I'm writing a small software similar to the calculator in Windows, the calculator in Windows has a menu bar; in the menu bar, you can find "scientific" and "standard" mode; once you select different mode, your form will be changed, but the two forms still share the same menu bar.
I want to create the same effect of this:
1. Two forms, only one is visible at any time
2. The menu bar on the top of the two forms should be shared between these forms
I just started learning VB for 2 weeks, I'm not sure my thinking can be achieved by VB, if not
how to share and edit variables between forms? I want the user to be able to enter a value into a textbox and the program store it and then load another form and do calculations and display answers but I can't get it to work.
This is a conceptual question, so I'm not inluding code yet. I can't understand how to share a context menu strip between controls - how do I know which control the user was in when he right clicked it and made a selection?
Example: I have 3 text boxes that all use the same contextmenustrip and require the exact same functionality so no need to load new options. The user selects one of the options and an event fires something like this:
Private Sub mnuX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuX.Click
how to determine which text box is responsible for it??
I'm new to VB2008 and SQL Server. I have two forms (frmCustomer and frmDetail). The frmCustomer has a datagridview containing general data of customers, and a button to open frmDetail, which contains each customers detail information. All data modification is done on frmDetail (add, delete, and edit). Currently, both forms are binded to the dataset (same table). When the two forms are loaded, each form performs a FILL function that retrieves the data from SQL Server. In addition, all modifications done on frmDetail does not show up on frmCustomer until I perform the FILL function again on both forms. Seems like I'm maintaining 2 sets of data from the same table, and I think I'm doing more work than I have to. I'm sure there are ways to make this easier, such as bind both forms to a single dataset, so I don't have to do everything twice.
Is it possible to share subscripted variables and their data between forms? So far I can't see the variables I made public in one form, in a second form.
I've recently noticed that a solution can contain multiple projects. I'd like to know if I can create a form that exists in multiple projects, so i can edit one form (or class) instead of six, and have it published in each one of them separately? I hope that makes sense....I seek not answers, but understanding, that I may not solve, but learn. What good is a fish without the skill to catch it?
Say I have public string variable called "_Test" on Form1, how can I allow Form2 to edit/read the variable from that form? I tried putting this on Form2:
Public _Test as String = Form1._Test
But if I start Form2 without Form1 being open, it gives me an exception.
There are two forms, first form list's the employees and the second form is used to add,edit the employee record. So to pass the information between the two forms i want to use the Employee Objects.To do so, where should i declare the Employee Class?
Quite a few threads on passing data from one form to another, but I'm struggling to work out how to share data between the two - back and forth.
For example:
Class1 is a class with 10 string properties
Form1 has 10 labels ("Label1", "Label2" etc) and a [Configure] button. Form2 has 10 textboxes and a [Apply] button.
I want to load with Form1, and create an instance of Class1. Click the Configure button and load Form2, passing Class1. On Form2 I want to manually fill in the 10 textboxes and hit Apply. The Apply should update the Class1 instance and close the form.
Form1's Label controls should then be updated with the data from the Class1 instance.
I'm fine creating the forms and classes, as well as passing the class into Form2 with a custom Sub New(EmptyClass as Class1) constructor. This gets the empty class into Form2, but how can I get the populated class back to Form1?
As Form1 already exists I don't want to create a new instance with another custom Sub New(PopulatedClass as Class1)
It's also key to be able to use the Form2 multiple times, basically ending up with a Data class being displayed as part of Form1 but updated using Form2? (For example if the Class has already been created and populated with data when it's passed back to Form2 for the second time I would pre-load the Textboxes with the values already in the class).
We have an application that has a main form with a map on it. Right now the paradigm is to have forms that are displayed using menu items to display information to the user. Most of these forms are modal forms, but a couple are non-modal forms that interact with the map. For some of the forms, it really would make for a better user experience if we could dock them in the main form of the app and allow the user to see both the form and the map. For instance. We could have a list of map features in a docked window, and select one of the items on the list and have the map zoom to that feature. Or do the reverse: let the users select a map item and have a docked window that shows details of the feature. Sounds great, but I wonder about what sort of gotchas we may encounter. In particular, what if we have two windows docked at the same time? Could we get tangled up in our event code?
