Below is the code that is adding a toolstripmenuitem at runtime. I do need to check elsewhere to see if it exists. What I have below is incorrect. How would I change the conditional check below?
ToolStripMenuItemFile.DropDownItems.Add("Save")
ToolStripMenuItemFile.DropDownItems(2).Click += New EventHandler(SaveFile_Click)
If ToolStripMenuItemFile.DropDownItems(2) IsNot Nothing Then
ToolStripMenuItemFile.DropDownItems(2).Text = rm.GetString("Save")
End If
I'm using the coding below to determin if a certain file exists on the hdd. However there is an error on this line: If FileExists("C:myfile.txt"))="False" then msgbox "False"
it gives me the following error message:End of statement expected.
I have a function in VS2008 VB.NET that creates a dataset and reads field values from that were loaded from a SQL Server 2008 database tables. The tables are from varied sources and in some cases particular column/field names are different. Some use a long name; others use a short name. I need to determine whether a short name or a long name is being used.Pseudo code:If row("ShortName") Exists then ReadDataFrom r("ShortName").ToStringElse ReadDataFrom r("LongName").ToStringEnd If
How would I determine if a particular column name exist in a dataset or datarow?
I wanted to create a login system that would have 3 tabs 1 for regular login, 1 for admin login and 1 for account creation. So far so good. It saves the accounts by saving them in a .urs file in the map called /Users/. However when this map does not exist it will show a error. I would want to know what code or so to put into the form_load which will make my program create the map /Users/ if it does not exist. As im not familiar with all the codes and stuff. The only thing i can come up with is
Mkdir "/Users/"
but then ofcourse it would create the folder users everytime i start the program. not i was still "Hello Worlding" a few days ago, so i really am unfamiliar with any sort of high-skilled programming which i probably dont understand.
I would like to check if a URL exists -- without requesting the file. The program needs to check if a PDF or Excel spreadsheet exists at a particular URL. If it does, it might want to download the file, but it should not download it every time.
I currently use the WebBrowser.Navigate method to do this, but it always downloads the file. But I don't want to actually download the .pdf or .xls file, I just want to determine if the URL exists.
Im just trying to determine if a website exists when i navigate my webbrowser. via messagebox.Ive tried this so far but it wont work:
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted If WebBrowser1.DocumentText.Contains("Action canceled") Then
I am trying to create a function that will determine if a worksheet within the active workbook exits. I have searched many web sites without any luck. Here is the coding I have currently:
HTML Function SheetExists(ByVal sheetname As String) As Boolean Dim oWorkbook As Excel.Workbooks
[Code]....
It errors out at Dim oWorksheet As Excel.Worksheet = oWorkbook.Sheets(sheetname).
The error message I am getting is "Object variable or With block variable not set."
I am working with LINQ to XML in VB (although answers in C# are great, too). First off- my code works, so this is not critical. However, I can't help but think that what I'm doing with conditional logic should already be doable using the LINQ query itself. Here's what I've got:
'Get the Description elements in the ResultData section where the value is "Op Code" Dim opCodes As List(Of XElement) = (From c In xdoc.Descendants("ResultData").Descendants("Description") Where c.Value = "Op Code"[code].....
Please don't be too critical of my method of locating the sibling nodes- the XML files are produced by a third-party testing device and this is the only generic way to get the values I need. What I'm really looking for here is a better way to handle the If block.
i want to loop through toolstripmenuitem child of toolstripmenuitem but i dont fine yet :
For Each mnu As ToolStripMenuItem In Trangchu.MenuStrip1.Items For Each mnu2 As ToolStripMenuItem In mnu ( red word is error ) Please show me) MsgBox(mnu.Text) Next Next
I have mainform which has a menustrip and it contains many level of menuItems every thing works fine, but my question is when I display the form form any MenuItem by the click event and when I close or dispose the called form it dose not display where thelevel where it was called from, instead it come back to the top level menu and no one is selected.
I have a custom toolstrip renderer, which works perfect. But I want to change the forecolor of the toolstripmenuitems too. How can I achieve this?This code should be completed:
Public Class mymenu Inherits Windows.Forms.MenuStrip Public Sub New()[code]......
Am facing the below issue while converting my application from vb6 to vb.net.[code]The menu is getting displayed always at the top left. I need to set it exactly as wher I right click.
