View 1 RepliesI am working on an assignment, so need to pass the file to the instructor. I thought I remembered a way to input a placeholder character(s) that tells the computer that the path is flexible until the point where I declare the actual path.
For example: if the directory is C:documentsMyProjectinDebug on my machine, and is F:usersownerclass assignmentscis101StudentAMyProjectinDebug on the instructor's machine, can I put a "wildcard" type of character that points to the ...MyProjectinDebug file that will work on both machines in the Initial Directory property?
I want my user to only be able to open files in the initial directory that I set on OpenFileDialog. I have googled a bit and found you cannot restrict, but that was information from a few years ago and I'm not sure what version. Has this control changed at all in VS 2008?
My application is handling it okay if the user does navigate out, but it would be more concise if I could prevent him from doing so in the first place. And the fact that I have found others who wanted to do this also, makes me think it might be a nice property to have built in.
I have a datagrid view containing a customer list that if if double click on a row it brings up a customer maintenance window. Once I hit a save bottom on the second form how can I automatically update the database, refresh the grid on the initial window but remain on the same row on form1 that I double clicked on in the first place. Currently I am re-loading the datagrid on the initial form with all the data once I close the second window down.

View 2 RepliesI want to save the directory that a user chooses when they open a file with the OpenFileDialog. I currently have
FileDir=My.Computer.FileSystem.CurrentDirectory

I am developing in Visual Basic 2008 Express Edition under Vista Business SP2. I have an application with an OpenFileDialog and a SaveFileDialog.

View 6 RepliesI'm writing a forms application. I'm adding a piece that allows you to double click on a row of a datagridview control to open a new form with more details. These additional details are pulled from a database, which takes a bit of time to finish.If I run the DB query from the form's load event, the form doesn't show up until everything in the load event has completed, which can take several seconds.I want the form to show up instantly when you double click, and all of the fields to be populated once the data is ready.Is there an event I should be using other than Load?
View 6 RepliesI've never come across this before:I have a series of text boxes. The text of these boxes get set on page load. then I have a submit button that calls a sub to update the table with the new values (text) in the text box. The problem is it is keeping the original text not the text that is CURRENTLY in the textbox. Anyone come across this before? Or know how to get round it?

I have a datagridview and need to do some formatting to it. On load the row 0 column 0 cell is highlighted. I need users to click on datagridview to select a value. The issue is with the initial load highlight it looks like the first row is already selected when in fact it is now. How can this highlight be disabled? Each row of has 7 cell, the user is able to select any of the cell of a row and the corresponding row ID is selected. The issue is that only that one cell is highlighted.
I would like the entire row highlighted regardless of what cell in that row is clicked on. One of the columns is a status value. I would like to color the text based on the value. For example if the Status is opened I want the text to be red, if the status is closed the text color should be default.
I need to run an If Statement that will check a few conditions.
Basically I want to get it to check a value held in a variable "Temperature" and if the value is within "1" eaither way i.e. +-1 of the value held within the variable to then to output a text string to Label200.Text Else if the condition is not met then out put another text string to Label200.Text.
Example:
Say if Temperature value held in the variable Temperature is 8.5 the if statement checks to see if the DewPoint value is "between" +-1 of the temperature value. i.e. 7.5 to 9.5 as well as the value in Humidity is equal to or greater than 90 and Pressure is Less than or Equal to 1013.25 then the conditon is met, else the conditon is not met.
I have put some code together below in NotePad++ to see if what I am trying to do is the correct way to go about it (note I have not yet tried this code in VB.NET as I don't have it at work).
pass comment on the code and if it is wrong explain what I should do to get it to work.
Dim DewPoint as Single
Dim Temperature as Single
Dim Humidity as Single

I'm creating a Windows Console application written in VB.NET and I have a few processes that need to be called only once during the lifetime of the application. If it was an ASP.NET application, I put these in the Appliction_Start method of the Global.asax.vb file. Since there isn't a Global. asax. vb for Console applications, is there an event I could handle that allows me to call my functions before Main is called?
View 2 RepliesI'm used to Access and have just created my first form in VB in Microsoft Visual Studio. I have added four check boxes to a form and they are connected to a SQL database and working fine with one exception: When I create a new record, the initial state of the checkbox is null so it shows a green square in the box and you have to click twice to actually place a check in it even though in the properties, the three state is set to false.
When I go into DataBindings/Advanced, and set the null value to zero, it fixes the problem with starting out as a null state in a new record, but then when I create a new record it carries the checked and unchecked state from the previous record over. (If it's checked in the current record and saved and then you click on new record, the checkbox stays checked.) I can't even figure out the correct syntax for manually setting the checkboxes to a false state in the new record event to fix it.
My For... Next Loop will not work and I cannot for the life of me figure out why. I have tried to display the results in a label and a text box with multiline enabled. Doesn't seem to matter. It's probably something obvious I have been overlooking for 2 hours.

Option Strict On
Option Infer Off
