I developed an application with old VB form and binding the data from Oracle database into VB form. Actually, I tried to bind the data more than 35000 records in to grid. But, it takes more than half an hour and also form was hanged and there is no output. Can you please let me know the solution to fix it and bind the data without any hang in my application. What are the steps to be followed to fix it?

View 1 RepliesI am trying to export an excel file directory into an Oracle table as opposed to looping through the range and executing a lot of insert statements. I would think that there are better ways to accomplish this in .NET but I can't seem to find any other answer besides convert excel to csv & load it using Sql Loader or External Table. Does anyone know a cleaner & more efficient way that looping through the ranges creating & executing insert statements?
View 3 RepliesFirstly I've the data in csv(delimeted file) that file in exponential number and need to convert to integer( for example [3.9888e+003, 1.0093e+002] ..need to convert to 3989,1009). how to convert it in vb2008.
then send it to datagridview
I've the data in Datagridview (2 column - wavelength, absorbance) and i need to display in text box based on some reference. let say my first reference (soot it has wavelength value plus minus 2000 (range 1998 until 2002), 2nd ref NO2 plus minus 1630 (range 1628 until 1632) and others ref.
Firstly the system will find the specified wavelength in column1 (datagridview). if wavelength(column1) found in that range it will display the value in the textbox (column2- absorbance). then the information in the textbox, need to be save in oracle.
trying to write a dynamic sql query that fetches data from oracle 10g database. My Where criteria is giving me real problems but i guess it has to do with the oracle data format. The data column is a TIMESTAMP data type storing values like 25-JAN-09 07.06.01.000000000 AM. Am trying to get rows having the columns matching a specific date( ignoring the time values), my where looks like this
WHERE to_date(COMPLY_RUN_DASHBOARD_DATE,'DD-MON-RR')='" & Now.Date & "'"i get the following error :CheckError ORA-01830: date format picture ends before converting entire input string
When the program is executed, the datagridview populate data and also the textboxes(example StockNumber,Description) and when i typed words in the search textbox ,the datagridview filters the matching words.When I clicked the item in the datagridview the textboxes does not changed it didnt show the information...
what the solution for my problem..i need to display the information in the textboxes when i clicked the item in the datagridview. Private Sub txtreg_delsrch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtreg_delsrch.TextChanged

i try to bind database to combo box but having (Object reference not set to an instance of an object) error during the running.
I am using two autocomplete textboxes and both of them are binding data from the same table. What I want is when I select an item from the autocomplete drop down list of textbox1 not to have the textbox2 value set. Example :
Column1 Column2
Row1 value1 value2
Row2 value3 value3
When I select value1 for textbox1 I get automatically value2 in textbox2. I do not want that.I want when I select value1 for textbox1 , textbox2 to remain empty until I select a value for it (it maybe value3)
I am trying not to become intimidated or give up.I created a simple database and added stored procedures to read the data on a Windows form using Visual Basic in VS 2010.First I tried the Data Grid Example and all worked, I was able to view the data using a connection string to call the Stored procedure.I have stepped it up a notch by trying to bind data to form controls and I am getting this error message when I try to navigate through the data.

I am creating a Reporting program in VB 2008. The first issue that I want to correct is in VB 2008 there is a Database Explorer.

View 2 RepliesI have written a rather complex dll for processing a large volume of data (~4,000,000 records) from an Oracle database. It works well, but takes about 23 hours to run.Since I wrote the code fairly compartmentalized I realized that there are 6 routines that should be able to run concurrently, and I have a multi core processor,I decided to try my first multi-threaded implementation.
In the routine I am working on I am doing no I/O everything is in memory in variables. My data is already in dataTables and hashTables. Most of the data is defined as private in the class scope, but no conflicting updates should happen because the code segments works very distinct portions of the dataTables.The concept is simple, I have 2 routines that need to complete before launching my threads, and one routine that needs to run after all of the threads have completed. Here is what I am trying;
ProcessDXDate()
ProcessHistology()

Well for some reason when i try to add a reference so that the oracle database can connect to the VB.NET 2010 program.In other words it shouldn't highlight certain code as if the database is not connected.Here is a clear summery as best as i can say what the problem is.
1. Connection from Visual Studio 2010 to Oracle plus server
2. Adding References will not be allowed for some reason.
3. The code (See example below on what it might be) is still highlighted even when i added the references several times.
I'll show just a small snip of the code coz it's more or less the same on most of the forms if i want to either update, delete, add or amend to the database. I'll show a few screenshots so to be clearer.I've tried by even looking over the notes and followed step by step and nothing works.Since i am not registered in this module this time i can't seek help of the lecturer so don't bother telling me to go and ask my teacher I've pestered the supervisor that i'd have to present this project to and she hasn't replied to my email at all so i have no clue what else to do in the matter.
Im writing a simple VB program that connects to an oracle DB which retreives and inserts data to a table I created.[code].....
I want to be able to search through a table I have created to store all the information.Rather than just searching for one variable which would be easy to do, I want to give the user the option to filter out the search from the form.So say the user hits "Find", they would be given access to 10 comboboxes, they would select the information they want to search for (They do not have to select every box) and then click "Do Find".Then the form would display all the results of the query in the form.
