VS 2008 : Error - No Room Is Available To Display Rows?
Jun 22, 2010
I am using this code to have current days work show at top of list:(It's working for me so I need to continue using it)
Dim FirstJobOfDay_SP As Integer
Dim Today As String
Today = DateString
[code]....
I have changed my application. Now it has two separate datagridviews each using the code above (seperate bindingSource and GridView). One each in it's own splitcontainerpanel one above the other. My intent was to allow the user to view both at once or grab the divider and slide the panels up or down to only reveal the grid they want to view.Trouble is, when one grid it completely collapsed I get an error "No room is available to display rows".
I am getting above exception when trying to set the grid property "FirstDisplayedScrollingRowIndex".
Form1 and Form2 are MDIchild form. Form1 has a datagridview, and form2 has a command button. On click of the command button the grid gets populated and everytime I click, certain number of rows get added to the grid at the end. After populating the grid i am trying to set the scrollingindex to the first row of the last set of rows added.
When form1 is closed or open and i perform the click event, the index gets set properly without giving any exception. But when I minimize form1 and perform click event, i get exception "No room is available to display rows." is getting diaplyed.
I've run into another road block while programming my game. The problem is that when a player types North in room "Crash Site" They get the description of traveling to the next room "In Trail" as well as the description of traveling to the next room after that, "Deeper In Trail" before having to type north again. I've looked over the code several times, but can't find the problem....the conditions seem to be fine, but I'm guessing that's where the problem is..
Code: ElseIf LCase$(txtInput.Text) = "go north" And Room = "Crash Site" Then Room = "In Trail"
I am not sure if this is a bug, but I doubt it.I have an application that has multiple forms. There is about 5 ListView controls in the whole application (in different windows) and they all are in details view and have columns. But there is one that is not displaying right. When I am in design mode it looks fine, like this:
How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click 'Function declarations
I have taken this part from a previous application that works. This does not display any thing in the grid when i watch it it does show that it got 1 row but in reality it does not display it
Private Sub btn_all_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_all.Click Dim con3 As New SqlConnection("xxxx")

i have a Dataset command (DELETE FROM TABLE Where Name =@name)On my winform i have a Delete button that it deletes the rows, next i want to display the number of rows deleted to a msgbox, what i get now is 0this is my code:
Me.NetworkErrorsTableAdapter.Del(par) MsgBox(" " & Me.NetworkErrorsTableAdapter.Del(par).ToString & " records deleted ")
We were given this and for some reason I can't get this to work right. Here is the whole thing:The following code should display three rows of percent signs in the msgLabel. The first row should contain one percent sign, the second row should contain two percent signs, and the third row should contain three percent signs. However, the code is not working correctly.
Any method that can effectively get the total number of rows that is StartRows to EndRows in a database table and then get the corresponding data from that row as currently I am having difficulty in retrieving out the correct row of data to the column that I am comparing. It will always get the first row of data regardless of which row I put in the handphone number which I'm comparing to. The codes below is the one which I am currently using now to detect the maxrows in the database and also to retrieve the corresponding information.
MaxRows = ds2.Tables("CustDetail").Rows.Count MaxRows = MaxRows - 1 Dim numbers() As Integer Dim EndAt As Integer inc = 0 [Code] .....
I used a msgbox(n) to see the number of rows in the database but it displays only one where I have two rows in my database. The for loop is the one which will detect the number of maxrows and also retrieve out the corresponding details. But apparently this is not the appropriate way.
How can I count how many rows are returned by a dataset and then show the total number of rows as extbox.text and read-only so that the user can only see them but not change them?
so far I have this but it dosent return a number and says it cant find table 0:tbRecordsFound.Text = ds.Tables(0).Rows.Count
I created below, this function gets all values in each cell of excel, but i do have a problem with this because its taking minutes to display the text from each cell, is there a way that i could make a function or call a excel method or property to get all values in a worksheet and put it in a string so i could display it.. actually our main purpose is to store all data that we could get into the database for reference and search criteria.[code]...

For a project i am working on, i am taking bookings. These bookings are stored in a database alongside a users personal details. The personal details are assigned an ID according to the user who booked it. A user can book more than once with different personal details.
My problem is that i want a user to be able to edit a booking. I want a list of all the names that user booked to be listed in a combo box. This is the part i am having trouble with. i am using an access database and using sql statements to pull out the data. This is what i have tried so far:
SELECT [First Name] FROM PersonalDetails GROUP BY [First Name], UserID HAVING (UserID = ?)
If i execute this query in the query editor, it works and shows the two records currently assigned the input id. However, if i try to output this to, for example, a text box, then it remains blank. I am assuming thisis because there is more than one output, but i'm not sure.
How do I dynamically display the 'Edit' on the hyperlink field based on the values on the rows, generated from the database. the gridview automatically generates rows.
I have a table on a MYSQL database called "messages" and a column called "message". When i type something into textbox1 and click button1 i want to add a row to "messages" under the column "message" with the title and message as its value.(separated by a hyphen, dash, or other small delimiter)Then reload listbox1's contents to show the new message. so i want the final message to be something like:
I have a datagridview, and I want to get an array of rows, or rows indexes in which boolean column "Aktywny" is set to True.Obviously I can Do it using loop, but LINQ will be much faster for sure...
I'm working on a project. Part of the project needs me to capture data, for example, email address, from certain rows/columns of a datagridview and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). I am familiar with doing these in web form but windows form are different and i am not familiar with it.
I created a DataSet using the DataSources wizard. I can display the rows of each Datatable one at a time. But in this case, I needed to add a new DataTable (newDT) using the Add New Table Adapter control(?) on the toolbox. newTable is derived by JOINing three different existing tables (or, dataTable) in my DataSet designer. The query works fine and returns all the data as expected. Trouble, if I try to display the rows of the newDT on textboxes, I get a NULLREFERENCE Exception.
create a chat room? My current hosting is a linux server with mysql. I want to make a client that can connect to the database.(already done) and if the user exists, to open a chat form. I want this to be multithreaded, that way I can have up to 500 people chatting with each other at the same time, from different locations. (realistically will usually be around 50)I have found some winsock type examples, but I dont understand how I can adapt that to work with a linux server... Can anyone help give me examples? I guess I basically want an IRC.(Which I dont know how to implement.)
