Custom String Formatting

toddm123 · #1 18-Feb-2005, 14:51

Hi All,

I'm using c++.net and have a string that represents a date.

"122804"(mmddyy)

Any ideas on using DateTimeFormatInfo to take that value and make it:

"20041228" (yyyymmdd)

or if not possible:

"041228"(yymmdd)

Any help would be great.

Thanks a lot,
Todd

You'll have to split and recombine it yourself. A simple function would do it.

Cool I figured as much.

Thanks,

Hi, Todd.

I'm sorry I overlooked this thread. I meant to post an answer, but the notification message got lost in the mess called my mail account

From what I understood, you are looking for a solution based on the .NET Framework. However, this was the wrong forum to post your thread. You should have posted in the .NET Forum, and I'm sure you would have gotten a solution earlier. Walt gave you a solution based on what you required by posting here. Simply stating that you use vc.net does not imply that you are using managed code.

Please don't take this the wrong way; I'm simply explaining the answer you got.

In fact, you have the possibility to accomplish what you required by means of the DateTimeFormatInfo class. Actually, you can do it without making use of it at all.

If you would have the date in the DateTime format, I think you agree that this is pretty simple:

CPP / C++ / C Code:

using namespace System;
using namespace System::Globalization;

int _tmain()
{
	CultureInfo * pCIenUS = new CultureInfo(S"en-US", false);
	CultureInfo * pCIjaJP = new CultureInfo(S"ja-JP", false);

	DateTime myDT = DateTime(2004, 12, 28);

	Console::WriteLine(S"en-US: {0}", myDT.ToString(S"F", pCIenUS));
	Console::WriteLine(S"Jap: {0}", myDT.ToString(S"F", pCIjaJP));

	return 0;
}

So, the trick would be to transform your string into that. That's not so difficult either:

CPP / C++ / C Code:

using namespace System;
using namespace System::Globalization;

int _tmain()
{

	CultureInfo * pCIenUS = new CultureInfo(S"en-US", false);
	CultureInfo * pCIjaJP = new CultureInfo(S"ja-JP", false);

	String * date = new String("12/28/04");
	//Convert the date in the string 
	//Tell "it" the initial format is the US version
	DateTime myDT = Convert::ToDateTime(date, pCIenUS);

	//let's see what it looks like in the original
	Console::WriteLine(S"en-US: {0}", myDT.ToString(S"F", pCIenUS));
	//and now, the Japanese version
	Console::WriteLine(S"ja-JP: {0}", myDT.ToString(S"F", pCIjaJP));

	// I'm not sure why the output is so "ugly"
	//the following works well
	CultureInfo* pCIdeDE = new CultureInfo(S"de-DE", false);
	Console::WriteLine(S"de-DE: {0}", myDT.ToString(S"F", pCIdeDE));

	//If you didn't figure it out, it's  German :)
	return 0;
}

In case this was not what you required and my understanding of your post was flawed, please correct me. Also, I'm sorry if my answer arrived to late for you to make use of it.
In case you confirm that you were looking for a solution that makes use of the .NET Framework, I will move this thread to the appropriate forum.

Kind regards,
Lucian

Lucian,

I really appreciate your response. I looked at that class and ended up deciding that a simple string format would work in a lot less code. If the string dates I was getting were valid date formats then I might be tempted to go the route you mention but they're not. I'd have to do string formatting on my inputs JUST to begin to use the code you mention.

Again, I appreciate your response a lot and you've cleared up some questions I still had regarding the CultureInfo class.

Thanks again,
Todd
