Excel file shown on i_oi_document_viewer

Hi
I am showing generated XLS file (XML in fact) on custom container using i_oi_document_viewer.
The Excel is shown without menu, just the columns and rows.
Is that possible to show an Excel menu also.
Thank you

Hi,
seems like it is not possible. Why don´t you use some other controls ?? you find some examples in trans. DWDM.

Export to Excel - File Name WAD 7.0

Hi All,
I am using Export to Excel Functionality with WAD 7.0 to export the report to excel format.
I have used button web item, with an excel picture above it. The functionality works fine.
But while exporting the name of excel file shown is WAD 7.0 name.
ex. My WAD 7.0 name is IFIOP_C07_W700, the excel file also gets saved in this name.
I want it to be made customizable.
Can you throw some pointers.
Thanks,

Hi,
i have the same issue now where i need to populate the xport file name as report name. can you send me your solution please.

Viewing Excel Files using Tomcat - Problem with caching

Hi all,
A small part of an application I'm writing has links to Excel files for users to view/download. I'm currently using Tomcat v5 as the web/app server and have some very simple code (an example is shown below) which calls the excel file.
<%@ page contentType = "application/vnd.ms-excel" %>
<%
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
response.sendRedirect("file1.xls");
%>
This all works except but I'm having one big problem.
The xls file (file1.xls) is updated via a share on the server so each month, the xls file is overwritten with the same name but with different contents. I'm finding that when an update is made to the xls file and the user then attempts to view the new file in the browser they recieve only the old xls file. It's caching the xls file and I don't want it to. How can I fix this so that it automatically gives the user the new updated file.
The only way I've managed to get Tomcat to do this is to delete the work directory and delete the file from my IE temp folder and then restart Tomcat - this is a bit much!
Any help would be greatly appreciated.
Thanks.

I'd a problem with caching a few years back, for a servlet request which returned an SVG file.
As a workaround, I ended up putting appending "#" and a timestamp / random number after it. The browser assuming each request was new, and didn't use the cache.
Eg.
http://myserver/returnSVG.do#1234567
where 1234567 is a timestamp / random.
Not sure whether you can do this on a file based URL... but maybe worth a shot...

Owen

Hyperlinks from converted excel file are not working after pdf file is moved

I have created a pdf file from an excel file that has hyperlinks in it. The hyperlinks work fine if the files are all kept in the same exact location as the time they were created. Once the files are moved (i.e. emailed to another user) the hyperlinks no longer work. An error message pops up that the file can not be found. Is there a setting or something that I'm missing in acrobat that allows for the files to be moved, so that the hyperlinks still function properly, after creation

No settings adjustments.
The issue is that links, once made, have a specific path (as shown when you view the link's text string).
When you email the files the person who recieves the email and downloads the attachments would have to have the same layout of files/folders you have.
Without that links are "broken"
You email a zip file that, when extracted, would create the folders/files in the required layout to reflect what you have.
Be well...

How to open a specific excel file by activex & overwrite by set_cell_value.vi

I've seen the 'Write Table and Chart to XL.llb', but how can i open an existing excel file/workbook/sheet and rewrite some of the data instead of open a new worksheet everytime? It may already shown in your examples somewhere, but since I'm new to activex/property node stuff, I can't figure it out. Your help is appretiated.
Thanks
Anthony

The process is very similar. Starting with the example, open the diagram and you'll see a VI labled "Open Book" (The name of the VI is actually "Open New Workbook.vi". Right click on it and select Replace/Select a VI...
Now navigate to \\Labview 7.0\examples\comm\excelexamples.llb and select the file "Open Specific Workbook.vi". This VI has an input for specifying a filename to open.
Likewise, the example also calls a VI named "Open a New Worksheet.vi" replace that with "Open a Specific Worksheet.vi" (found in the same place).

How to lookup a value in a 2D array from an Excel file - Dasylab version 12 Pro

Hi, I am new to this forum and am looking for some advice on a worksheet I'm trying to construct. I have an Excel spreadsheet that is basically a 2D array, and I want to use Dasylab v12 Pro to be able to import a value from this array based on user selections from within the Dasylab worksheet.
Column A lists 200+ diesel engine models. I've shown 9 in my Excel attachment...one model per row (shaded in yellow), and each engine model can be run at several speeds (shaded green in columns B thru F). For an engine in a given row, combined with a chosen operating speed gives you a corresponding horsepower (blue shading).
I have this Excel sheet saved somewhere on my C:/ drive, and what I want to do is when the user starts the Dasylab worksheet he will select from a drop drown menu to choose the engine model (ie A, B, C, etc) and another drop down menu to choose the speed (ie 1470, 1760, etc). I know that I can make a drop down menu with a Coded Switch within Dasylab, however it seems only 16 choices can be made from each switch, so for my 200 engine models I will need 13 switches! I know I can assign a text description like "Engine A" to a numerical value within that coded switch. Somehow I need to take those two selections made within the Dasylab experiment, and read this Excel file (ie my database of all of these 200 diesel engine models) as a 2 dimensional array by row and column to spit out the data value (the blue numbers) back into Dasylab.
The goal is to take the engine model, speed, and the horsepower obtained from the array search and write these to an .asc file that I will create a running log of this data. So, after the test page is run 50 times it will have 50 rows of data containing these 3 parameters. There is some other test data taken from my data acquisition that goes along with this, however that's not part of my 2D array predicament.
I'm taking a guess that I need to do something with global strings & variables, and some how import them and export them with an ODBC in/out module. This is something I've just never worked with before so I am a bit lost. Obviously I can just make the user type in the engine model and speed as a startup parameter at the start of the test and save that to a variable or string, but I want to make it idiot proof so that the two selections (ie row and column) can be chosen from a pre-set list and will yield my data value. Everything else related to Dasylab I am pretty proficient with.
Thanks,
Mike

