Hello there, I would like to know if it´s possible to randomly pick a number based on a percentage, for example: from 1 to 5. nº % 1 10% 2 20% 3 10% 4 20% 5 40% I have 40% to pick 5 instead of the others. Is it possible to be implemented in VB2005 ?

1, 2: Try this:

SELECT amount, note FROM credit, payment WHERE customer_Id = $cust_id

To join them all, try JOIN command, I really dont remember how it would work for you.

Hello there, Im trying to come up with a statistic from a lottery data base (6 numbers for each draw) , it´s supposed to get that numbers that have been showed more times, for example how many times number '01' has been seen, '02' and so forth. Each draw is composed of n1, n2, n3, n4, n5 and n6. Hou can I get as return the statistic? Thank you

Well, it´s easy to program and does not need the whole .net framework to run with. I know it´s out of date, but it´s still reliable for simple tasks and even really old pcs can run. Thanks but... Does anyone have a clue about it?

Hello everyone, I got a really strange problem. I could make 2 computers to communicate to each other through hyperterminal, 115200,8,n,1 Hardware(CTS,RTS). Then I decide to make a VB6 program in one of those (with the same parameters). Sending data from VB6 is just fine (the hyperterminal in the other computer shows the same data), but when it receives any data the program crashes and the program manager shows 99% of the cpu is beings used by VB6 :confused::confused: Note.: There´re no infinite loops neither "OnComm" function is avaible in the algorithm. Did anyone have this problem? Or knows how to solve it? Thanks ;)

Hello guys! I´m using the Dir$() function, that returns the paths of the files that I want. I noticed that the sequence is always the same. I need a reverse function just like a navigation through image files, backward and foward. Does anyone have an idea? Thanks!

Hi Christian, I´m still using it, because our device is stable with vb6. The next step is vb.net (far future). But the current error makes my program crashes, =/ I´m using some specifics apis´s, not mine. I really dont know what´s happening. Thanks anyway

Hi, I made a program in visual basic 6 that is causing memory error running on Windows XP Embedded. The runtime error message: "This instruction at "0x7c910f29" referenced memory at 0x00000000" The memory could not be "read". Click on OK to terminate the program" [ OK ] The total disk space is 1gb, whose 500mb are used by WinXP Embedded. Does anyone know the possible cause?:confused: I´m not storing any huge string, either any huge collection, etc. Sometimes this message appears with frequency, others it just happens. :wtf: Thanks.

Hi Thomas, Thank you very much! I declared in a module Public m_Collection() As Collection And in my form: (i needed to "Set" in order to work) Private Sub Command1_Click() For i = 0 To 13 Set m_Collection(i) = New Collection m_Collection(i).Add "1234" Next i End Sub It work perfectly :) Thanks! Best Regards!!

Hi! Thank you very much for replying! Best Regards

Hello! Does anyone know if it's possible to dynamically create Collections in VB6? I wanted to dynamically create as many Collections as the user needs/wants. Just like TextBox1(0), TextBox1(1), and so on. Is it possible? Regards

Hi Dave! I could do it! I declared Public m_Cars As New Collection in the module :) Thank you!! :laugh: :cool:

Actually I'm reading from a CSV file, putting into collections (like data base). I believe that working with collections is the best way, instead of reading the CSV file everytime that the app needs to fill a listview ou delete a value. At the moment I gave up on collections, and I'm reading the csv all the time. =/ Thanks anyway :)

Hello there! I'm working with VB6 ( X| argh! I have no option) and I have a small problem, My application has 6 forms and the main form posses 7 collections. And the whole operation needs to work with those 7 collections (adding, deleting, counting and so on) in any Form. My problem is: how to make those 7 collections Public or "Global"?:confused: Ps.: I could do it in VB.Net but the current DLL's does not support .Net Framework yet. Thanks in advance. With Regards, Suguimoto

its must be huge. because it's simulating a memory in a "rom" inside a virtual processor. i needed a function "readmemh" from verilog, but it couldnt be translated to c++, so i did it manually. this mem is going to be read a lot of times and changed a lot of times. I think 8192 is fixed, as it was in Verilog. So i'm just gonna leave it like that Thanks!!

Thanks!! It's working! I used %x to display everything as Hex, and it's working perfectly. Thank you guys very much!!! code:

int main(int argc, char* argv[])
{
FILE *fp;
fp = fopen("mem.ini", "rt");
char str[32];
unsigned int mem[8192];
char * endptr;
int teste;

for(int i = 0; i<8192; i++){

fgets(str, 32, fp);

mem\[i\] = strtoul(str, &endptr, 16);

printf("%x\\n\\r", mem\[i\]); // %u   to display unsigned values
}

system("PAUSE");
return 0;
}

I changed to strtoul... and get the same result =/ also increased the size from 32 to 33, still get the same thing. very weird. But I'm still trying

I aprreciate your effort to help me :D so here is the code:

#include "stdafx.h"
#include
#include

int main(int argc, char* argv[])
{
FILE *fp;
fp = fopen("file.ini", "rt");
char str[32];
unsigned int mem[9];
char * endptr;

for(int i = 0; i<9; i++){
fgets(str, 32, fp);

mem\[i\] = strtol(str, &endptr, 16);

printf("%i\\n\\r", mem\[i\]);
}

system("PAUSE");
return 0;
}

I'm a newbie in c++ and this seems to be a little bit hard for me. my result:

0
0
2147483647
0
0
2147483647
0
2147483647
2147483647

2147483647(dec) is equal to 7FFFFFFF(hex) =/ whats happening? hehehe Regards

Hello, I got a file (.INI) and it's filled with a lot of hexa numbers:

00000000
00000000
FFFFFC24
00000000
00000000
FFFFFC2C
00000000
FFFFFC70
FFFFFC24

I must convert these strings hex to real hex number, obviously they must be unsigned. I tried a lot of ways, and got only trash :(( each line must be a row in an array, for example "unsigned int myArray[200];" this array must be filled with hexa from the string (INI File). Cuold anyone help me?? Thanks

Hi! Thanks for the reply. Actually I'm trying to make a simulation. With the current Verilog tool that I have, I can simulate, but it takes too long to simulate! In c++ it can be maybe 10x faster or 20x. The problem is... corventing the whole code into C++. I'm getting so many troubles! I really have no clue, I have fixed all the Verilator warnings, but the errors seem endless. hehehe but I cant give up, not yet :P Regards!
