In my application, there are two buttons(export & import ). Using the export button I can download an excel file, in that downloaded excel file, there are lots of blanks fields.
I need to upload the same file using import button but if I upload the same file then I can get many mandatory fields validation message because of blank fields. Instead of uploading the same file I have another excel file, in which every blank field are filled.
In the exported file, there is a unique id which is generated in the run time and I have to set the same unique id into another excel file, in which every blank field are filled same as the exported file but unique id is different. otherwise, I will get a validation message.
I want to replace the epricer quote number 8766876 to 4181981 in new import file.
Possibly duplicate of following question :
update excel cell in selenium webdriver
Possible solution from link :
InputStream inp = new FileInputStream("workbook.xls");
Workbook wb = WorkbookFactory.create(inp);
Sheet sheet = wb.getSheetAt(0);
Row row = sheet.getRow(2);
Cell cell = row.getCell(3);
if (cell == null)
cell = row.createCell(3);
cell.setCellType(Cell.CELL_TYPE_STRING);
cell.setCellValue("a test");
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
You cannot update Excel using Selenium, Selenium is a series of libraries that are used to drive a browser, they cannot interact with Excel documents.
If you want to interact with Excel documents you will need to use a library specifically designed to do that, some options are:
Apache POI
DocX4J
JExcelAPI
Im trying to find a way to convert xls files to pdf, and gembox spreadsheet is great for this. But i need to be able to make it fit to one page as you can when printing to pdf via excel.
Try specifying FitWorksheetWidthToPages and FitWorksheetHeightToPages properties.
For example like the following:
ExcelFile workbook = ExcelFile.Load("Sample.xls");
ExcelWorksheet worksheet = workbook.Worksheets.ActiveWorksheet;
worksheet.PrintOptions.FitWorksheetWidthToPages = 1;
worksheet.PrintOptions.FitWorksheetHeightToPages = 1;
workbook.Save("Sample.pdf");
I hope this helps.
I am writing an application that works with Excel files. So far I have been using Gembox spreadsheet to work with excel files. However, I discovered using Gembox spreadsheet I can save pics to excel files, but not retrieve them. Anyone can recommend how to retrieve a pic from excel file? Thank you
Here is how you can retrieve an image from an Excel file with GemBox.Spreadsheet:
ExcelFile workbook = ExcelFile.Load("Sample.xlsx");
ExcelWorksheet worksheet = workbook.Worksheets.ActiveWorksheet;
// Select Picture element.
ExcelPicture picture = worksheet.Pictures[0];
// Import to PictureBox control.
this.pictureBox1.Image = Image.FromStream(picture.PictureStream);
// Or write to file.
File.WriteAllBytes("Sample.png", picture.PictureStream.ToArray());
I am developing a vb.net winform project that takes a persons photo ID. I want to store the location of the photo in a SQL Server database.
In the project, a persons details are taken (Name, Number, Address, etc) and stored in the database. I can do that part no problem. A photo is taken of the person and stored in a folder on one of the drives on the network. There is an option to choose a photo from this folder in the project and it is added to the profile.
What is the best way to get the location of the image and how do I go about storing it in the Sql server database? I want to be able to use the location of the photo to call it to use again in another part of the project. Any help with this problem would be greatly appreciated.
In your application, your going to want to use a "OpenFileDialog" so the user can choose the file. See example below:
Dim ofd As New OpenFileDialog
ofd.Filter = "*.png|PNG|*.jpg|JPEG" 'Add other exensions you except here
ofd.Title = "Choose your folder"
'ofd.InitialDirectory = "c:\SomeFolder..." 'If you want an initial folder that is shown, otherwise it will use the last folder used by this appliaction in an OFD.
If ofd.ShowDialog = Windows.Forms.DialogResult.OK Then
'Something = ofd.FileName 'Do something with the result
End If
Then save the result of ofd.FileName in your table. This will be the full path and name of the file they selected.
I have WPF DataGrid (VS2010 C#). I copied the data from DataGrid to Clipboard and write it to an Excel file. Below is my code.
dataGrid1.SelectAllCells();
dataGrid1.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader;
ApplicationCommands.Copy.Execute(null, dataGrid1);
dataGrid1.UnselectAllCells();
string path1 = "C:\\test.xls";
string result1 = (string)Clipboard.GetData(DataFormats.CommaSeparatedValue);
Clipboard.Clear();
System.IO.StreamWriter file1 = new System.IO.StreamWriter(path1);
file1.WriteLine(result1);
file1.Close();
Everything works out OK except when I open the excel file it gives me two warning:
"The file you are trying to open
'test.xls' is in a different format
than specified by the file extension.
Verify that the file is not corrupted
and is from a trusted source before
opening the file. Do you want to open
the file now?"
"Excel has detected that 'test.xls' is
a SYLK file, but cannot load it."
But after I click through it, it still open the excel file OK and data are formated as it supposed to be. But I can't find how to get rid of the two warnings before the excel file is open.
You need to use csv as extension. Xls is the Excel file extension.
So
string path1 = "C:\\test.csv";
should work.
A problem like yours has already been described here : generating/opening CSV from console - file is in wrong format error.
Does it helps to solve yours ?
