Currently I have DataGridView box, clicking generate button fills it with a query from the database.I want the add button to add another row filled using the same query, so far I cannot get it to do it.Current generate button code:
Me.TableAdapter.FillBy1(Me.DataSet.App)
Add button code:
Me.DataSet.App.Rows.Add() - this does add a new empty row
I tried sticking the generate code inside (between add brackets) it but that just did the same thing as the generate code.
I have started a little program which is linked to an access database, and it basically allows the user to input a name and a picture, with the file path stored in a text box and the picturebox getting the picture location from said text box. At the moment I am using the BindingNavigator to go between data. Everything works fine, however, whenever I press previous or next, the picturebox loads up the picture using the file location of the previous datas picture field. How can I tweak this so that when I press next or previous it loads the picture into the picturebox using the file location of the data I am going to, not coming from? [code]
Im building a program that's linked to a ms access database. the function i use to update a row... In order to save a lot of typing i inserted a for loop that uses a directcast function. i did this because i have numerous text boxes that i name tb1, tb2, tb3, tb4...etc and they each correlate with row 1, row 2, row 3, row 4...etc in the database.[code].....
I have a foxpro table <b> INVENT.DBF</b> linked in MS ACCESS. When I tried to do a search in the table from vb.net application, it is taking a long time. So I want to index the foxpro table and then use it for search.
Here is the sample code I wrote in vb.net <i> cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:database.mdb;Persist Security Info=False") cn.open() cmd = New OleDbCommand("Create INDEX itmno_idx ON INVENT(ITEM_NO) ", cn) cmd.ExecuteNonQuery()</i>
But I am getting error "Cannot execute data definition statements on linked data sources" What needs to be done to index a linked foxpro table using VB.NET.
I have a system that gathers raw data from electronic devices, uses that data to populate a set of tables and allow uses to add/edit certain data and report on it. (Kind of basic right...NOT) There are 3 applications that I've written that use the same database.
One is a client that is on 3-4 user machines which allows them to see the data that has come in and work with it. Two a Data-to-Information process program which takes the raw data, checks up certain information and puts the results into the database. Third is a data gathering app that interfaces directly with the electronic devices and about 10 times per day places the raw data into a single table in the database.
If a user is in the 'client' application the data processing application crashes all over the place: 1. Database file already in use. 2. Unrecognised Database format 3. File locked exclusively by User on PC X.
Almost always on a different line of code and once when I made it retry over and over I managed to corrupt the database and had to Compact and Repair it to fix it. If no one is using the client everything works perfectly. On each client machine is a database with linked tables to the server machine. The machine that is running the Data processing is the server and the processing is using a database in a different folder that also has linked tables.
I have gone through all the recordsets in the Data Processing application and made sure that they are only using ForwardOnly and Read Only. They edit the data only with Insert, Update or Delete queries. I'm about to do the same in the Client Application as it seems to be the one that is locking everything all the time. The client machines haven't crashed on that error at all. Does it matter which version of Access is on the client and server machines? (All the clients have Access 2003 and the server has 2007 but the Database was created in 2003). Should I just convert the Access database to SQL server and be done with it?
I have created a windows form that has a datagridview linked to a DB from a DataSet. i have draged the fields from the Data Sources navigation window to various controls on my form. all works well. then i tried building my program. my first ever build. i don't know what is wrong or what i have to do. when i try to run my exe, i have the following message. can someone help me fix this?
I have a datagridview linked to a dataTable loaded from a sql server via an adapter.I wish to sort one of the column: Filenumber.The Columns is a string. For example:
M-099 M-756 M-777 M-1000
But when i sort the columns by using Me.DataGrid.Sort(DataGrid.Columns(9), System.ComponentModel.ListSortDirection.Ascending), it turns out to be:
M-099 M-1000 M-756 M-777
I would like to know how to sort it like:
M-099 M-756 M-777 M-1000
How should i go about it? I've thought of getting rid of the M- in front and putting it into another column, but it makes filtering nuisance.Also, is it true the a custom sort via an IComparer is only applicable to things without a binding source?
My Application ( Vb.Net) is to scan Access DB forms and find out the Activx control if present and it works fine. But my problem is.In some DBs we have tables with mapping path to specific locations (Table Property->Linked Table Manager) and when we relocate these DBs then we need to change the path manually otherwise it will show a message to re-link ( Access DB message) while opening the DB. And I am facing same problem while scanning through my Tool as well and my process stops, continue only by manual intervention.
Do I capture the massage event and send some user specific message to user in the Log file or Report and continue scanning further?
I am writing a small program to update data in a SharePoint list. Now where I cannot develop or use applications for SharePoint unless I am on a SharePoint server, I thought I would cheat the system by using Access to link to SharePoint lists, and then use Visual Basic to play with the Access tables. I need additional functionality other than what VBA can provide me, so that is why I am using the VB layer.Is it possible that this is not permitted? Whenever I try to update an item in the table, I receive the message:
"cannot update '(expression)'; field not updatable"
The word 'expression' here is not a filler I added, this is the actual error.If I try to make the edit manually in the table using Access, it works fine (I haven't tried it through Access VBA yet...).
How my code works is this:I have a Dataset added to the project which connects to the Access database. I add one of the tables to the dataset and create a Class object to reference the table adapter (essentially a Data Access Layer). I can read all of the data fine, and when a change is made in SharePoint, my application sees the updates when it refreshes. But when I try to write back to the table I get the error message above.
