I often face the following problem : when I have a form with lots of controls on it (100 , 200 etc) and I change the name of a control , the IDE goes slow for a few seconds . This is very annoying when I have to change the name to a lot of controls . I believe this is happening because the IDE checks the forms , the code etc to see if there any problem after (re)naming the controls . Of course this is welcome because it prevents a lot of problems , but at the same time it creates some serious problems as well . Thus , I wonder , is there any way I could prevent the IDE from checking all those things in order not to reduce it's speed ? Of course I am talking temporarily . I believe that what I gain by letting it check after every name-changing , I also gain it if I only let it check once (at the end of the name-changing process) .
If NewEntryName.Text = "" And OpenFileDialog1.FileName = Nothing Then MsgBox("Please choose a name for your game.", vbExclamation) MsgBox("Please find your game.", vbExclamation) Else Button1.Text = NewEntryName.Text
at my collage we have to rename all buttons and labels to represent the type of thing the button, label or text box etc do For instance if I had an OK button I would change the Text and (Name) of the button in the Properties section from Button1 to BtnOk, if it is a Label I have to change it to LblOk etc I was wondering if there is a way to change the default (Name) Button1 to (Name) Btn1 and so on so that I only have to click on the 1 and type my description, rather than having to type the abbreviation for the type of object every-time also ?
I have a TreeView that I am using for display purposes only. I don't want the user to be able to select any of the nodes. Setting the enabled property of the form to False doesn't suffice since it changes the entire look of the nodes.
I tried canceling the select action in the BeforeExpand event. It kind of works. It selects, then de-selects the item. I'm going to play around with other events to see
My question is , i have just made a project for my appointments like, Name,Date,Time and Notes and all viewed in a listview grid but how would i save the entrys ?Like to save 1 line i can easly use my.settings but how about mutliple lines ?Here is a screenshot:It would be best to save it into the program like my.settings or something
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim lSingleItem As ListViewItem
There are samples of Runtime copying things, But what I want to do is: Copying a panel formed in the desining level (with the controls on it)The name of the panel formed on Form1 is PanelTaslak:Dim Panel1 as Object Panel1=PanelTaslak.Copy such a description
Panel1=PanelTaslak is considered as when I write Panel1=PanelTaslak Panel1 takes the place of PanelTaslak But I want to get its copy
i'm doing a program, and i'm working with a guy (he's kinda like a teacher) and he's teaching me tiered coding, UI, BLL and DAL.i've been taught to have the UI in one project, and the BLL in another, but they're in the same solution. pretty much i don't know how to declare things from the BLL project in the UI project.
I'm trying to determine the framework version that is installed via the registry. When poking around, I found this key: HKLMSOFTWAREMicrosoft.NETFrameworkPolicyv4.0 I've created the following function to determine if the key exists:
[Code]...
I've verified the key exists, but it keeps returning False.
i know My.Computer.Network.Ping but as alot of people know, it's glitchy and bugged.
I want something that checks to see if it can connect with something, as simple as it sounds.
I'm experimenting with sockets at the moment, but having trouble so i thought i would come and ask here
What i'm up to:
VB IP = Net.IPAddress.Parse(getinfo("settings.inf", i & "IP")) socket = New Net.Sockets.Socket(Net.Sockets.AddressFamily.InterNetwork, Net.Sockets.SocketType.Stream, Net.Sockets.ProtocolType.IP)
[Code].....
However the problem with this it that i pinged 1.1.1.1 and it still connects, ALSO i would like to be able to check a hostname not just an IP to make things more convenient, please help me to find a way to properly check a connection with IP or hostname.
In the following code, a Date variable is declared but not set to anything: Dim myDate As Date What's the proper method of checking if the Date variable is "new" and not set to anything?
For example, getting the lowest date value from an array of dates: Dim dtMostRecent As Date For i As Intger = 0 To myDateArray.Count - 1 If myDateArray(i) < dtMostRecent Then dtMostRecent = myDateArray(i) Next
In the code above, I need a way to check first if dtMostRecent is unassigned, in which case just give it the first value, after which it can be compared with subsequent values. How to check if a Date variable is unassigned.
I've created the following function and thrown it inside of a timer:
[code]...
It works, but it keeps trying to open media player for each process it looks like. I need to continuously run the function so that Media Player opens when it's closed.how to make sure it opens only once when the process doesn't exist?
