Member 9350237 wrote:
connected = new bool [bl1 + bl2 + tr + ct];
because bl1, bl2,tr,ct are pointer to arrays.
That makes no sense, the value in brackets has to be the requested length of the array. So the new array needs to be long enough to contain the combined number of elements of the other arrays.
You also need to explain how you will convert from int to bool when you copy the elements of the arrays.

Thanks for responding!.
Sorry about my poor explanation..
I think I conveyed it a wrong way. I'm still in a confusion!
Let me try to explain the scenario..
Ultimately I need to make a bool array of length 10+120+20=150.This will be combinations of zeros and ones..
Out of which first 10 and last 20 positions are filled with '0'.
120 positions are divided into 10 sets of 12 members..
out of 12 positions 10 are ones and two zeros have to be randomly placed into this 12 locations..
for exp: Following are 1st and last set of 12 positions..
{1,1,1,1,0,1,1,1,1,0,1,1,.....1,1,0,1,1,1,0,1,1,1,1,1}
I'm bit stuck implementing this bool array...
As I mentined before
int baseline1[10], int baseline2[20] are 1st 10 and last 20 positions of the bool array which is basically '0', {0}..
int training[120] is to be assigend with zeros and ones in such a way that..
int catcht[20] array of zeros to be combined with array [120] as I mentioned before..
Sorry if my explanation is vague!

OK, so you know the length of the array, so you just allocate it as normal:
int arraySize = 10+120+20;
bool* boolArray = new bool[arraySize];
memset(boolArray, 0, sizeof(bool) * arraySize);
gives you an array with all elements set to zero. You now just need to add the code to set the various other items as required.
bool* pBool = boolArray + 10; for (int i = 0; i < 10; ++i) {
pBool += 12; }

Thanks a lot!!,
I'm wondering how to set random zeros and ones to pBool pointer!
you mean
pBool = rand()%2;
Still bit confused!
As I mentioned , for each set I have 12 numbers, out of which 10 numbers 'must' be 1 and 2 0s have to be put randomly into this block of ones, so total of 12: One set should be like this
{1,1,1,1,0,1,1,0,1,1,1,1,...} and in the 2nd set there must be 10 ones and 2 zeros , but position of zero will be different.
will be great if you can help me out on this!

I would do something like:
bool* pBool = boolArray + 10; srand( (unsigned)time( NULL ) ); for (int i = 0; i < 10; ++i) {
memset(pBool, 1, sizeof(bool) * 12); int rIndex = rand() % 12; pBool[rIndex] = 0; do
{
int rIndex2 = rand() % 12; pBool[rIndex2] = 0; } while (rIndex2 == rIndex);
pBool += 12; }
I have not tested this so you need to try it a few times to make sure it produces the desired results.

Did you really think that it's necessary to dump your entire unformatted code base here and expect us to guess where you are getting this error message?
[Edit]
You have several problems going on here. You have many for statements that are simply
for (i = 0; i>cde; a couple of which appear to have no purpose.
Your nested class declaration is incomplete.
Your include statements are missing.
You are declaring functions inside other functions.
This has nothing to do with C++/CLI
probably others.

Well, thanks for bringing it to my notice.Actually when I copied it into the editor on the website, it looked fine, but after submission edges of the statements were cropped off so was the formatting
 like the one u mentioned.I am not able to submit the complete statements.

You forgot the closing brace after function BILLS::enter(). If you formatted your code properly you would be able to spot such errors quite easily.

When i try to add a Dll file into the project ,using Add Reference-->under properties .The Dll file was created VC6.
The followwing error was shown Could not add reference: ..\..\\
for one of the reasons , -Targets a higher of the.net framework
-Not a.Net assembly, -Not a registered ActiveX control
suggest how to use the dll in the project
|
|
|
|
|
The error message is telling you the reason. The DLL created in VC6 is not a .NET assembly.
If you want to use it in your project, you will have to use P/Invoke.
EDIT:
Since this is the C++/CLI forum, I forgot to mention that you can also call the DLL functions directly from C++. But there is no way to add it as a .NET reference.
The difficult we do right away...
...the impossible takes slightly longer.

Not sure exactly which part of .NET you're asking about but they are not open-sourcing the C++/CLI compiler.
