DB/Reporting :: DataViewGrid Enter Key For Windows
Aug 16, 2009
I am using VS2008 using VB. I have a datagridview sourced to a dataset. There are 5 fields mapped to the datagridview, three are read only. I am using the 'RowLeave' event to do some processing.
I am using the 'CellEnter' event to 'SendKeys" a tab in the read only cells. The question is simple: how do I allow the user to enter data into one of the 'editable' cells and change the 'Enter' key into a 'Tab' key, so that the data they entered is in the cell and I tab over to the next 'editable' cell, even if it is in the next row?
I have a DataViewGrid that is populated with emp records sorted by a 'header' record listing the managers name. Currently, the user is a ble to select any row, even the manager row. I want to modify the program to prevent users from being able to select the manager record or 'header' record
I can get the collection of selected rows but I cannot find a way to determine which is the first selected row. E.g. the table has 20 rows, the user selects rows 3,4,5,6 using the mouse on the rowheaders.How can I determine that the selection starts at row 3?
I'm trying to figure out how to get a query for multiple columns in my dataviewgrid.. So far i havn't even been able to make a single column query work, when i search something in First_Name for example, it returns nothing. ive used query builer, ive written the code myself, nothing seems to work.
I added a DVG to the form. Then I clicked on the small box and selected a data source through the design screen. I chose the connection and then the sproc to get the data. This all works fine. That was added in the Load sub automatically. I will make changes to the cells by code rather than allowing the user to change the cells themselves. Then I want to click a button and save the changes to the table. Everything I have tried does not work.
when opening a form I parse all items, in this case the Masked Tex boxes.
I am in Germany, I want . to be a thousand separator and , to be a decimal separator.
txt.Mask = "999,999.00" does not work, I do not understand why. Can anybody give me a hint? txt.Mask = "999.999,00" does also not work. Public Sub config_maskedTextbox(ByVal txt As MaskedTextBox)
I am trying to search a Access Db via a TextBox1 a Button1 and a dataviewgrid.My sql statement loks like this:
Select LastName FROM Clients WHERE (LastName LIKE 'TextBox1.text')
This doesn't work I have tried '" & "' around the textbox words I've tried '& TexBox1 &'. This I tried to learn from Data over forms video-- LIKE @LastName +'%' that really didn't work. If I use = "Bla bla" it will work but the LIKE word does not. Even a point in the right direction. I've spent many many many hours on this. And what makes me mad is I've done it somhow before even with a combobox as a variable in the SELECT "var" but anywayI'm wondering now if the LIKE statement isn't used in Access? and if the % wildcard is used in Access?
I am trying to use a DataViewGrid to show certain transactions.I also have a TextBox for the user to enter the transaction ID to fill the DataViewGrid.In the Query Builder it works if I give the NABTransID in the Query but I want it to read the TextBox1.text to find the transactions.
Assuming that I have a Windows Forms textbox and want to reduce the maximum amount of characters that can be allowed in via user entry, how would I do that?
I have a database app that I wrote in VB6 a while back that uses Access as the backend. I have installed the app on Windows 7 pc's and all works fine....most of the time.On some pc's I see an issue where if I replace, rename, or even remove the DB, my app (b/c of something to do with Windows 7) still sees and reads the information from the old DB. It seems no matter what I do, I cannot "remove" the .mdb file from the system. As one can imagine, this is making it very hard to replace the outdated db with an updated version. I never experienced anything like this running the app in the XP environment.
I need designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"
1. I have a windows service type of application that first creates a database on the local SQL server (and a table). It then starts putting data into the table.
2. This works fine when running as a normal application but due to permissions, when it is run as a service, it can create a database but then fails to connect to it to create the Table. I understand that because its a LOCAL SYSTEM service, SQL might have problems but why does it let it create a database but not a table?? .
3. Is there anyway I could hard code a USER NAME for this database my application creates and then use it to get in? As it uses an exclusive database, I don't want to prompt the user for an SA account (and their sql may not be mixed mode).
Now that my application uses windows authentication to connect to the database, how will I authenticate the username and password that the user supplied? I've read about WindowsPrincipal and WindowsIdentity but still I have not found a way to do this.
I have a typed dataset with table adapters. I use this method because it makes it easier to design the layout of my DataGridView.The problem is I have added a new table to my dataset. When I go to the "Data Sources" list view, I can see the new table.However, if I add a new DataGridView to my form then attempt to bind it to my new data table, the table will not show up in the list of tables for that dataset.
I need to get a button to enter the applications subfolder and randomly select 1 file to be played in the windows media player COM which i have put in the form. I have tried creating a shuffling playlist but i cant get it to stop after one file is played (it just goes on shuffeling to another file, and i really do not want a playlist). I manage to create a batch file to be started to randomly pick a file in that folder, but when i do this the file is being played in the systems default player..
I'm developing a windows form app in visual studio 2008 express. I'm usin a sql compact 3.5 database on it through the program, several changes are made to database data, and so, i have on form1_closing event, a code to save the dataset back to database, something like:
Private Sub Form1_Closing(ByVal sender As System.Object, ByVal e As System.EventArgs) Me.Validate()
[CODE]................
But when i run my program on the debugger, the changes i mkae, don't get saved, are lost...is this a charecteristic of debugger, or is my "saving code" wrong?
I already built the program, and the data is not being saved. how to saving the data ? by the way, all changes to dataset are made something like this:
I'm using SQL 2008 Express with a multi user VB.NET Windows application. Do I have to add each user to the SQL user account? Does NT AuthoritySYSTEM work? I do not know how this works. So far I have NT AuthoritySYSTEM in the Security-Logins of the Server. But do I have to add it also in the database? In the databse Security-User, I have the following:

I have a function that allows a user to enter numeric vallues and also a period for the decimal points but I also want to allow for users to enter the minus sign to allow users to enter negative values . How would I go about it.

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?
I have a web browser project and the address bar doubles as a search bar (like google chrome). I need to detect if a user Ctrl/Alt + Clicks/Presses enter so it can specifically search or navigate. Any ideas?