I recently installed WSP Builder on a machine with Visual Studio 2008 already installed.Quite expectedly, the WSP Builder sub-menu appeared (and still appears) under the Visual Studio 2008 Tools menu.Having then installed Visual Studio 2010 Professional and installed WSP Builder a second time, I can not seem to find the WSP Builder sub-menu anywhere under any of the Visual Studio 2010 menus.Can anyone throw some light on this "missing menu" problem?
A thing which i've discovered with vb2010 is that you can't share files like a form or something that way it comes at least. If you attach a form or usercontrol from a different folder it will automatically copy it into the current project folder and then save to that. How can i stop vb from doing this? It won't always be but in this case i need to share a few forms among multiple projects and it would be a royal pain to have to copy them each time manually.
just wanted to ask if it is possible to have different applications sharing the same session (i.e. database session)... i'm planning on creating a web-based application and a form-based application using asp.net for web and vb.net for forms but i need to have them share sessions since some global variables will be session based and also authentication to one application should also authenticate on the other.

I've had this problem with both VS 2010 and Visual Web Developer 2010. I want to save my projects on a network share (which I have as a mapped drive), because our network drives are backed up daily. For some reason though, VS only shows local drives when I try to save a project - all my network drives do not show up.
I am trying to list folders under a specific share example: \servernameshare I want the list to display in a listbox named folderlistBx I do not want to see file names or subfolders, just a list of folders
Private Sub ListBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBtn.Click Dim FS As New FileSystemObject
I have a program that are multiple thread. Each thread calculate some data independently. however, they will need share a hashtable which controls a hardware resource. because the resource is limited, so, it may need lock the resource for a thread, and then release it when thread is finished. and the resource can not be reused immediately, will have to wait for some time, say 5 or 10 minutes, for the device to reset.
Greetings, I'm a little bit confused about SQL Server Compact behavior.I have a small app that uses a small sdf file located on a network share.The problem is that while the app itself is working perfectly well using the connection string that points the location of the sdf file on a network drive, when I try to open the same sdf using the Server Explorer I get this error:
SQL Server Compact does not support opening database files on a network share.Obviously, if the app IS working it does indeed support network shares, then why Server Explorer cannot open it?
I copied the database file to a local drive but it's not very convenient. What might be the problem?
I've been struggling for hours now to get some working code to list the share permissions of a remote share. I've got WMI code which uses win32_share which lists the shares and path and it works great. I"m now trying to add in a routine to get the share permissions as well.
I've searched just about every site for some sample code and can only find some C# (I think) code.
i try to make a program that can share a database to other people using a upload/update system but when i try to download/upload it keeps saying mdf file in use how can i make the code so that it Uploads and overwites the file without that error.as it must be so it must upload to my server (build in)and download (also build in)the error gives file in use constandly how can i fix this issue?of that file in use problem. even when these no querry or other code running?
How can i add a menu and make it to appear on all forms within that project? I remember that 2 years ago i was able to do this with VB6 however with VB 2010 i am unable to do this currently.
Right now i added a Menu Strip on all my forms by copy-paste however i want to find a better solution so that when i add a new menu item all the menus on all forms update.
I have a MDI child form with its own menus. (TestForm)When I call the child form (Testform.show) from the parent form menu, the MDI Child form's menus are appended to the container form..Essentially, the container form steals the menu of the child form..
i have to open different forms thru menu. Whenever i am opening new from the current form should be minimized and new form should be visible and when closing the new form the old one should be viewed again. First level of menu to new form works fine but when i am using form to another form minimize works fine but i need to view in normal mode again fails to view. How can i do this?
Main.WindowState = FormWindowState.Normal [Which is not working]
i am using this code to view. To minimize i have used Me.WindowState = FormWindowState.Minimized control.