Can someone tell me why this code works exactley the opposite of the way I thought it should?

I have a combobox (cbKeyWords). I want to make sure tbAddEdit.Text does not already exist before I save. To me I should be testing for a False result not True. But the above code, goes to the msgbox if findstringexact=false and saves the data if it's true.
I have agroupbox control and on this groupbox control there is upto 10 checkboxes, if any of them are unchecked i was going to throw a warning "No checkboxes selected" i'm not sure how to go about it so far i have:
For Each ctrl As Control In GroupBox10.Controls 'Not sure what to do here... Next
I have 22 text boxes that have to be checked to see if the value has changed. I am using the TextChanged Event handler to do this thus:
Private Sub TextStringChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) DataChanged = True RemoveHandler ........
[code]....
The Handler would be added after the data had been loaded. The question is:Is there another way of checking for text changes without having to add and remove 22 handlers.
I'm having trouble using the HasChanges method.I'm trying to get a message box to show if a user hits the edit button, makes a change, then hits the close button without hitting the save button first. From what I understand, the HasChanges(DataRowState.Modified) statement should work.In reality, when I hit the edit button, make a change to a field (zip for example), then hit the close, it just closes without showing the messagebox.Here's my code so far...
Private Sub CustomerForm_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) _ Handles Me.FormClosing
I am trying to have my program check for the existence of a registry key so I do not get a null reference exception error. The key may or may not exist depending on the computer. How can I check to see if it exists and then change its value if it does exist or skip over it to the next one if it does not exist? (I already know how to change the value part of it) Im just not sure how to check for the existence of it for example would be trying to set the value of a key that does not exist called test below... this obviously would throw a null exception error so how do I check for the existence of the key before executing these instructions and then if it does not exist it skips this and keeps going to the next code ?
Dim testkey As RegistryKey = Registry.LocalMachine.OpenSubKey("SystemCurrentControlSetTEST", True) Dim keyval As Int32 ' Set to ON keyval = 1 testkey.SetValue("ON", keyval)
I also check the status of the registry entry on form load
Dim Test As RegistryKey = Registry.LocalMachine.OpenSubKey("SystemCurrentControlSetMYTEST", False) 'Get the reg value. Dim Testflag As Integer = CInt(Test.GetValue("ON"))
I have tried to solve this myself and I know I am probably doing something really silly here what I have is two different registry values that control what is displayed in the combobox on my form RegistryKey1 has the following values:0,1 or it does not existRegistryKey2 has the following values2,3, or 4 the combobox has the following values 0,1,2,3 However here is the problem if the RegistryKey2 is 2 then it further has to be checked if RegistryKey1 is either 0,1 or does not exist
if it is 1 then the selectedindex = 0 if it is 0 or does not exist then the selectedindex = 1 if RegistryKey2 is 3 then the selectedindex = 2
Suppose I have 5 Integers(A, B, C, D, and E) and 5 Textboxes. When the program run, the user is going to input 5 numbers to those 5 textboxes. When a button is pressed, a label will show up and write the textbox number with the biggest number.
I'm very green with VB Express 2008 and am going through the tutorial. I'm skipping over a lot of the exercises as some of it is review for me - I've a fairly solid background in MS Access VBA and forms design there. But I have a simple question on VB Express forms design (I'm not worried about data handling or anything yet).How do I test a form? In my first form on my project, I just press F5 (Start debugging) and it opens just fine. However, I'm playing around with a second form in design mode and can't seem to get it to open to test some of the code (simple msgboxes associated with buttons).
In Access 2003 and earlier, there was a design mode and form view. The Access design mode was the equivalent of the design tab in the VB project, but I can't seem to find the equivalent of the Access form view in VB so that I can open that form. VB F5 only seems to open the first form.BTW, is VS 2008 the correct tag/prefix for this question on VB Express 2008? I see there's a separate tag list - is there an approved list of tags aside from the prefix before the title in the posting screen?
If txtGradeObs.Text = "" Or Dir(txtGradeObs.Text) = "" Then MsgBox("Specify the Grade job of Obstructions", vbExclamation, MsgBoxTitle) Exit Sub End If
I get an error if the drive does not exist - i.e. G: rather than C:. It used to work in VB6. How can I get it to work.
I want to make a program where I can chose a COM port (For example COM 1), then check if it's working. It would be really useful for me, seeing as I work a lot with broken COM cards.
