
	}<br />
	else<br />
	{<br />
	temp += atoi(c2);<br />
	}<br />
	strData += temp;<br />
}<br />
}<br />

But I do not get m_str = "chop][:"
m_str is the other string

Do you know how to solve my problem?
