asp.net - Reading data from Excel First Sheet - C# -

-

There are 2 Excel Sheets - FileA & amp; FileB

Only a sheet in the FileA contains the data & amp; No shelves hidden to make sure the name is kept Sep '.

There are 3 sheets in File B in the first one & amp; The name of 'Sheet1' is named.

To test with the file, I wrote this code and it works fine. While examining the FileA schema in the code that was encountered with FileB, I see that the 'SEP' is shown as a line. Therefore, it is written to get the name of the first letter

string firstestname = dtSchema.Rows [2] ["TABLE_NAME"]. ToString ();

But for FileB, Sheet 1 appears in the schema as the first line.

  1. Why is it different for different sheets?

  2. What should I write, so that I can always get data from the first letter with the data. 

      Private Zero GetDataFromExcel () {DataSet dsExcel = null; If (true) {OleDbCommand cmdSelect = null; OleDbDataAdapter daXls = Null; OLDBConnection xlsCSV = Faucet; Datatelle dtSchema = null; {XlsCSV} Try new OleDbConnection (ExcelFileConnString); If (xlsCSV.State == ConnectionState.Closed) {xlsCSV.Open (); } DtSchema = xlsCSV.GetOleDbSchemaTable (OleDbSchemaGuid.Tables, Taps); // Screenshots dtSchema Attached if (dtSchema.Rows.Count> 0) {string FirstSheetName = dtSchema.Rows [2] ["TABLE_NAME"]. Ostring (); CmdSelect = "Select" from new OleDbCommand ("[[+ + FirstSheetName +"], xlsCSV); DaXls = New OleDbDataAdapter (); Select DaXls.SelectCommand = cmd; DsExcel = new dataset (); DaXls.Fill (dsExcel); XlsCSV.Close (); } Int count = dsExcel.Tables [0] .Rows.Count; } Hold (Exception) {} Finally {if (xlsCSV! = Null & xlsCSV.State == ConnectionState.Open} {xlsCSV.Close (); XlsCSV.Dispose (); } If (cmdSelect! = Null) {cmdSelect.Dispose (); }}}}

     library ExcelDataReader. You can read Excel files in old format (.xls) and a new (.xlsx) and you can save.  
     With this you do not have to install any Office component and it is very easy to use. I am using it since January 2014 and I love it. You can get it or  
     If you are working with only .xlsx files and you need some more advanced, you can try the Microsoft Office Open XML SDK. This is not very easy but allows you to do anything - or almost - with Excel files.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
