This problem should be a no-brainer for anyone that programs daily. I haven't worked in VB.NET in many many months, and all of my reference books are at home. I have to modify a program that I wrote a few years back. I need to add a new form to the project that is very similar to a form already in the project. I figured I would start with the existing form and modify it. I still need the existing form in the project, so I made a copy, renamed it to the new name, then copied it back to the folder in which my project resides. Now, I need to be able to add it to the project, but I'm having trouble figuring out how. So far, I have been able to add just the code without the form. If I try to add the form, it wants to create a new form. .
For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.
I have a bound DGV that took a bit of work to get its columns set up. I'd like to show a 1-row version of this identical DGV on a second windows form. Is there a way to programatically place a copy on the second form. I would adjust the height and position of the 1-row version, and create a new binding source on the second form so that I could filter the data.
I'm building a code editor app in VB.NET (Framework 4.0) and it opens all ".por" files into individual forms consisting of a MenuBar and TextBox (multi-line).Currently I have 20 forms (all duplicates of the first on I designed) and if there are say 4 ".por" files in a directory, the first four will open up while the others hide.
I think it would be far more efficient by coding a new form For each item in form1's ListView...but I want the next so many to be a copy of the first form I designed since I spent a good bit on it.
I want to create an application which can reset itself quickly and easily (without a function to do so). I thought one way to do this is to duplicate the form in it's original form (variables, etc) from the point it first loaded.This is how I thought it could be done:
1. Click button to restart application.
2. Form in use is duplicated by creating a new form with Dim newForm as new Form.
3. New form contains all properties of the original form at the time it was first created.
4. Original form is removed, and new form is used; thereby 'restarting' the application.
I can't find any simple way to do this without making a function which completely resets every variable and object (there's a fair number of them).
copy a form without getting Duplicate reference errors that you would have to fix.So This is what i did and i felt i should share it now that i figured it out
File > Export Template > Item Template > Select Form To Copy Then Solution Explorer > Right Click on project title > Add Item > Select Exported Template > Rename file > Add Item
I am trying to create a small form that will duplicate a users entry for them.On my form i have a text box and two CheckListBox controls and a button. The user should be able enter a value into the text box, and select multiple items from both CheckedListBoxes, when they click the submit button the details will be added to a DataGridView below.
This is an example,The user enters the value Audi A4 into the textbox.
The First Checked Lsit Box is called "Colour" and from the options the user checks 'Red' and 'Blue'.
The second Checked List Box is called "Number of Doors" and from the options the user checks '3' and '5'.
When the User clicks the submit button 4 rows will be added to the DataGridView with all the different combinations, as shown below:
Model Colour No# of Doors Audi A4 Red 3 Audi A4 Red 5 Audi A4 Blue 3 Audi A4 Blue 5
I am currently using this to populate the DataGridView:
I have this data in txt file and the data keeps changing all the time.
[code]...
I would like to read all lines and compare, if the same name and same address is found, which is in the [......], then i need to count it and show the most frequent buyer!should i read it all and put in array, and compare and put the duplicate data and count into another array?
I have a VB.NET project in Visual Studio 2008 that I created a specialized addin for. The addin prompts the user to select a database table, takes a template form class's files, copies them to another directory within the project, and renames the form class within the copied files. It then opens the new form and adds controls to it based on the fields in the database table.
The copying of the template form causes the background compiler to give 'duplicate member' errors, such as "Private Sub InitializeComponents(...) has multiple definitions with identical signatures," even though I renamed the files of the new form and the class name within them. Sometimes these errors go away before the new form is opened, but when they stick around the new form doesn't open correctly, and it throws an error instead. I implemented some code to wait until there are zero errors in the error list before trying to open the new form. This has helped sometimes, but for some reason sometimes the errors don't go away at all until the addin is closed.
How to copy the template form and rename the copy without the background compiler ever noticing duplicate members. If that's not possible, then perhaps someone has an alternative?
Here is my code that copies and renames the template form:
Private Sub CreateDataForm(ByVal tableName As String, ByVal displayName As String) ', ByVal subDataForms As IList(Of Object)) Try Dim dataFormClassName As String = "frm" & MakeValidName(displayName) Dim dataFormFileName As String = dataFormClassName & cVBSuffix
I have a solution with several projects most of which are code or control libraries. I have a main windows forms application that references and uses these libraries. What i am trying to do is create a 2nd windows application that extends the main one, but i would like to be able to deploy them as separate exe's.
When i try to add a reference to the new app referencing the main app; all seems fine until i try to run the new app i get several error msgs similar to below:
Error 1 Could not find file 'ADODB.dll' referenced by assembly 'D:Visual Studio 2005ProjectsXXXinDebugXXX.exe.manifest'. <newAppName>
i have tried adding references to all the dll's in the error messages and they are still listed when i try to run the new app. I thought of a few work arounds but they require user changes to maintain separate exe's at deployment. I would like to avoid this if possible.
I am using VS 2008 and I have a solution with multiple projects. I would like to know how to open a form in project B from a Form in project A. The solution starts with the form in project A.I have tried the following and it does not produce the expected behaviour:In Form A I have added a reference to the Project B. The following code is in a form in project A. appraisal is a form in project B.
Dim appraisalForm As New appraisalApp.appraisal appraisalForm.Show()
The above solution works to a degree. As the form is instantiated in Project A, I cannot reference any of the items in the form in Project B as I could if the Form in project B was instatiated through startup.
I have a number of projects in a solution and want to be able to access forms in all of the projects from a form in the main project. I thought of doing this to keep each segment of the solution manageble. If something goes seriously wrong in one of the projects it is easier to fix that starting from scratch with the whole solution.I have found numerous suggestions on this topic from "It cannot be done" to suggestions that do not work. The closest that I have come and still does not work is as follows:
Imports VAT_List.Form1 'This is Form1 in Project 2 Public Class Form1 ' This is Form1 in the Main Project Private Sub ListsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListsToolStripMenuItem.Click 'Imports VAT_List.Form1
How to add an existing form of old project to a new project? Which extension type files to be added to work that existing form correctly?
I actually need frmContacts.vb (because a lot of textboxes and other controls are there) which I have added. Since it doesn't show any existing controls on form, I added other following files as well.

I have a List object and I want to remove the duplicated items but leaving at least one of the duplicated items in the list;I wrote something like this however I would optimize this code for better performance, is there something faster?
Const chars As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" Dim rnd As New Random() Dim mylist As List(Of String) = Enumerable.Range(1, 100).Select(Function(i)
Im doing this project but u have a problem. im trying to make it so that when a timer in the first form(form1) ticks a progress bar in the other form goes up by 1.
I have read a lot of the prior questions/answers on this topic but it only took me so far. I have a solution to which I added 2 additional programs. These 2 added programs in essence create a PDF2TIFF converter using GS. I wish to call that form and use it as a utility from my main program. After reading other answers in the forum, I added these two programs as references in the main program and imported everything available, into the main program. I have what seems to be a correct build order set up. I want to open the form in the utility project(s) from a link on my main form. I tried a few things but the only way I could write the code without errors was to instantiate the second program then call that with a button click.
i've been working on a project. it was working fine. but now i cant make any changes to the project. when i debug the changes i made to the project are not visible. even if i add a button the button is not there when i debug. i cant change my startup form. even if i change the startup form when i debug the same form get loaded.
i have completed my application successfully and now i want to deploy it on the Customer End...How i can make an .exe file of the project that also include SQL DB ??