For Each r As DataRow In TableAdapter.GetData.Select("Name LIKE '*" & FileName & "*'")
[code]....
There are other columns in the table and some of them have default null values. I only want to update these two fields, but it almost seems like this is not possible. I thought I might be somehow opening the Dataset in a Read Only mode, but I can't seem to find that option anywhere.
I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.
- VS 2008 - Sharepoint 3.0 - Access 2007 - Windows Vista (The machine I'm developing it from)
History: (Do excuse me if I don't reference different methods I've taken so far correctly, I'm still learning!) I am building some search software for a law firm that I work for in Australia. It's all coming along really well, but I seem to have hit a snag getting data out of sharepoint lists and into my project!
I first attempted to add a web reference to sharepoint and after a while was able to pull in all of the data from the lists, fantastic!(OR NOT!). The issue then was when I attempted to load it up into an array using XMLNodes, whilst it loaded up fine and I could see all the data, if there was a null value in one of the columns, it wouldn't pull that null value across, therefore, I couldn't really use the data...
I'm using VS2005.After I install an application using an .msi. Everytime this application loads it tries to find the setup and installs itself again if a file has been modified. If I delete the .msi file then the application can't even load.Is there a way to remove this link between the application and the msi?
I have a large number of MS Access databases that I'm automating to relink tables. However, there is one table that can't be relinked normally as Access says it has too many indexes. A manual work-around is to link to the view in SQL Server (2000/2008) and rename that table.Now, I want to do this programatically (I'm using DAO to relink the tables, which works nicely). I've been looking at CreateTableDef, but I don't know if this is the right way of going about it. I don't want to hardcode 260+ fields that may change (this is the main table from a 3rd party vendor, so I have no control over the fields in this table, or any normalization for that matter, but that's another topic...).Also, 98% of the tables being changed are Access 2000/2003 tables. The other 2% are Access 2007/2010.[code]
I have a notification icon that is supposed to pop a bubble whenever a webbrowser object's file title changes to a specific value. Unfortunately, it won't do what I want. When I wait, and change the title from another line (Mibbit chat, so changes title when someone speaks) it still won't show a bubble.
Here's what I have:For value As Integer = 10 To 0 Step -2
I badly wanna Serialize a Linked List into XML and deserialize it back when required. I didn't get proper results when i did google. But, I learnt through the following link that it's not possible to do so. [URL]
I have the following function that combines objects based on their gameScore attribute [code]NOTE the function is in a different class than where I have the lists I'm giving it..I had to set all the game positions blank because it saw an object with the same ID but different position as a different object. I didn't realize that even though I passed in the list ByVal the code deletes the courses on the original list somehow.First I input the origonal list expecting it not to be altered and put the output as a new list.[code]Yet somehow even the last one deletes the gamePosition attribute on listGames BUT *Doesn't* do the sum funtion for them, why is this happening it doesn't make any sense, it shouldn't touch listGames
Seems to work sometimes, but when i navigate to other pages, sometimes it works soemtimes it throws and error.Error:Value of '1000000' is not valid for 'Value'. 'Value' should be between 'minimum' and 'maximum'.In the prgressbar1 properties i have maximum set to 2000000The progress bar just zipps through, and dosent really look like its "checking: the process.

I am trying to make a form that is blank and will add in 2 comboboxes, a textbox, 2 buttons and a checkbox next to each other in a row. I want the controls to be part of an array, so that all controls on a row are associated with that array number.I am currently able to make the first row appear when the form is loaded, however when i click one of the buttons(which are used to create thenext row of controls) it comes up with an error stating that the index was outside the array bounds.
Here is the code I currently have:
Public Class frmWhere Public SQLString3 As String Public locationy As Integer
I have a search engine on my ASP.net 4.0 VB site that in which I need to link the search results with their individual pages. I understand that this can be done simply with a submit button after the search textbox but a submit button wouldn't fit next to the search bar on my page, plus it wouldn't look right.
General question on linked resources. I just want to clarify what an application does with linked resources. For explanatory purposes lets say that my resources are a bunch of images. My understanding is that linked resources are really just a reference to where that resource is on disk, whereas embedded resources are stored as part of the application.
i have a simple relationship which is shown in the link below

after doing much research i cannot find a proper way of deleting rows which are linked in all 3 tables. This is the code i am using currently
strsql = "delete * from cg_security_user_right where user_id=@field1 & right_id=@field2 " Dim objcmd As New System.Data.OleDb.OleDbCommand(strsql, acsconn) ' the oledbcommand With objcmd .Parameters.AddWithValue("@field1", TextBox1.Text)
I'm having trouble dragging a record from a linked file. The structures for the three files
Customer File: First Name Last Name Address etc
[Code]...
how do i then display all the records in the booking file, in a listbox - but to also populate the relevant details from the other files. Example: after displaying the Customer ID in the booking file, to get the first name and last name from the customer file.
There are 2 ways we can add .vb files.We can add them as a link and choose not to copy. Or we can add them and copy.The way I did it in vb.6 is equivalent with add them as link and choose not to copy.Also what's the point of copying to target folder anyway? I want the original linked file to be updated when I change the file during debuging.
