I'm trying to make a string inputted on a separate form's text box adjust the value of a string on another form. Is there a way to do this rather than exporting the data to a file and retrieving it on the other form?
View 7 RepliesI have about 10 boxes on my form1 that the user will populate, I am looking for a "Best Practice solution to pass the values across to form2 and form3. Would like the user to be able to edit the value on either form and have the chnage carry over to the other forms.
View 5 RepliesI need a nudge in the right direction. I have a user control that has the main form and it calls a secondary form to gather some additional information in some cases. I need to pass the information back from the secondary form to the primary user control form so I can validate the data and save. In the secondary form, I have the following code:
Dim myFrm as new frmOperationComments
myFrm.OperationComments = [comments from form]
myFrm.OperationDate=[Date from form]
I have tried creating two public properties on the user control and setting them, I have created two properties in the user control form called OperationComments and OperationDate. I can set both of them, but when I close or hide the form and go back to the main user control form, the values for these properties or variables are not set. How do you set the values on the main form from a calling form within a user control?
Is this not the correct way to do this? I get an error with it but if I change it to only one value then it works.
If dt2.Rows(0)("STATUS") = "COMP" Or "CLOSE" Or "CAN" Or "INCOMP" Or "WAPPR" Then
dt.Rows(currentRow).Delete()
End If
When I click on button1, employee_id and P values need to be transferred from button1_click to Cal_Category13() and go through all the calculation. After the calculation, udtnew.X and udtnew.MTD values need to be transferred back to button1_Click
I've no problem to return multiple values Cal_Category13().MTD and Cal_Category13().X from Cal_Category13() to button1_Click but i've no idea how to transfer employee_id and p values from button1_click to Cal_Category13().

I have to compare an item value in two tables. these two tables are on different database(same server).
I have succesfully generated sql query to return both table values.
the query runs in sql server without any problem and gives the results.
The same query i used in vb.net doesnt gives any result ...
It is resulting with no rows.
Does the connection to multiple databases wont work from vb.net.
The following classes are used to get the result ...
SqlConnection
SqlCommand
SqlDataAdapter
SqlDataAdapter is showing with no records returned. The same query returns the results in sql server query window...
I have four textboxes that only accepts numeric data.On each box is a corresponding checkbox.I want to have a button that will get the total sum of all textboxes wherein their checkboxes are on checked state.
View 1 RepliesTo start things up, I have a DLL called clsEmployeeModule, containing forms frmEmpInfo and frmAddEmpName. frmEmpInfo contains a textbox that when clicked displays the frmAddEmpName. Now the latter contains three textboxes (firstname, middlename and lastname) and a Save button. Once the user clicks Save, the values from the three textboxes will be concatenated and displayed as a full name back in the frmEmpInfo form.Below is the code snippet calling the frmAddEmpName:
vb
Private Sub empname_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles empname.Click If genInfo_edit = True Then call_addempname.Text = "Edit Employee Name" End If call_addempname.Show() End Sub
And here's the code snippet from the frmAddEmpName:
vb
Imports clsEmployeeModule Public Class frmAddEmpName Dim callempinfo As New clsEmployeeModule.frmEmpInfo Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click mnFname = firstname.Text
[code]....
When I debugged the program, it showed that employee_fullname was successfully populated with the concatenated values -- however, that wasn't the case for the empname textbox.
Im very new to programming all together, but Ive recently been messing around with Visual Basic 2008..
1. When using multiple forms, how do I make a form be the form that opens with the program (default form?)?
2. How do I assign a button to open a second form?
With what I'm trying to make, I have both forms ready, I just need form2 to be the one that is the first to open when running and I need the code for a button to open form1.
I have a VB Solution with a dozen forms trying to implement invoice system.My main form (Say Form1) only has a design to create , Edit or Delete Customers.My form 2 will be opened if Create button is clicked. In my form 2, I have textboxes where user can enter Customer details and click on SAVE. My doubt is here....On clicking this SAVE button in Form 2, I want a INSERT command to happen on the MSAccess's Database table called Customer (which I have already created... this table does not have any records as of now). In my form 1, I added a MSAccess Database with a Connection String. In my Form1's code I have code like this[code]...I got this piece of code from this link [1]: vb.net - sharing mdb access connection among multiple forms/Now, I do not know what more code does this require to INSERT records from my text box into the Customer table's fields.
