MS ACCESS/ Save And Load Database From Main Form To Child Forms' Datagridview
Jun 10, 2010
I build my project and i got some problems. First i want to print barcode for books(toolstripmenu item). but i cant. here's the code that i found:
[code..]
second problem is printing again. i want to print my MS ACCESS .mdb from child datagridview's records.
third one i want to save and load(with dialogs) my database from main form to child forms' datagridview.and the last one is help provider. i prepare my own .htm help file, when press F1 it opens. but i dont know how to call provider to toolstripmenuitem and help provider keep my computer's path so when i call provider another computer, the programme cant find the path.
How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow() Dim OrderWindow As Orders = New Orders OrderWindow.ShowDialog() End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?
I was a vb6 user, done a few projects only with forums Now i am moving to vb.net(vb2010) and i have some trouble.Lets say we have a form(form1), a module(mod1) and a textbox on the form1.
i want to start a Sub (DoWork) in the module but in a new thread.
Dim Thread1 As System.Threading.Thread Thread1 = New Threading.Thread(AddressOf mod1.DoWork) Thread1.Start()
The DoWork sub does some stuff and when it's finished i want to change the text of a textbox1 in the main form and start another sub (DoWork2) on the main form under the main thread not the one DoWork is running under.
Plese do not refer me to another post that mighe give me a part answer, try to explain to me what i have to do and why.
I use a DataGridView to Add/Edit/Delete records from an Access database. Doing those 3 things is working just fine. When I try to update the database with the new Table data, nothing happens. I need to basically overwrite the table in the database with the data that was added, edited or deleted in the DataGridView. I opened the connection and got the table data like this
i have my main child form open. then i show the new form:
[Code]...
but when the form opens it flickers a lot. so i want move the new form behind the main form while it loads so the user does not see the flicker. once it is done loading i will set the form to topmost. how do i move the new form behind the main form?
I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.
I want to create an IMAGELIST in a main form and add to it then have it accessible within a child form. I found several MS examples on database shared access but this is NOT the concept I am after. Straight forward:
I have a MDI Parent form created with a MenuList, I also have the MDI child form created.ow do I go about using the MenuList to open the MDI child form within the parent form?
I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".
I am re-doing part of a GUI for my project, The Windows Alias Generator, and decided to switch to MDI. The child forms consists only of RichTextBox1. Here's the generate routine called when the save is clicked:
Private Sub SaveAsToolStripMenuItem_Click(ByVal sender As Object, ByVal e As EventArgs) Handles SaveAsToolStripMenuItem.Click, SaveToolStripButton.Click Dim ActiveMDI As Form = Me.ActiveMdiChild[code].....
But because I cannot define richtextbox1.text from the currently active MDI, I cannot use this routine...my question is this: How would I get RichTextBox1.text from the save option in the MDI form?
When the user run the application I would like to show the File menu->ServiceMenu form and the main menu should be allways on the background. I try the following: From the main menu load events call the ServiceMenu routin.
Private Sub ServiceMenu() Dim szt As New sztetelek Me.AddOwnedForm(szt)
[code]....
My problem the following the new ServiceMenu (szt form) show in the right position but cannot get focus. My user have to click on it to the form gets the focus however if the user click the File-ServiceMenu this forms works well and get the focus.I think the main menu get back the focus (If i press the ALT the File menu dropdown .... )
I have an MDI parent screen that loads on startup and a lot of child forms that load when opening. So as the child forms load there's a lot of flashing and it looks really ugly. Once they're loaded all I have to do is use a bring to front, maximized command and it works smoother than closing a form and opening a new one every time a different form is selected. I've tried creating a splash screen, minimizing the forms on load, etc and everything still works in order so first the splash screen then the forms load.
How would you set it up so a splash screen stays on top of all other forms for like 5 seconds while the forms load in the background without seeing them load? Right now the screen shows then when it's done it moves on to step 2 which is loading the child forms. If no splash screen, how do I make it load so you don't see all the child forms opening at once?
