How to extract a frame from a base64 encoded gif? - base64

I converted a .gif file to base64 string, and now I want to cut this string in order to represent only one frame of the gif. How do I do this? There is some character used as frame separator? Or some resolution calculation?

tell excel to treat hex values as text

I have a large hex file i've imported into excel as a csv. So its not really a hex file, just hex strings in a csv format. I have told excel to treat the values as text and they are left justified as I would expect but when I replace all the "0x" chars with '' it changes 0x0000 to 0 (still left justified). Not a huge issue but it's still not treating it as text. The real problem is what it does with "0x18E3", it treats it as scientific notation and I get 1.80E+04 and its right justified. Its change my cell format from text to scientific.

Format to text file with predefined size for each field

I have an Excel file which I need to convert to text file. Now the thing is that for each value there is a specified field size which should be there in text file. For example:
if my Excel contains a character of size 10 with value ABCDEF, then in text file it should be as ABCDEF____ (4 spaces).
After this next value is appended in similar manner with its rest of the size is left blank.
Any kind of hint or pointer will be really helpful on how to procede with this.
Assuming your string is in A1, and its length isn't more than the 10 characters:
=A1&REPT(" ",10-LEN(A1))

How to tell if ultragrid text has been truncated

We are using infragistics ultragrid to present data to the user. if the user modifies the width of a column, I need to be able to tell if the data is truncated so that I can adjust the output properly when exporting the data into pdf. We want to truncate the data when exporting to other formats to match what the user sees after the column width adjustment.
Thanks,
Currie
Whether the text is cut off or not is done automatically when drawing the string so you would need to get the available space and the string and then determine how much of it fits into the space when drawn.
Within the CellExporting event of the UltraDocumentExporter, you can get the text and the size with the following:
Size size = e.GridRow.GetCellSizeResolved(e.GridColumn);
string text = e.GridRow.GetCellText(e.GridColumn);
You can also change the value that is being exported by setting e.ExportValue to the string that you want to put in the PDF document.
What remains to be done is to determine the amount of characters that fit into the rectangle and the following should help you with that:
