DB/Reporting :: SQL DataSet Selection Of Data

Mar 12, 2009

I'm writing an application to mimic a cash machine, I have a Form1 on which the user enters their PIN and chooses their card no. from a drop down box.The accountID is passed to Form2 and I know this is successfully seen by displaying it in a simple message box.A data adapter and dataset are used for this to the cards table.However, what I then require is within Form2 to retrieve the balance from that accountID in table Accounts, another data adapter and dataset have been created for this under Form2.I'm trying to get the balance into another variable, and I have written this as follows: [code]I would expect the result of this to be e.g. 100.00 but instead I am getting a response of "There is no row at position 0".

DB/Reporting :: Combobox - Get Data Based On The Selection

Jan 31, 2009

I have VS2005, Microsoft Access 2003

ComboA is binded to the Customerstbl and displays the CustomerNames. ComboB is Binded to the CustomerContactstbl for the selected customer above and displays all Contacts for that customer is a second cbobox.

I am having a hell of a time with this, When I select a customers name in ComboA, I want ComboB to automattically query the contacts in ComboB based on ComboA's selection. where do I create the query for getting the contacts for that customer?

In the Customer or Contacts tbl?

Is this something that would be better hard coding or is VS2005 that much improved that its ok to use these binding features?

DB/Reporting :: Use DataSet For Local Data Storage?

Mar 22, 2009

I need a simple method for a user to enter as many rows of data as they wish (probably won't exceed 50 in most cases and that's pushing it) and then store that data for retrieving the next time they want to reuse that list. I will also need to read the rows in for manipulating text in a file with those entries.

Would the best method to be to use the DataSet in VB Express 2008 and then use the DataGridView for allowing the display and entry of the data?

DB/Reporting :: The Result Of Selection Formula Must Be A Boolean

Nov 5, 2008

Below is my formula for a field in my report. All fields are of value type 'Number'. When I try to save the formula it gives me error "The result of selection formula must be a boolean." Why is this? Sometimes it does not catch it as an error, but when I actually run the rwport with real data, it shows the error again. Sigh.

DB/Reporting :: Dependent ComboBox Based On Selection In Major Category

Apr 3, 2009

I'm running into a little problem making one combo box dependent on the selection of another combo box. I'm using a access back-end to this project. I have two tables: MajorCategoryTbl and MinorCategoryTbl , MajorCategoryTbl has PK and description field, MinorCategoryTbl has a PK, MajorID (foreign key), and description field. I have two combo boxes on my form, one that displays the Major description, and one that displays the MinorCategoryTbl description, but the stored value is the PK for both. I want the selection of the minor category combobox to depend on what was selected in the major category combobox.

Jun 3, 2010

I am creating a program that will allow me to manage server EXE's for which I have the method to do so already completed. The problem comes when I want my front end to be able to use a database of different server configs stored in a dataset.

My Database has 4 columns (ServerID | ServerName | ServerPath | ServerMod)

I wish to be able to select the ServerName in a combo box (already done via Datasource/DataMember) and then load the ServerPATH and ServerMOD for that row into two variables.

DB/Reporting :: Why Can Not Update A Dataset

May 12, 2010

Today i have been checking out the concept of datasets and i like the way they work except for a minor issue i have with it.The following code should get a databasetable and put it in a dataset and return that set to the user.[code]I submit the table name and it will select it, read it and fill the dataset with it, then return it. And it does exactly that once.If i try to re-read the same datatable it just returns the exact same dataset as the first time yet i am 100000% sure that i changed it .

DB/Reporting :: Iterate Through The Datatables In A Dataset?

Oct 29, 2008

We are updating our SQL SERVER 2005 database to reflect the name of our new corporate masters and we need to change the values of the fields.

Once we do so, we will hit those fields with update queries, but right now, my group just needs a listing of the affected tables There are over 250 tables to search, is there a way to iterate through the tables?

I imagine I could search the datatables once I get them, so that part isn't a problem. I just need to know how to set up some code to peek in, record what needs to be changed, close it and move on to the next table.

I've done as much for a single table, but never a load like this.