I have this: For Each oToolStripMenuItem As ToolStripMenuItem In oToolStripMenuItemMain.DropDownItems '... Next First line produces an exception because it runs into a ToolStripSeparator. How to modify this loop so it won't?
I am having trouble figuring out a way to add click events to ToolStripMenuItems generated off data from a ListView object.In short, i have a ToolStripButton called 'View', in that i have a ToolStripMenuItem called 'Group'- What i have already accomplished is adding sub-items to the 'Group' ToolStripMenuButton. These items are based of ListViewGroups inside of my ListView.
Here is the code for what i've done so far:
Code: Private Sub ToolStripButton3_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles ToolStripButton3.MouseEnter 'LOAD GROUPS INTO MENU LIST GroupToolStripMenuItem2.DropDownItems.Clear()
[code]....
As you can see, this will generate a ToolStripMenuItem inside the 'Group' ToolStripMenuItem for each group that is located inside my ListView- as well as add a constant ToolStripMenuItem, 'All', for viewing all groups again.What i am unsure on how to do is program in the OnClick Event for each of the generated ToolStripMenuItems?
I have in a menu a ToolStripTextBox where the user can enter a CASE NUMBER to FIND. And I have a ToolStripMenuItem below that says QUICK FIND - clicking this will find the case you put in the textbox. Tabbing out of the textbox puts you at this TOOLSTRIPMENUITEM so that ENTER on the keyboard will trigger the FIND. I want to make it so that pressing ENTER while still in the textbox will trigger that same TOOLSTRIPMENUITEM action. Do I have to trap keypresses or is there a more natural way to accomplish this?
I'm trying to do MVP where I have a view specific model that the presenter manipulates and the view binds to. There is no other connection between the presenter and view (the view fires off commands to the domain model via a gateway type pattern).
As you can guess, this makes the ability to bind to any property of any object really important.
I'm having trouble finding the correct way to bind to the Enabled property of a ToolStripMenuItem. Most controls have a .DataBindings property, but this one seems to lack it. I haven't found much info online about how to do this. Is it even possible?
I have single ContextMenuStrip attached to more controls.In use the Opening event of ContextMenuStrip to filter/disable some context entries.In this case the property ContexteMenuStrip.SourceControl is set correctly.The problem I have is on the Click event of a ToolStripMenuItem. This item is inside a ToolStripDropDown. I get the parent item with code:
Dim tsmi As ToolStripMenuItem = DirectCast(DirectCast(DirectCast(sender, ToolStripMenuItem).Owner, ToolStripDropDown).OwnerItem, ToolStripMenuItem)
How do you change the color of a toolstripmenuItem when it is selected?
When Clicked on to open up the drop down menu.
I can change the Background for everything else, but when I click on the toolstripmenuItem the dropdown shows up correctly but the MenuItem changes to an incorrect color.
I understand that Checked is a boolean, which is not the case of CheckState.I understand that CheckState also have a undeterminate possible value.But I don't understand why we have them both. I think that CheckState would be sufficient. What is the need for Checked ?
I have a context menu attached to a panel, that should mirror commands available in a toolbar menu.Currently in my MouseUp event, I set the enabled state of the MenuItems, and add them to the context menu:
So I have a ToolStrip menu item "New", when pressed it creates an MDI child window and adds new toolstrip menu item to the parent window and when clicked it focuses on the window I created before, so I could easly navigate if I have loads of windows. This code perfectly works in VS2008:
Private Sub NewToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NewToolStripMenuItem.Click Dim frm As New Form() Static ic As New Integer ic += 1
I'm developing an application which is having Menustips with few elements. My structure is as follows;
Add-on Modules |_ Data Export | |_ Back Office export
[Code]....
I set the visibility in each leaf element as per the permission given in DB. But I want to set visibility=false in case all the leaf elements are set to false.
e.g If POS interface and Backoffice Interface are set to False, Then I need to hide the Parent (Interfaces) too.
here is what i want to do have a ToolStripMenuItem in a ToolStripDropDownButton menu what i want to do is have an option to not hide the menu when the ToolStripMenuItem is clicked so i wrote the following:
I had a lengthy subroutine with handler routines, like this, before:
Private Sub CompMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _ ToolStripMenuItem3.Click, ToolStripMenuItem4.Click, ToolStripMenuItem5.Click,
