    Hi ...

    i have a background worker for loading and modify some excel sheets, after some hours memory usage is very very high ...
    Using 12.45.20181.0.

    Any ideas or is there anything missing ? Even when i only load and save the excel sheet there is memory usage is the same - nothing to do with Search&Replace i think

    reduced code for test:
                FarPoint.Win.Spread.FpSpread _Spreadsheet;
    string _File;

    _Spreadsheet = new FarPoint.Win.Spread.FpSpread();

    while (true)
    _File = "d:\\test.xls";

    _Spreadsheet.Sheets[0].Cells[1, 1].Value = "ABC";

    int x = 0;
    int y = 0;
    FarPoint.Win.Spread.SearchFoundFlags sff;
    sff = _Spreadsheet.Search(0, "1", false, false, false, false, true, false, false, false, 0, 0, 499, 499, ref x, ref y);
    if (x != -1 || y != -1)
    _Spreadsheet.ActiveSheet.SetValue(x, y, "Replaced Text");
    _File = "d:\\test1.xls";

    Hi Michael,

    Since the version you are using is old. We checked with Spread 14 and the issue is not present in the latest Spread. The memory stays the same and does not increase over time. We suggest you upgrade to the latest Spread.NET version.
    If you need any other assistance, please let us know.