This would be the best way.
Also, with version 13 they started using Phyton to create custom modules that can be programmed in DASYLab.
We arte learning this right now and I know that you can use standard message dialogs with that as well.
I would suggest to you to download a demo of V13 and take a look at the Pyton module.
Also, usually DASYLab system intgretors like us, can provide services also on things like this including Excel programming for pre and post analisys

How can i compare two excel files with different no. of records.

Hi
I am on to a small project that involves us to compare two excel files. i am able to do it but am struck up at a point. When i compare 2 different .csv files with different no. of lines i am only able to compare upto a point till when the number of lines is same in both the files.
Eg. if source file has 8 lines and target file has 12 lines. The difference is displayed only till 8 lines and the remaining 4 lines in source lines are not shown.
Can you help me in displaying those extra 4 lines in source file. I am attaching my code snippet below..
while (((strLine = br.readLine()) != null) && ((strLine1 = br1.readLine())) != null)
                 String delims = "[;,\t,,,|]";
                String[] tokens = strLine.split(delims);
                String[] tokens1 = strLine1.split(delims);
               if (tokens.length > tokens1.length)
                for (int i = 0; i < tokens.length; i++) {
                    try {
                        if (!tokens.equals(tokens1[i])) {
System.out.println(tokens[i] + "<----->" + tokens1[i]);
out.write(sno + " \t" + lineNo1 + " \t\t" + tokens[i] + "\t\t\t\t" + tokens1[i]);
out.println();
sno++;
} catch (Exception exception)
out.write(sno + " \t" + lineNo1 + " \t\t" + tokens[i] + "\t\t\t\t" + "");
out.println();
Thanks & Regards

A CSV file is not an Excel file.
But apart from that your logic makes no sense.
If the 2 files are of different sizes the files are different by definition, so further comparison isn't needed, you're done.
If you want to compare individual records, you need to compare all records from one file with all records from the other, unless the order of records is important in which case your current system might work.
That system however is overly complicated for comparing CSV files.
As you assume a single record per line, and if one can assume those records to have identical layout (so no leading or trailing whitespace in or between columns in one file that's not in the other) comparing records is simply a matter of comparing the entire lines.

Does your Excel file has the "AutoFilter" activated?

Reading contents of uploaded excel file in web dynpro java

Hi All.
I am aware how to provide facility to upload files in web dynpro java. But my requirement is that on uploading a particular file (for eg. an excel file having 10 columns), I need to read the contents of that file and store it in a table in R/3.Can anyone suggest a way how I can read the contents of the uploaded file?
Thanks and Regards,
Saurabh.

Hi.
I am having the following requirement : I have a FileUpload UI element where user clicks Browse button, selects a file from the local system and presses a Upload button. Upon pressing Upload, the name of the selected file and the contents of the file should be shown.
In the View context, I have two value attributes: FileName of type String and FileResource of type binary.
This is the code that I have in the Upload button action handler :
public void onActionUpload(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionUpload(ServerEvent)
    IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(
             IPrivateReadExcelView.IContextElement.FILE_RESOURCE);
    IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType)attributeInfo.
             getModifiableSimpleType();
    IPrivateReadExcelView.IContextElement element = wdContext.createContextElement();
    String fname = binaryType.getFileName();
    wdComponentAPI.getMessageManager().reportSuccess("File selected - "+fname); //Statement 1
     try {
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    // Statement 2
          InputStream in = new FileInputStream(fname);
          HSSFWorkbook wb = new HSSFWorkbook(in);
          wdComponentAPI.getMessageManager().reportSuccess("Successful");    //Statement 3
          int sheetsNo = wb.getNumberOfSheets();
          for (int i=0;i<sheetsNo;i++) {
               HSSFSheet sheet = wb.getSheetAt(i);
               Iterator rowsNo = sheet.rowIterator();
               while(rowsNo.hasNext()) {
                    HSSFRow rows = (HSSFRow)rowsNo.next();
                    Iterator colsNo = rows.cellIterator();
                    while(colsNo.hasNext()) {
                         HSSFCell cell = (HSSFCell)colsNo.next();
                         wdComponentAPI.getMessageManager().reportSuccess("File uploaded" +
                              "successfully");
                         if(cell.getCellType()==1) {
                              wdComponentAPI.getMessageManager().reportSuccess("00000"+
                                   cell.getStringCellValue());
                         else if(cell.getCellType()==0) {
                              String str=""+cell.getNumericCellValue();
                              wdComponentAPI.getMessageManager().reportSuccess("11111"+str);
     catch(Exception e) { wdComponentAPI.getMessageManager().raisePendingException();
    //@@end
On pressing Upload button, name of selected file is being shown(Statement 1). I am also getting Statement 2 in the output. However I am not getting Statement 3 onwards.
Where am I going wrong? Can anyone shed some light on this?

