Hi:

For example, you can write an Origin C function to convert Dec to Hex:

string Dec2Hex(int a)
{
	string strHexA;
	strHexA.Format("%p", a);
	strHexA.TrimLeft('0');
	return strHexA;
}

Then in Set Column Values dialog, say col(a) is Dec and you want to convert to Hex in col(b), you can set:

col(b) = Dec2Hex(col(a))$

Please read more information from Origin Programming Guide, and you can also search the function Hex2Dec in Origin C help.

Thanks

What's your Origin version? If it's not the latest Origin, please download the demo version from our website and have a try. You can contact your local distributor to update your Origin.

Thanks
Larry

Hi,

Origin7.5 does not support the usage in Set Column Value dialog yet.

We suggest you upgrade to newest Origin version 81, which contains many other improvements.

As to O75, please use the following function to call Larry's Dec2Hex function. Run "ConvertHelper(1, 2)" in script window.


void ConvertHelper(int nSourceColIndex, int nDestColIndex) // this index is 1 offset
{
	// The index offset is 0 in Origin C
	nSourceColIndex--;
	nDestColIndex--;
	
	Worksheet wks = Project.ActiveLayer();
	if( !wks || !wks.Columns(nSourceColIndex) || !wks.Columns(nDestColIndex) )
	{
		out_str("No acitve worksheet or input column is invalid");
		return;
	}
		
	Column colSource(wks, nSourceColIndex), colDest(wks, nDestColIndex);	
	Dataset dsSource(colSource), dsDest(colDest);
	vector<string> vsHex;
	for(int nn = 0; nn < dsSource.GetSize(); nn++)
	{
		string strHex = Dec2Hex(dsSource[nn]);
		vsHex.Add(strHex);
	}
	dsDest.PutStringArray(vsHex);	
}
