You can only access an object if it was declared in the same scope or an enclosing scope. That's the techno babble explanation. :) What it means is that if you declare something inside a loop, you...

I think you have to do something like this because int** isn't a compatible type with void**.

int i = 123;
int *p = &i;

void pop( void **data ) {
*data = p;
}

int main() {

You have to be careful here. 'By reference' could mean two things, and only one of them is right. ;) Thef irst by reference is an actual reference in C++ and arrays are not passed by that reference...

toppings[z] = a[z] ;
If a is declared as a plain int, why are you subscripting it like an array of int? I think you should make the whole thing an array and that'll fix your problem.

void...

Yes, there is! :) What you need to do is access the controls through a dummy interface that calls Invoke on the control instead of manipulating it directly if it's not on the main thread.

Delegate...

I don't think they make sense for the date time picker. There's probably a few ways you can define them for the control, but I can't think of any that make a date time picker the better choice than a...

Did you try databinding?

DateTimePicker1.DataBindings.Add( "Value", MasterTable, "Dates" )

I don't think that'll work very well though. If you pick a date that isn't in the table, you'll...

The data source part of the connection string refers to an mdb file, not a folder path. I think it should be like this.

Dim DBSPATH As String = "C:\Documents and Settings\rgibson.FOODGROUP\My...

You write a C callable wrapper that runs the method.

#include <cstring>
#include <sstream>
#include <string>
#include <vector>

using namespace std;

class Split {

That's usually an error you get with malformed connection strings for ado.net. You mentioned access, are you trying to connect to the database at all? If you are, what does the connection string look...

What are you doing in the form_Load event or constructor?

I don't know. It looks like CreateRawDataBUFR is corrupting your object, but you didn't post the logic for CreateRawDataBUFR. Without the code I can't even guess where you went wrong.

I hope you're not surprised that intel's compiler has better optimizations because they _make_ the processors, and not because you just don't like microsoft. ;)

I'm not sure what you mean, but you can write a unit test method that runs the event handlers for each of the buttons as if you clicked on them. That automates a sequence of button clicks...

system is in stdlib.h, not stdio.h. It's not a good idea either because now you depend on an outside program that might be malicious. It's a big security no-no because you created a hole that hackers...

Doesn't printing \n do the same thing as fflush?

The window gets destroyed when the program ends. If you call getchar so that it blocks for input, the program doesn't end and the window isn't destroyed until getchar returns.

Put it somewhere else without all of the extra nesting, like C:\. Make sure that the extension is right. If this is access, it should be *.mdb, not *.mdp, I think. When it tells you it can't find the...

What message does the exception give you?

System.Xml and System.Xml.dll are the same thing in the reference picker. But that reference should have been added when you made a windows forms project...

You don't need to surround the database path in quotes inside a connection string. The key/value pairs are all delimited. It should look like this instead.

con.ConnectionString =...

That's what the link is for. :) Here's a super short program that does it.

Public Class MainForm
Inherits System.Windows.Forms.Form

Private _trayIcon As System.Windows.Forms.NotifyIcon

...

You can set the FormBorderStyle to None and that removes the border and toolbar completely. Is that what you wanted?

Add a NotifyIcon (http://www.codeproject.com/csharp/trayiconmenu01.asp) to your project that's only visible when the main form's window state is minimized.

I ran your code, Bench, but it doesn't do what gaggu82 asked for. It finds the search string even if it's embedded in another word, like "this is a string" prints "is is a string" instead of "is a...

There might be a way in the STL to do it, but I don't know. I'd write a search function that finds every occurrence of "is" and then checks to see if the first and last letters are on a word...

All of the memory for the stack is preallocated. The OS allocates it when the program starts and frees it when the program ends, but while the program is running, it's all still there. Going in and...

No, it doesn't. But you _do_ lose the only reference to the space you had, and that's called a memory leak because now it's allocated and won't be freed until the program ends. If your OS doesn't...

I don't know much about boost.pool, but unless it does all of the work for you then you will have to implement your own allocator.


If you need to override the default destructor, it's not...

You can handle memory by storing it all in one big block and passing out chunks just big enough for each node. Then freeing it turns into just one call to delete. But that doesn't call destructors...

What do you mean by making the data structure heavier? You have to free the memory and to free the memory you have to visit every node. The only heavy thing about the clean function is that it uses...

Use the Thread.Sleep() method.

System.Threading.Thread.Sleep( 100 )

You can use the ToString() method of the value and it will turn DBNull into an empty string.

T7.Text = tmp.Fields("Street").Value.ToString()

Or you can test for DBNull and just not set the text...

GUIs in C++ aren't really that easy unless you use C++.NET and then you could use C# because it's designed with .NET in mind while C++.NET is a patch job. Visual C# 2005 Express is a free compiler...

I think you'd be better off trying to separate the common stuff that both apps use into a dll and then having both apps reference the dll. What exactly do you need to do this for anyway?

What language do you need the compiler for? :)

That's the same thing I suggested except it's too specific to the problem. If this is homework then a good next project is to generalize the problem into a number of any length or to change the...

I just finished an app that lets you open a data connection and test stored procedures by using an XML config file to specify the stored procedures and corresponding parameter information. If I...

Ok, here are a few hints that you can bring together to do the program.

1: You can find the right side (least significant) digit for a number in any base by saying number % base. If the number is...

It says line 300. That's probably right where the offending catch is and you can look back up to find the matching try. I'd help, but I don't have a way of matching the error's line 300 to the line...