DB/Reporting :: MDI / Shared Untyped Dataset?

Dec 30, 2008

I have an untyped DataSet: "ResultsData",which contains several tables: eg "EntryList_table".The Parent Form reads lines from a text file, parses the line, and distributes the necessary data to the corresponding data table.I then have several child forms which contain DataGridViews, each displaying the data in a unique format. All of these tables are Read only, and the DataGrid views only need to display the data attached. However, when I open the child forms, the data does not seem to update with each line read from the text file? As they are bound to the DataTables in 'ResultsData', the column headings appear correct, but will not populate the new data.I would like to have a 'Shared' DataSet that can be accessed by each child form (when activated), and will allow continuous modifications as the input lines are read.

DB/Reporting :: Saving Dataset To Sql Compact Db?

Feb 18, 2008

I have a program that I designed that scans my music folder, gets the id3 information, and then in turn inserts the results into a dataset

Here is what I have:
MusicLibrary.sdf with a table called MusicLib
MusicLibraryDataSet
MusicLibBindingSource
MusicLibTableAdapter
DataGridView

So far here is where I am, if I open the database through the visual studio ide, I manually put in a few songs just for testing purposes. When I run the program the DataGridView displays the data I entered. However I can't seem to figure out how to actually programatically add songs to the database. This is what i did so far:

I execute this command for each song scanned:MusicLibraryDataSet.MusicLib.AddMusicLibRow("FileName", "Artist", "Album", "Title", "Track") Then when done execute this command:MusicLibraryDataSet.MusicLib.AcceptChanges()

After I do that how do I then insert these items into the sql database itself so that the next time I load up my program the info is there. I have plenty of sql experience, but am used to doing all this in asp.net, i've never quite gotten all the table adapters and stuff.

DB/Reporting :: Strongly Typed Dataset

Apr 20, 2009

Firstly here's the code and i will explain my problem underneath. [code...]

Now as you can see I have a variable that holds a value member of the combo box Products which is the productID of the current product selected. Then it searchers through the products datatable and once its found the correct product or not it stores the answer in slectedproductrow. next I test to see if selected product row has found the product if it has i then see if the product has already been added to the order by seraching the the customer current order datatable if it hasn't it adds the current information to the order by using selected product row.

Now the problem i get is when i add the same product it still adds the information again as currentorderrow comes back as nothing everytime even if the product has been added before but if it was in the table which it should be it should skip that bit and just go to add the current qtys toghther.Also if i go to add a diffrent product it overwrites the the other one. So i can't store the customer order. Its like i can't store more than one row. By the way I have a datagrid and can see the product get over wrriten.

Extract A Dataset From Reporting Services?

Jul 21, 2009

We have a VB.NET (aspx) website with a login first page. Once the user has logged in and is authenticated they are taken to a single page with a Menu Bar at the top and a report viewer control underneath. When the user has logged in the report viewer is initially populated by a dynamic menu (a menu of links to other reports depending on each user's permission).

Now, on some reports that the user access from the main menu, they like to export the data. The nicely formatted reports export nicely to PDF but these same reports look awful when you export to excel. Further more what is required from the excel version is no formatting and also to include extra columns of data that are available form the dataset but not from the rendered report (for use with importing these expoerts into other systems).

Is it possible to extract the data that is generated from the dataset that renders the report?What I would like to do is obtain this data and create my own excel export option (of which I will put into the page Menu bar at the top of the screen). It is important to just grab the data that is generated because different data is available depending on the parameters the user has chosen.

Iterate Through A Dataset In Reporting Services?

May 31, 2011

I have the following code:

public sub PrettyRows()
dim ds as dataset = report.dataset1
dim GroupName as string = ""

[Code]....

The Protected Overrides Sub OnInit() is comparable to the load event in VB.NET.

I am utilizing this event to call my custom sub PrettyRows. This sub will iterate the rows in my dataset and change the first column in each row so that an entry only appears once, This is being utilized to identify what group the row belongs to. The rows are sorted by group and I only wish to display the group name once and I am removing all other references to the group name.