I have two forms. Form A and Form B. Form A has a datagrid that is populated from a SQL Database Table query. When a button is pressed Form B is launched that allows you to add a record to the database table. I need for the datagrid to be refreshed and show the newly added record when I close form B and go back to the parent.
i am having an issue populating two combo boxes on form load. The program will connect to an access database and pull data as instructed. Then as it pulls each record it puts it into the combo box.
This was working.. atleast i think it was. i dont recall it ever not working, however i wasn't looking for it.
My problem is that if when i load the MDI parent form and have it skip the selection form and the login form and load the next form in the sequence, it loads everything perfectly. However if the select form is loaded first, then the login form and then the form i need loaded, it will not populate. The only difference between the two different loads is that the login form calls a function that loads the form as a new project.form
I did this so that I can have multiple forms open at a time. I am assuming my problem is that I need to get the child forms handle then populating controls using that handle? but i think if I had to do that then I would beable to populate the comboboxes on the first form load using the login method of opening the form.
Here's my code.
vb.net Private Sub frmLine1t5_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Text = "Line " & LineNumber & " Test Form"
I want to load a child form which is a login form by default when the parent form is loaded.Right now when I click new file on the toolbar of the parent form, then only the login form is loaded but i want it be loaded by default without clicking anything.
[Code] I want like to check if a file exist on main form, if not: force open settings form. And then when the user is closing the form with exit button = check if the file exist again. If it doesn't exist, close application. It's a huge application and I need optimized on most parts. Also, the settings form is asking the closing question two times.
In the main form the user can choose to download information from a device.Since this request takes time, when "download information" is pressed I open new form in a separate thread: Private Sub RunDownload()
I have to write an application that consists of mainly one main form, but several different things I wanna display. Pretty standard I guess. So there is a menu, some controls, and the main stuff below (ranging form graphs, tables, dropdown boxes, print preview, etc). I would like to use it like one would use frames in html, design an object that is limited to a box or panel that I define. The literature I have does not give me a clear idea of how to do this (yet). The most obvious seem to be the use of MDI, open a predefined form with no borders, maximize it before showing and remove all minimize/maximize options. But that does not work so well. The form inside the MDI parent does not fit the size that is given for it when it is loaded. e.g.
[CODE]:......................
So my main question is: Is MDI the way to go here at all or are there better/easyer ways to achieve this? If MDI is the way to go, how do I sucessfully restrict a child form inside another object, without giving the user any opportunity to resize (i noticed that I have minnimize/maximize/close buttons, even if I disable them on the child forms themselves)
I am trying to get a MDI child form to load at the center of the MDI parent. I know it's a property on the form but it is not working. any suggestions?
I can save my data to access database and in the access database field I set it to date/time.But problem is when I get the value out from the database.. the format is always month/day/year hour:minutes:seconds example today: 5/2/2011 12:00:00..How to get the value into listview becoming May/2/2011 without the hour..Here's my code to get it from database ListView1.Items(i).SubItems.Add(dt.Rows(i)(14).ToString).The second problem is.When I would like to edit, how can the datetimepicker get the listview value ? [code] info: using access 2003 (.mdb) the Date of Birth field has been set into Date/Time.
When you complete various feats in my program, on a form called "User Details" there is a label with the text that says "Complete" only when you have completed a particular game. There is a save button, and a load button, all on different forms. How could I make a save and load feature? One that saves the fact you've completed certain games - and then when you press load after exiting and reentering the program, the Complete text will reappear.
I've created a windows form application in vb 2010. I've got all my forms complete and now want to add a Login screen. One the login screen, after the username/password is entered and OK is pressed, I try to open the a connection string. Obviously if the connection fails, the user has entered the incorrect credentials. If the credentials are ok, True is returned and I then open up the Main form that shows the correct items for the logged in user.
