I'm translating my VB.Net application, and I need to loop through all the controls on my form. Using a recursive function such as
[Code]...
But there is obviously an inheritance problem, since CommonDialog objects are not controls.
Is there a way for me to loop through really all the items displayed on my form?
How do I revert a form including the controls back to a original state without closing the app? For example I got a picture box and 2 buttons in a form..

I have created a customised checkbox control (only the text and border appearance has been modified), and wanted to loop through them in a User quizto see which have been checked and are correct. I have used the Tag property (set to 1 or 0) to identify incorrect answers, and tried to loop through with the following code:For Each thing As GMAW.MyCheckBox In currentParent.ActiveMdiChild.Controls
View 7 RepliesI am trying to find a way to use the UseCompatibleTextRendering properties on each control on my form. However, it does not seem to be an option when i use the following code below:
For Each ocontrol As Control In Form1.Controls
ocontrol.UseCompatibleTextRendering = True
Next
ocontrol does not seem to have that option but has all other options for the button. If i do Buttion1.UseCompatibleTextRendering = True then it works just fine.
i have a winform and i have about 30 labels and 30 picture boxes on it. What i would like to do is fill each label and picturebox with a value and image from a backend database. I could have easily done this in vb6 using control struture , for eg.
for x = 1 to 30
picturebox(x).image = value from database
label(x).caption = value from database

I did a quick net search and found this which works great for looping through all the buttons to disable them. These buttons are located right on the form.
For Each ctlControl In Form_BLAH.Controls
Select Case TypeName(ctlControl)
Case "Button"
ctlControl.Enabled = False
End Select
Next ctlControl
However...when I tried it on a form where the buttons are contained within a Table Layout Panel it does not work.

View 1 RepliesI am converting a program I wrote in VB6 to Visual Studio 2010 VB.Net and have run into a problem. I am trying to cycle through 20 form elements on a form that all have the prefix 'chkCustomerItems' and then have a number 1 to 20 behind them. I am using this with a database lookup so that it there is a database entry it then applies the database item name to the checkbox's text field and turns visibility on. Here is the code I wrote:
ConnOpenClose()
Rs = New ADODB.Recordset
Sql = "SELECT * FROM CustomersItems;"

When it runs, I get a NullReferenceException error. This is basically the code that I used in VB6 (with some changes for .NET infrastructure).

i have two forms, one form is for accepting the details of the customer and other form is to export the customer details to excel. In the second form i have a listbox which contains all the names(rather captions) of the controls on the form1. like Items In Listbox -> Map onto control of Form1 customer Name -> txtcustomerName Address -> TxtAddress. What i want to ask is what is the best way to get the values from the form1 based on the selection(s) of listbox in form2
View 1 RepliesI'm making an editor for my app. which allows the user to change properties of the controls including the font.I'm storing the values in a collection but I'm having trouble re-setting the fontstyle from the stored value. I'm storing the font information like so...
FontString = SpeedGroupbox.Font.Name & "|" & SpeedGroupbox.Font.Size & "|" & SpeedGroupbox.Font.Style
EditedControlsCollection.Add(FontString, "SpeedGroupbox.Font")
We're trying to access the Sent Items folder in Outlook 2007 (using Exchange) but the test for TypeOf(i) Is Outlook.MailItem in the below code snippet always returns False.We know we have the right folder because a test for items.Count returns the correct number of mail items.Inbox messages are fine. If we change the folder from olFolderSentMail to olFolderInbox the test for TypeOf(i) Is Outlook.MailItem passes and it's quite happy to show us the Subject.

