Application That Generates A Excel File Using A Datastore Data?
Mar 10, 2009
I have an application that generates a excel file using a datastore data.It was all working fine till the user asked me that he wants choose the location and name for the new file.I tried to use the html control file field, but it works only wth a pre-existing file. Then i tried the following code :
Dim fdlg As System.Windows.Forms.OpenFileDialog = New OpenFileDialog
fdlg.Title = "Escolha a localiza��o para a grava��o do arquivo excel"
fdlg.InitialDirectory = "c:\"
fdlg.Filter = "Excel Files (*.xls)|*.xls|Excel Files (*.xlsx)|*.xlsx"
[Code]...
It seams to work, but the browse window, does not appear. After sometime i realized that it opens, but behind the bowser, and it does not work since the buttons and windows does not appear.
I am trying to write a code for excel so that it generates results in the last empty column on the sheet. below is a sample data of what is there:[code]
I am reading in data from an excel file that is only viewed inside the program. This excel file is being populated by data from multiple PLCs (7) through DDE links via RS Linx Gateway. I would like this data to be written to two different excel files and specific sheets within those so that it can be viewed later on.
My program has a form that will allow the user to view the data live, meaning they look at the first excel file from the program so that they are not able to edit the DDE links or change the file in any way. The other excel files (there will be two, one for good parts, one for bad parts) have specific sheets for each part and each tester station. For example, if the part is a ABC part, and it is a good part, and it was tester on tester station 1 then it needs to be saved to the good parts excel file, in the ABC sheet and in the good tester station 1 sheet.
If part XYZ comes along and is a bad part (fails testing) then it needs to be saved to the bad parts file, the XYZ sheet and the bad tester station 1 sheet.I might have added more detail than is needed to solve the problem but I thought I would add it anyways to help you all understand my problem a little better.
i want piece of code which generates a unique extension for my windows application and that should be opened by my application only. when i click submit button it should save all the details i have entered and should save them as a file of my application type only
i'm trying to save an excel file after I open my excel application. This is what I have so far:

When saving as an xls it works fine but when saving as a htm its a disaster Just a bunch or symbols and stuff. BUT if I go into my xls document and Save As webpage from there, it works fine!
I created an application with some Crystal Reports. I published the application and installed it on the machine which is my develop machine. This machine has Vista on it and is runnig the application 100%. When I install it on a different machine with windows XP, it runs fine until it tries to load the mybase.new. It generates a windows error with no description.
I originally posted this to the XML forum and it was suggested that I post here to see what other options might be available. The complete post is here. [URL] Wondering if someone can offer me some advice on a suitable solution for an application I'm developing. I've used xml and text files in VB.net fairly extensively for storing configuration files and the like but I'm wondering if there
I'm trying to make an application where when the user clicks a button, it generates a series of 100 random numbers between 1 and 1000, and then saves those numbers in a text file. All I could come up with is generating ONE random number, but I can't figure out how to make it 100. Here is what I have:
Needs to be a component of some sort. No additional installation needed.The datastore needs to be on the local hard drive.I am using VB.Net for a desktop app running Windows XP through 7 so it needs to callable by that environment.It needs to replicatable. If I have four copies of my app running on the network, each local copy of the datastore needs to replicate with the others. As close to real time as possible.
I got a little program that generates a random line of text from a .txt file and all is working well, at least for the most part.
On occasion I get an error message popup saying "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index."
Here's my code:
CODE:
The last bit is where the random number is generated, which I am guessing where the problem itself is, but am unsure as to how to fix it...
I have a function that is reading a sequential file and storing it into an array by using the delimiters of
The first record appears correctly however, the second element in the array has two null lines at the beginning and at the end of the record. [code]...
I have a website which has a section under maintenance with a button called create a new file - when you click on this button it does a backup and generate a filename on the same page called *.tbf - the filename changes each time you click on create a new file
I am exporting data to excel and try to save to a folder which is in my application...but the excel is saving defaultly in C:Documents but i wanted to save in E:ApllicationReports Here is my code to generate excel sheet
If ComDset.Tables(0).Rows.Count > 0 Then Try With Excel .SheetsInNewWorkbook = 1
I am using Datagridview and ListView Controls in my windows desktop application using vb.net.I want to Import data directly to Excell sheet and CSV file directly from form.
Can I Post a Windows Application that uses Excel for live data calculations? Basically from the Windows app, a user makes a menu selection and which in turn opens an excel file in memory using it for calculations. These files are put together by different groups and formatted for the Windows app to build interfaces based on each file.I also accompany an .mdf file as well. Is all this possible for customers to access and run this with Windows Azure.
