BasicExcel.Load --- crash!!!

I'v downloaded "BasicExcel" to hanlder my Excel operation.But it meets some problem.
Sometimes,BasicExcel.Load collapse,it seems to have some relation with the Excel file.The file size is not the reason,because I have tested that.
If that case happened,open the file,then save,and redo BasicExcel.Load ,it's OK!
Does the BasicExcel have some bugs?

BasicExcel works best with MS Excel 2003.

If problem is not resolved then :
[1]create a new Excel file in MS Excel 2003 format.
[2]copy your content in newly created file.
[3]select all the content and choose Arial as the font type.
[4]save
[5]remove read only flag(if at all applicable)
[6]run the code.

these are the steps I followed when i faced similar problem and it worked.

date comparison

Hello,

I am trying to compare 2 dates and find out which one is greater. The second date is current date.
It is not working. Below is full program code :

<br />
#include <stdio.h><br />
#include <conio.h><br />
#include <time.h><br />
<br />
void CompareDates();<br />
<br />
void main()<br />
{<br />
	CompareDates();<br />
	getch();<br />
}<br />
<br />
<br />
void CompareDates() <br />
{<br />
	int year = 2010;<br />
	int month = 12;<br />
	int day = 31;<br />
<br />
	time_t rawtime1;<br />
	time(&rawtime1);<br />
	time_t rawtime2;<br />
	time(&rawtime2);<br />
<br />
	struct tm * timeinfo1;<br />
	timeinfo1 = localtime(&rawtime1);<br />
	struct tm * timeinfo2;<br />
	timeinfo2 = localtime(&rawtime2);<br />
<br />
	timeinfo1->tm_year = year - 1900;<br />
	timeinfo1->tm_mon = month - 1;<br />
	timeinfo1->tm_mday = day;<br />
	mktime (timeinfo1); //Not sure about this. When tested makes no difference with or without this line<br />
<br />
	char buffer1 [80];<br />
	strftime (buffer1,80,"timeinfo1 : %c.",timeinfo1);<br />
	puts (buffer1);<br />
<br />
	char buffer2 [80];<br />
	strftime (buffer2,80,"timeinfo2 : %c.",timeinfo2);<br />
	puts (buffer2);<br />
<br />
	if(timeinfo1 > timeinfo2) <br />
	{<br />
		puts("more");<br />
	}<br />
	else <br />
	{<br />
		puts("less");<br />
	}<br />
}<br />

Your guidance is very much appreciated.

Since you're using only date and no time, here is something you can do.
Create strings in the format yearmonthday. eg: 20101231.
Now you can do a direct comparison using the comparison operators.

Hi Guys, I am using CDateTimeCtrl in my project.I dont know how to get Date, Month and Year Separatly.
If you Know explain me with simple code

Thanks in Advance

How about reading the documentation in MSDN and letting us know what you did not understand after seeing the member functions of this class to get the date, month and year separately?
Read GetTime function and refer the SYSTEMTIME structure.

Use the method "GetTime" and then Format the CTime-object.

Example to get the month:

CTime timeTime;
theDateTimeCtrl.GetTime(timeTime);
CString strMonth(timeTime.Format(_T("%m"));

Now the Month is in the string.

Look in the documentation of strftime to get the formatting codes.

hi,i'm currently doing a project using a software,Waspmote. I have some problems with my codings,it gave me 2 errors when i tried correcting it,

In function 'void loop()':
error: expected initializer before 'uint8_t'

In function 'void loop()':
error: a function-definition is not allowed here before '{' token

could anyone kindly help me take a look at the codings and suggest ways for me to improve on it.The code is as shown below:

int n=0;

void setup(){
// setup for Serial port over USB
USB.begin();
USB.println("USB port started...");
USB.close();

// Powering BT
BT.ON();

// Init
if(!BT.init()) USB.println("Init OK");
}
void loop()
{

// Searching for devices
if(!BT.scanNetwork()) USB.println("Scan OK");
else USB.println("Scan failed");

// Printing the devices that have been found
for(int l=0;l<BT.devices_found;l++)
{
n=0;
USB.print("---- DEVICE ");
USB.print(l,DEC);
USB.print(" ---- ");
USB.print("MAC: ");
for(int m=0;m<12;m++)
{
USB.print(BT.discovered_devices[l].mac_address[m],BYTE);
}
USB.print(" -- NAME: ");
while(BT.discovered_devices[l].name[n]!='\0')
{

delay(2000);
}

Check where you put your braces { }. It looks to me like your "printData()" function is INSIDE "loop()". Indenting your code neatly NEVER hurts and often (in cases like this) helps you see what you've written.

I didn't say remove the braces. You need to get them matching correctly, like this:

func1() {    // open 1
  ...
  ...
}            // close 1

func2() {    // open 2    
  ...
  ...
}            // close 2

What you had is more like

func1() {
  ...
  ...
  func2() {
    ...
    ...
  }

}

See how the indentation makes it easy to spot the problem?

I just pasted that code into my syntax-highlighting editor, and it tells me that the very last close brace matches the one immediately after void loop(). So void printData() is still "inside" void loop(). Again, the indenting should give you a clue - void printData() isn't in column 1 like the other functions are.