View 1 RepliesSo, I'm trying to do things according to accepted convention as much as possible.
I have a DataTable that holds data that is read in from an XML at the launch of the program. This DT contains data about folders that are added by the user. It is primarily accessed by a single form, but another form used for Adding/Editing folder data will need to update it.
So, what is the best way to handle this: Currently the DT is created/maintained in the main form (FolderPad) that uses it. Would it be better to put the DT in a public Module for access, or allow the add/edit form to access the reference to it in FolderPad? Or is there a more accepted way to do something like this?
I have used CSV files before for a simple database of about 12,000 items - this was a simple one page form... Now I want to have the same database but with the data available to multiple forms at the same time.. eg.. Form 1 displaying persons 1,2,3,5,7 name, addy, phone etc and form 2 pulling info for persons 2,3,4,8... Is this possible with CSV files?? or even XML?... The only other thing is that I do it all in .NET 2.0....
View 3 RepliesI am trying to display(in a status strip label) the user name of a user that is currently logged in across multiple forms. The initial form is a log in screen that queries an SQL database for the user name,password,and user type. If the query returns a match,then a different form is displayed based on the user type. How do I retain the user name of the user that is currently logged and display it in the label?
BTW,it's a point of sale program.
I have simple columns and their respective sums. However, I exclude 1 particular value from each sum, like so [code]...
Now I need to exclude another value ("Awaiting Progression") from a second column called "PROGRESSION".
Since I already exclude value based on 1 column called CATEGORY, how do I change my =Sum(Code.ExcludeOthers(Fields!CATEGORY.Value,Fields!ACTION_PLAN_NEW.Value)) to exclude a value from the PROGRESSION column if it's = ("Awaiting Progression") ?
i.e. How do I exclude multiple values, depending on values in 2 columns in SSRS 2005?
In a label box, I want to list a couple of websites, email address along with some text. How do I go about it?
Potential uses- As a Help > About dialog box where websites, email of the author can be listed.
To make things as easy as possible for the user, and encourage visiting of the mentioned websites.
Simple text will be ignored, while standard blue color, underlined text with hand mouse-cursor will need no thinking on user's part.
I have the requirement to create an application that has multiple front ends developed using Windows Forms, WPF, ASP and Compact Framework Mobile Forms.I would like to be able to create a series of obejct representing the business logic and have this logic accessible from the various front ends available. My first thought was to use remoting as I'd like to be able to pass the business objects back and forth between client and server but the compact framework doesn't support remoting and also transferring a full framework business object to a compact framework business object doesn't seem possible.My next thought was to use web services but again the passing of business objects seems to be very hard to accomplish. Without doing this I would have to create individual web methods for each business operation.
Finally my next option is to use sockets and write the whole client/server logic within some classes and expose them to the UI/Business layer. My only problem with this is it is not scaleable should the number of clients increase dramatically whereas using remoting or web services I can host the solution via ASP.Net.Does anybody have an ideas on the best way forward for this or even have any input on how they would write an application that required a windows form, wpf, asp website and mobile device GUI all of which want to use the same business logic?
I've been investigating and experimenting with the code snippet on this page: [URL] - with some rather undesirable and wacky results being produced.
Why do I need this? I am attempting to adapt this snippet to suit my needs for a day/night system in the game I am working on. I am sure that the correct results can be produced with this snippet, but at the very least I need some guidance as to how I can achieve what I want.

I have googled high and low to find an answer to this but I must be searching wrong.I have an application which has a listview displaying some items that are stored in a SQL Compact database. I am using a second form to add new items to this list directly into the database.When the second form closes I want to call the sub in my first form to refresh the list from the database.