I need to open an excel file from vb.net and then search it for specific data. I then need to take those data and insert them into text boxes on a form that i have created. This is all controlled by a button click. I already have some code that will open a file dialog box and let me navigate to the correct file, but I am having trouble with the search portion. I have tried the Find function but I am not sure of the proper syntax. I am using Visual Studio 2008 and Excel 2003.
I am converting several VBA projects to Windows form applications. The only problem I have is that some of the functionality of Excel is essential to the application, such as R1C1 formulas. I do not want to instantiate the Excel application or access saved worksheets. All of the data is retrieved by querying Oracle databases. 2-Dimensional arrays are not an option because the columns contain differing datatypes, and DataGridViews are too slow to work with.
I thought simply dimming a Microsoft.Office.Interop.Excel.Worksheet object would be enough, but the program kept failing and upon inspecting the object's elements in debug mode, I found that every value says this:
{"Unable to cast COM object of type 'Microsoft.Office.Interop.Excel.WorksheetClass' to interface type 'Microsoft.Office.Interop.Excel._Worksheet'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D8-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."}
I have an excel file which is auto generated by third party software..and its readonly file and its data constantly keep changing online. Now I want to use or read that data in my vb.net application whenever its changes take place in excel file automatically.
I have a text file and I want to take the data from the text file and write each line into the excel file (into the same column). How do I accomplish this? I know how to read data from a text file, but I don't know how to insert the data to a excel file..
Does anyone have a source code or tutorial link how will I able to convert and Excel File data into an XML file?Currently I have tables that compose of headers and Data from excel file and i tried to use and convert into XML using "print" code but in VBA. I want to learn it by using the VB.net code.
I currently have a bunch of numbers separated by tabs saved in a text file. Is there an easy way to copy the information from that file into .xls file and add additional information (like row and column names). I need the information to be in a report format. I am not sure the best way to go about doing this.
This should be very simple but I'm very new to Visual Studio so I can't get it to work. I want to take data from an excel (2003) file and turn it into a bunch of charts that would be viewable on a webpage that I'm trying to build in Visual Studio .Net 2005 professional.
I can't seem to use an excel file as my data source, here are the steps that I've followed:
1) created a new asp.net project
2) dragged a report viewer from the toolbox and it asks me to choose a report or "Design New Report."
3) Clicked Design New Report, and it opened up a new blank report.
4) Clicked "Add New Data Source" and got the Table Adapter Configuration Wizard.
5) Clicked new connection and it brought up the Add connection table.
6) Clicked "change" under data source and I chose Microsoft ODBC Data Source (not sure if that's right.)
7) Under "Data source specification" I chose "Excel Files"
- The first time I did this it brought up a window for me to choose an excel file so I did. Something along the way failed out but it stilled saved "ConnectionString1" as a connection to that first excel file. Now every time after I choose "Excel Files" and click "OK" the add connection window disappears and it goes back to the Table Adapter Configuration Wizard with the "ConnectionString1" as the connection string. It won't let me specify any different excel file. So I did 1-6 again and picked up at 7B
7B) Instead of using "Use user or system data source name:" I chose "Use connection string:" and clicked Build.
8) Picked the "Machine Data Source" tab and chose "Excel Files" and clicked ok
9) The "Select Workbook" window appears so I went to the file I wanted to use as my data source and click OK
10) Back on the Add Connection window I clicked test connection and it succeeded so I clicked ok.
11) It goes back to the Table Adapter Config Wiz window, but the connection string only says "Dsn=Excel Files"
12) clicked Next, then Next again, then clicked on Query Builder. The Add Table window pops up but there is nothing in there for me to choose from.I've tried a million other things, here are a few of the errors that I seem to get a lot.
[IM006][Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed [HYC00][Microsoft][ODBC Excel Driver] Optional feature not implemented [HY001][Microsoft][ODBC Excel Driver] Too many fields defined.
Does anyone have any thoughts? Is there a reference I need to add or something?
I'm creating a program and it is paramount to its functionality that it can open->read->close a Microsoft Excel (.xlsx) file.Now, I've searched the forums with the keyword "Excel" and found a lot of stuff in many programming languages, none of which were any use to me.
I should pinpoint that I'm not that good at programming as university takes all my times, but every summer (like this one) i really enjoy tackling my problems via programming.[code]...
