Man, u want to encrypt data i agree, but why u r encrypting the question?
What is the issue, can u post the code snippet.

CString has a operator LPCTSTR meaning that the convertion to a const TCHAR* is automatic. You probably meant converting to an array of TCHAR, not a TCHAR, right ?

Hello everyone,
I think compiler is too strict in this case. You can see, no data member, no virtual function.
I am using Visual Studio 2008. The compiler error is simply because of Diamond pattern -- duplicate base class? Actually from logical point of view, there should be no ambiguity issue.
Any ideas?
class Base {
public:
int foo() {cout << "Base" << endl;}
};
class Derived1: public Base
{
public:
int foo() {cout << "Derived1" << endl;}
};
class Derived2: public Base
{
public:
int foo() {cout << "Derived2" << endl;}
};
class Final: public Derived1, public Derived2 {
public:
int foo() {cout << "Final" << endl;}
};
int main()
{
Final f;
Final* p = &f;
Base* pb = p;
return 0;
}
thanks in advance,
George

modify like this,
Final f;
Derived1* p = &f;
Base* pb = p;
this doesnot give error because compiler knows which compartment to return ie; Base of Derived1
In your case compiler cannot say which one you want Base of Derived1, Base of Derived2. Why do you say logically there is no ambiguity?

Hi,
I have added a string table to my DLL and added some strings to it.
Now, I am trying to access those strings using Loadstring. But string is not getting loaded. I tried to see the error using GetLastError(). It shows the following error message. "error 1814: The specified resource name cannot be found in the image file".
I am not getting where I am going wrong.
Anyone know about it? Thanks in advance.

Have u passed the appropriate Module handle to the LoadString API.
|
|
|
|
|
I have done it the following way.
CString strLoad;
bool b = strLoad.LoadString(GetModuleHandle(NULL), IDS_STRING18005, 1033);
|
|
|
|
|
Your dll won't be executing without an EXE(or any such mean), if you put GetModuleHandle(NULL) it returns the module that created the process (mostly the exe that loaded the dll), pass the path to dll or dll handle stored when the dll is loaded.

Yes, it has worked.
Thanks for the inputs. Thank you very much.

HI,
i cannot copy CString value to char.but it show error.I typecast the CString value ,but still i get errors.
Pls help me out.
char cAlarmStatus;
CString AlCond;
if(...)
AlCond = "HH";
else
AlCond = "LL";
strcpy(objAlarmData->cAlarmStatus,(LPCTSTR)AlCond);
I get error that cannot convert parameter one form char to char*.
Pls help me how to copy this CString AlCond to cAlarmStatus

char T[100] = {0};
CString S = "Hello";
strcpy(T, S.GetString());

To add with Maxwell's answer,
In your code you used 'char' and not 'char*'..
Try using as Maxwell said or you can allocate memory at runtime with the lenght of CString object and copy the string (but don't forget to release/delete the memory allocated)
Do your Duty and Don't expect the Result

What do you really need?
I mean, you cannot usually copy the whole CString content to a char variable (it can hold a single character), you need a character array or a pointer to dynamic allocated memory.
On the other hand, you probably don't need at a CString object:
const char * pszAlarmStatus;
if(...)
pszAlarmStatus = "HH";
else
pszAlarmStatus = "LL";
that's all.

dear all
how to get index of minimum of one array? the following is my code...but however the outcome is wrong after compiled...actually the error is corrNum.
fitness[10] is an 10 elements array,first i would like to calculate minimum value of fitness, and then i need to use its index of this minimum value of array,but result is wrong.anyone can help me? thanks a lot.
for (int i=0;i<10;i++)
{
double minValue = fitness[9];
if (fitness[i] <= minValue)
{
minValue = fitness[i];
for (int j=0;j<150;j++)
{
value = h[i][j] - irisIndNew[j];
if (value == 0)
corrNum = corrNum + 1;
}
}
}

Try moving the line "double minValue = fitness[9];" outside of the for (int i...) loop. It's getting assigned to fitness[9] every time through the loop.
double minValue = fitness[9];
for (int i=0;i<10;i++)
{
if (fitness[i] <= minValue)
{
minValue = fitness[i];
for (int j=0;j<150;j++)
{
value = h[i][j] - irisIndNew[j];
if (value == 0)
corrNum = corrNum + 1;
}
}
}

thanks friend.
could you help me to check the following code? why i couldn't assign value of p[gbest_Ind][][] to gbest1[gbest_Ind][][], thanks a lot
minValue = fitness[0];
for (int count = 0;count<10;count++)
{
if (fitness[count] < minValue )
{
minValue = fitness[count];
gbest_Ind = count;
}
}
for (int j = 0; j<3; j++)
for (int k = 0; k<4; k++)
{
gbest1[gbest_Ind][j][k]=p[gbest_Ind][j][k];
}

I have a graph plotted on a picture control. Now I want to click the mouse on top of the graph (CDC * GraphRegion) and get the coordinate of the picture control of the clicked point. How can I do it?
|
|
|
|
|
Handle the OnLButtonDown of the picture control. It will pass you the coordinates of the mouse when it was clicked in a CPoint object. The point will be in client coordinates of the picture control.

Using VS2005 I often find myself making incremental changes to an app then finding that it will start crashing in some weird way. In the general, the weirder that it crashes - the better - because then I know to just clean the solution and rebuild it.
Just wondering what the general rule is on the optimal frequency of "build solution," "clean solution," and "rebuild solution." ?
As for me, as the first paragraph suggests - I just use "build" repeatedly until I start getting some weird heap corruption thingie that I'm pretty sure I'm not causing, by then I know it's time to "clean solution" and build again....
But that's just me - an amateur hack who's copy of Ivor Horton was stolen in Ecuador.

Hi all,
recently, I changed from VS2005/XP to VS2008/Vista. Suddenly, my MFC application wants to contact the IP 224.0.0.22. I know that this is an IP for some multicast protocol.
This did not happen with VS2005 under XP! I do not know if this is an VS2008 issue and/or Vista issue.
Is there any way to disable this ? I do not want to scare customers using my application thinking this is a virus or trojan...
Thanks Ingo

I want to test for an invalid character in entered numeric (integer) data,
(e.g., enter "d23", instead of "123")
In the following code, the do loop loops infinitely after
an invalid entry, "d23". Seems like cin is not stopping to
accept more input the second time around.
Can anyone tell me what I'm doing wrong?
Thanks,
Tom
------------------------
#include <iostream>
using namespace std;
void main()
{
int x;
cout << "Type in an integer value: ";
cin >> x;
while (cin.fail())
{
cin.clear();
cout << "Invalid character.\n Type in an integer value: ";
cin >> x;
}
cout << x << endl;
}
|

hain wrote: cin >> x;
while (cin.fail())
What about:
while (! (cin >> x))
{
cin.clear();
while (cin.get() != '\n');
}

dear friend
why we can't use cin.get directly here? why we use while loop here? thanks
Li Zhiyuan

Thanks David, terrific, that works perfectly!
Problem is, your solution is mysterious to me...
I don't understand it.
Why doesn't the get() move the stream pointer
forward (after an error), so that by the time we
get back to cin>>x, the extraction starts after the
'\n' (i.e., nothing is extracted)?
Thanks again,
Tom