How can I get it to fire the form1 sub routine on the close event of form2
i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.
In VB.net how do you retrieve an value from a object in a different form.
eg:
' on frmMain
MsgBox ("Say ""Hello World"" Mr. " & frmOther.txtName.text)
I'm having trouble adjusting the font style in a RichTextBox and I've seen a few different approaches that talk about single attributes (like toggling bold on and off)... but I'm trying to make it so that my font class can adjust any attribute (bold, italic, underline).
I realize that Font.Style is a set of Boolean flags (a bitfield?)... but I'm not sure how to handle the attributes all at once.
Here is the troublesome code:
Public Sub ModifyFontStyle(Optional ByVal Plain As Object = Nothing, Optional ByVal Bold As Object = Nothing, _
Optional ByVal Italics As Object = Nothing, Optional ByVal Underlined As Object = Nothing)
[Code]....
What is happening to the font? The text should be underlined and in italics not strikethrough...
Is this a logic error or a simple misunderstanding on my part?
I've developed an application that acquires images from my Logitech QuickCam Pro 9000 using WIA. The problem is that I cannot figure out how to adjust the quality of the image taken by the camera. The camera has a 2MP lense, but the program will only acquire a picture of 320x240 pixels, which is the lowest resolution the camera has. How do I tell the camera to take a picture at one of it's other resolutions? IE: 640x480, 960x720, 1.3MP, or 2MP?

How do I change the Windows Speaker Volume (The Main Output Volume Control Volume Value) via VB.NET? I want a way to like indirectly change the whole system's volume like we do it from the Volume Control application on Windows 7
View 1 RepliesIt seems there is no easy solution for adjusting a specific format of a used font e.g. for Text. As I understood in order to change any part of the used format we need to use New Font(...) form of implementation which looks a bit odd to me.
TextBox1.Font.Bold = True
which needs to be rewritten as:
TextBox1.Font = New Font(TextBox1.Font, FontStyle.Bold)
which is no reason that I can see why it should be hard like that.Anyway, here is my solution for adjusting the font style using four CheckBox controls (i.e. BBold, BUnderline, BItalic and BStrikeout).Preview is a TextBox control.
Private Sub SetFontStyle(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BBold.CheckedChanged, _
BUnderline.CheckedChanged, _
BItalic.CheckedChanged, [code]......
I've a form set to size 1240:750. On my PC where I've VB2010 installed, the screen size is set to 1680:1024 and the form can be viewed fine but on a PC with screen size set to 1280:1024 (higher than the form) the form in question is cropped almost a third of it. To adjust the form to everyone screen size I set the below code at load with no avail.
'Autosize form to screen
Me.Height = (SystemInformation.PrimaryMonitorSize.Height) * (0.9)
Me.Width = (SystemInformation.PrimaryMonitorSize.Width) '* (0.9)
Me.MaximumSize = New System.Drawing.Size(Me.Width, Me.Height)
Me.MinimumSize = New System.Drawing.Size(1240, 750)
I have a windows form which contains a group of panels in a flowlayout control. Each panel has a button acrossthe top which is always visible and clicking on it expands the panel to view the other controls on it. clicking on it again shrinks the panel back to the size of the button. A simple form of menu. The flowlayout control has autoscroll enabled and as enough panels are resized (opened) they obviously are too big for the form and a scroll bar pops up.To get the most recently opened panel in the viewable area I use
FlowLayout.ScrollControlIntoView(pnECBF)
where pnECBF is the panel just resized. This works but places the panel at the bottom of the form i.e just in the visible area. I want the user to be able to see the panel AND the next menu button which is on the subsequent panel. So basically what I want is the panel into the visible area +25 pixels for the next panels menu button.

Launch a dialogue window from the main form, and then another dialogue window from that dialogue window. If you close the second dialogue window and call dispose the main form vanishes under any other open windows. This doesn't happen by closing a dialogue window normally, but I am attempting (rightly or wrongly) to stop memory useage creeping up by disposing of it.
So, the question is - what method can be employed to maintain the position of the windows?
