Add A Row In Data Table Taking Values From 2 Text Boxes Which Are Not Bound To That Table?
Dec 26, 2010
I have a login form that consists of 2 text boxes: txtUser, txtPass. Now these are not bound to any data table & I don't what them to be bound. When a new user enters his user name & password, I want to add these on a data table that has two columns: User, Pass. Data table information: Data Source = Login.accdb, Data table = LoginTable, Connection = LoginCn. I use visual basic 2010. So how do I do this?
I have looked all over the web for a way to set up a VB 2008 combobox but what I have seen makes me shudder! I want to , as In Access VBA, set the recordsource/datasource for the combobox i.e. the list shown in the combobox, to the values of another table (currency) and then when the user selects one of these values to store it in the (already) bound field of the combobox (to another table). In Access of course there was a wizard for this sort of thing, but in VB 2008 looks like it is just lots of code.
None of the Microsoft videos I have watched, or the other posts I have seen, have given me the pieces I need to understand this process. This is the one key piece of understanding that I need to finish about 4 different programs I have started in the last 2 years. All of them key on understanding the following processes:
I am a beginner programer. I am working on a windows form in vb.net Visual Studio 2010I have several text boxes, dropdowns, radio buttons and check boxes in my windows forma.
I currently have this working already for one of my combo box's, but when i try to use the same code i get this error ''There is no row at position 6.'' . The are 2 fields in the table asset_type_id, asset_type_name', im trying to dispaly the values in a combo box for the field 'asset_type_name.
the code for ' Friend Sub RetrieveCustomerInformation2()' works but the other friend sub throws the error. Imports System.Data.SqlClient Imports System.Data Imports System Imports System.Data.OleDb
I have written some functions that I have in a module. In one of the functions I would like to update a table that is in a dataset. I would like to do this with this function and not from a form class where the table could be bound. I need to call the function from various places in the application.
I have text boxes binded to table from dataset. I make changes, i save changes.. then I open database with access, i can see changes...everything is ok... Then I open application again, changes are there, everything is ok. Then I close application and go to smoke.. when I come back and open application , the new data is gone. what's happening? This is how i save changes:
I have a DataGridView that is bound to a DataSet I created from a database table named Contacts. The Contacts table contains a field called StatusId. StatusId is a foreign key to a table called Status. The Status table contains StatusId and StatusName.
I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.
I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.
I am building a data based application using VB 2008 an SQL Express. I need to create textboxes on my form using code, (With & End With) method. I need a simple code string that will allow the app to check if the field to wich the textbox wil be databound is Nul, If so the textbox will not be created.
I got a table related to another table by orderref. I need to know what should be my SQL adapter command if I need to take some information from one table and some from another where orderref = "" or should I be making two separate SQLs?
I used to have this when I had only one table: myStr = "select * from orders where Orderref='" + txtorderref.Text + "'" Dim sqldaHistory As New SqlDataAdapter(myStr, nwindconn) sqldaHistory.Fill(myDataset, "orders")
I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?
i am trying to read from a text file and enter this into a table.The text file contains just 3 didget numbers sepearted by a line to distingues a new number.

I have found some code which i need to change to accumplish this task.Can someone direct me as to what i should be trying to change,add etc i would be very greatful. I am extremly new to all of VB,ASP and using Visual Studio 2010 so please bare with me if i ask what you may percieve as silly questions.
Let's say, I have something like a table in the WebBrowser component, it's not actually a table, because the data organized in flash, but, it's organized like a table, it has like rows and columns. You can see more in the attached file. Can I transform this text organized as table into DataGridView or some another tool that serves as table. like_a_table.JPG
I have to do an application using VB.Net .The application must be able to capture values from ms word data table and map them to ms excel sheet. For your information, i have over 6000 files ms word document, each of them contains 4 data tables using the same format .Then i have this code for read from data table 1 in document 1:
I have this code to edit the datarow of my table adapter but t doesnt update the table. I think i have a missing code that's why but i cant figured it out. by the way im using vb2008 and SQL as my database. [code]
I have 1 access database with 3 tables How do I make the combobox get data from one table and input it to another table?ex.I have a table with all my Carriers and another table with jobs that are assigned to Carriers?
Program : my game is a frogger port, you make the frog cross the road until you run out of lives. When you die, you are asked to enter your name and the name is appended to the end of file called names.txt, the final score is appended to the end of a file called scores.txt.Using the System.IO functions, i read the contents of each text file, and load the contents into two separate strings (one for names, one for scores. These two long strings are then broken down using Split() command, transferring the pieces into an array. (again 2 arrays - one for names, one for scores). The contents of both arrays are then loaded into 2 listboxes, 1 for scores, 1 for names.
Problem: i can sucessfully load the contents of both files, and display them side by side - but i want to re-arrange the scores so that they are in descending order. While doing this, i need to make sure that the player name matches up with the score - so the order of the names being displayed would have to be changed aswell. After spending many, many hours trying to do it myself i have had to give up - i'm clueless. My first issue is converting the score array into integers so that the array could be sorted, the second problem is then sorting the names so that the scores and names match up.
I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.
I added a datagridview box to my form from the tools menue. I added some columns and would like to place a save button that allows users to save the data they put in those columns. The datagridview is not bound to a database, it is only being used for design reasons and a database is not necessary. What code can I use in the button to save the changes?
My application has textboxes that are bound to DataSet fields of a SQl Server 2005 database. The columns in the database allow nulls. The column properties in the DataSet have AllowDBNull set to true. Attempting to write the un-changed data back to the database replaces the NULL values with "", and the update fails on the datetime columns with an error about being unable to convert "" to a date. It appears that the problem is that the null values from the database are being converted into empty strings when the textbox is populated.
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.