View 5 RepliesI have 20 controls that I created on a form. the names are like btnRing1, btnRing2, btnRing3, etc.
So I have a do while loop , and I have my variables in place. One line of code is "btnRing1.Start = PlrName" So PlrName is a variable, pulling that info from a database. I don't want to list each btnRing1, 2, 3 in each block of code in my loop.
Is there a way to use the name btnRing + 1, or something like that so I don't have to list all 20 controls in my code.
I know I can dynamically build the controls, but I can only have 20, so I need to have a little control on the numbers. So I need to have the controls already built.
I'm trying to save each item in the listview to the database.Below is my code in saving items in the database. The MISSING CODE HERE is where I should place the listview item.

At the moment I have a listbox and two buttons. The first button will add files from a directory to the listbox, whilst my second button processes a single txt file inside a folder to remove certain words, then save the processed document as a copy.
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
' Replace common words and all symbols.
Dim wordsToReplace() As String = {" cat ", " hat ", " that ", ", ", ". "}
Using sr As System.IO.StreamReader = New System.IO.StreamReader("C:User est.txt")
' Read the entire file into memory.
[Code] .....
What I am trying to do now, is rather than process documents in a static folder, I want to process the documents that are inside my listbox, and save the new copies back to the list box (repopulate the list box with the processed txt files, I hope that makes sense). What I think I need to do is loop through the listbox and take the file path for each item, process it, then feed these back into my listbox.
When one is clicked, would like to be able to have it checked, and uncheck all the restCheckOnClick will not uncheck the rest (I want an effect similar to radio buttons).My first plan was to loop through each item in the ToolStrip Items() array, however these are ToolStripItems (which are a base class) and thus do not have the Checked property. So then I thought about using CType to convert them to ToolStripButtons, which do have the Checked property, except what should I do about the ToolStripSplitButtons?I basically want to say, "if this ToolStripItem is as ToolStripButton, then uncheck it"
View 3 RepliesI have a dynamic webpage that loads a user control multiple times, including loading the user control within itself as many times as needed. Within the user control there are four controls: Title Label, Repeater, Placeholder and within Repeater a AjaxControlToolkit Rating control.
The structure can look like the following:

UserControl (repeater hidden, no data)
Placeholder - [UserControl]

how do I efficiently loop through this type of structure to find the rating controls?

Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?

View 4 RepliesMVC 3, VB.NET. I have a form in my app that gets basic information from the user and then allows them to upload a resume. I am accomplishing this right now by using a redirect to a different form that's only purpose is to select the file for uploading and then submit it.. Sloppy in my opinion.. I have tried to do it from the same form but the file is being lost on submit.. While I am not certain of it I believe it is because I am not using the correct syntax in the form to handle the file.[code]

This seems like it should be something very easy to do, but every time I approach this issue, I end up w/ solutions that feel "less than elegant" Here is my basic question: If I am looping through a dictionary that I have ordered in a particular way, within any given point in the loop how can I "peek" or get reference to a dictionary item 'x' places ahead of the current item without changing the current enumerator? For instance:
Dim tempDictionary = New Dictionary(Of String, String)
tempDictionary.Add("TestName1", "TestValue1")
tempDictionary.Add("TestName2", "TestValue2")
tempDictionary.Add("TestName3", "TestValue3")
[code]....
unfortunately searching the web i cannot find a decent example that allows me to loop through a winform to make sure comboboxes items are selected.basically what i would like to do is check the form if the comboboxes have been selected if not then highlight them yellow and set the focus on them.
View 8 RepliesI have some code that I want to apply to many objects (Pictre Boxes) and I was unable to loop through the objects via a For loop and am currently forced to copy paste the code for each Image Box.

Is there a way to do something similar to this:
For i = 1 To 10 Step 1

so this is the problem our professor gave us. the user given a chance to log-in correctly 3 times, assuming that a user log-in his/her password incorrectly there will be a loop, counting its no. of attempts. and if it exceeds to 3, there will be a msgbox assuming "you log-in incorrectly 3 times" etc. here in my code it counts but the msgbox ("try again") shows 3 times.
I have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.
Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....
I'm using the following code for doing so:
Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged
' defines a new connection to the database
Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")