Inputting an excel file to the java servlet program

Hi,
How can I input an excel file into the java servlet program? I am using POI HSSF programming to read the content of that excel file.I have created a form that will accept the path from the user and in the servlet program, I have called a post method to retrieve the path of the file. I am getting the path of the file as a string.Then I have to access the file to read the data. But it is not working. What should I do?.Please help me.
I have created an html file to create a form that will ask the path of the file to be loaded into the servlet program.Please give me a solution,thanks in advance. The servlet program that receives the file is shown below. It just only take the name of the file and prints if that is ok.

Store data in mysql after reading from excel files

i am trying to make o program where i will read the data from excel files and i will store them in a database. I am using eclipse as editor and mySQL. I am using APACHE POI to read the excel files and JDBC for the connection. The excel files have the structure as shown below:
ID NAME SALARY STREET
321 TIM 1254 14 avenue
121 PAUL 1265 28h oktovriou
432 NICK 4521 papaflessa
I have of course plenty of such files which contains many more rows and columns. The purpose of my program is to read the data, create table named as the name of the excel file and the fields of each table to be the first rows of the excel file. Afterwards the values will be the rest data of the excel file. In the code below i have managed to read them, show the data in the console. Afterwrds i am trying to call a database with JDBC but there i have problem when i create the table.
try
String[] allFields;
String createTableStr = "CREATE TABLE" + createTableStr
+ "(" + org.apache.commons.lang3.StringUtils.join(allFields,
",") + ")";
Could anyone help me?
Thank you in advance!:)

How to continuous data acquisition and save to an excel file using vc++

Hi,
I’m trying to build an MFC application with MSVC++6, where I would continuously acquire
samples from 2 channels of a USB-6289. I’m using the DAQmx C functions. I use the following codes to continuously get data:
DAQmxErrChk(DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0,Dev1/ai1","",DAQmx_Val_Cfg_Default,-10.0,10.0,DAQmx_Val_Volts,NULL));
DAQmxErrChk(DAQmxReadAnalogF64(taskHandle,1000,-1,DAQmx_Val_GroupByChannel,data,2000,&read,NULL));
        DAQmxErrChk
(DAQmxRegisterEveryNSamplesEvent(taskHandle,DAQmx_Val_Acquired_Into_Buffer,1000,0,EveryNCallback,NULL));
        DAQmxErrChk (DAQmxRegisterDoneEvent(taskHandle,0,DoneCallback,NULL));
static int32 EveryNCallback(TaskHandle taskHandle, int32 everyNsamplesEventType, uInt32 nSamples, void *callbackData)
   int32       error=0;
   char    errBuff[2048]={'\0'};
   static int totalRead=0;
   int32       read=0;
   float64     data[1000];
   // DAQmx Read Code
   DAQmxErrChk(DAQmxReadAnalogF64(taskHandle,1000,-1,DAQmx_Val_GroupByChannel,data,2000,&read,NULL));
   if( read>0 ) {
   fflush(stdout);
       Error:
   if( DAQmxFailed(error) ) {
       DAQmxGetExtendedErrorInfo(errBuff,2048);
       DAQmxStopTask(taskHandle);
       DAQmxClearTask(taskHandle);
           return 0;
static int32 CVICALLBACK DoneCallback(TaskHandle taskHandle, int32 status, void *callbackData)
   int32   error=0;
   char    errBuff[2048]={'\0'};
   // Check to see if an error stopped the task.
   DAQmxErrChk (status);
Error:
   if( DAQmxFailed(error) ) {
       DAQmxGetExtendedErrorInfo(errBuff,2048);
           //MessageBox("errors in DoneCallBack");
       DAQmxClearTask(taskHandle);
       //MessageBox(errBuff);
   return 0;
I have two questions:
1. how to save the data into an excel file? Can anyone show me some sample codes please?
2.Are
the data acquired from the two channels simultaneously? If I set the
starting time at 0, sample frequency 1khz, can I directly multiply the
sample number by 0.001 to calculate time (as shown below)?
Time    channel1 channel2
0.001    d11           d21
0.002    d12           d22
Thank you!

Save content of picture control as .jpg into excel file?

Is it possible to save the contents shown of a picture control as a jpeg file into an excel file along with other data? Is this possible without using ActiveX? If I have to use ActiveX how do I use this?
Thanks

Hello AndyBE,
ActiveX is definitely going to be your best bet. I�ve attached an example that should meet your needs. Let me know if this works for you.
Have a nice day!
