View 1 RepliesWe are attempting to run a batch file that will result in a submission to a help desk ticket system. When we run the batch file from command line on our W2003 platform, it works successfully. When we run the same file, called from our vb program, using shell or process info, it does not. With shell, we can see the batch file being called, but it is not resulting in update to the help desk ticket system. The vendor of the system believes it is a security issue. We are signed on as Administrator while running this. We set security permissions of cmd.exe to include Batch, per KB867466. What else should we be doing or looking at?
View 8 RepliesI am using Compact Framework 3.5 on a Symbol MC50.In my Sub Main it first checks to see if a database exists. If it does, it shows a login screen using the following code:
Dim login As frmLogin = New frmLogin()
If login.ShowDialog() = DialogResult.OK Then
Application.Run(New frmMain())
End If
This all works correctly and, when I close frmMain, it exits the application as expected.However, if the database check in Sub Main fails, I call the ShowDialog() method of another form that is used to create and fill the database from a live server. Here is the code for calling this form:
If Not File.Exists(SETTINGS_LOCALDB) Then
databaseExists = False
MessageBox.Show("Local DB does not exist. The database must be created before using the application.")[code].....
All of this code is being hit and frmMain does indeed load. However, when I click the close button in the top right nothing happens, no event occurs. Its as though the Windows events are not occurring.
I got a combobox, that when the texted is changed, its supposed to run a query to update a field in my database. Here is the issue The event im using is TextChanged, well unfortunately when the page loads, it changes the text when populating the values. Is there a way to make this event wait to fire until after the list is populated? Ive ran into this problem before with datetimepickers, but I was able to offset it with a boolean, but this combobox is calling the textchanged event everytime it adds an item to the list.
View 1 RepliesHave been playing around with user controls and had a go at enhancing the textbox. Everything I done works fine except now I can't seem to tab out of or into the control. I haven't changed anything except the borderstyle and coloring when the control gets the focus.

(Using VB 2008 express). I'm fairly new to vb and I can't find any information on this anywhere. I have an app that clicks a download button on a web page from a web browser control. This works so far, a download box comes up asking whether I want to save or open the file. I want to be able to select the "Save" button and then chose a name and then click enter. Is there a simple way to tab over to the save button and click enter?

View 1 Repliesi'm creating a program called Workshop Selector. It has 3 list boxes, one with the 5 workshops, second with 6 locations, and the final is the list of costs. The user selects a workshop, a location, then hits the Add Workshop button, which calculates the costs and adds the cost to the third listbox. Soo, to my question.
There is an additional button called Calculate Total that adds the values of the costs in the cost listbox and displays the total in a textbox. The code i currently have that works just fine is --
Dim one, two, three, four, five, total As Integer
lbCost.SelectedIndex = 0
one = CInt(lbCost.SelectedItem.ToString)
lbCost.SelectedIndex = 1
two = CInt(lbCost.SelectedItem.ToString)
etc..etc..
total = one + two + three + four + five
tbxTotal.text = total
While this works, i have no idea of knowing how many times the user will add a cost to the cost listbox. therefore id have to make many many variables, and other issues occur.So is there a way i can do this with a for loop? declare a global variable like
Dim costcounter as integer
then at the end of the add workshop cost btn click procedure use:
costcounter = costcounter + 1
That way i kno the exact amount of times the person added a cost?
Then create a for loop like
Dim intcount As Integer
For intcount = 1 To costcounter
code....
Next
Would this work somehow? but what code would i have to input within the for loop to scan each selected index, and then return values that can be added together and displayed in a textbox?
In C# Windows Forms, a user control's InitializeComponent is called from the form's/control's constructor. When I create same scenario in VB.NET I don't get a constructor, and I can't locate a place where InitializeComponent is called.I need to call my code between InitializeComponent and when the control's Load event is raised, preferably still in the control's constructor. How do I do this in VB.NET?

I have an application with a splash screen which gets shown before the application starts. One of the requirements of the application is to allow users to restart (or atleast clear the form) so that other test cases can be ran. Because there are so many forms and variables, we elected to simply call Application.Restart() to accomplish this.
What we would like to do now is disable the Splash Screen when Application.Restart() is called. That is, only show the Splash Screen when the application is initially started, not when it is restarted.
I am fairly new to VisualBasic .NET (2008). I'm creating an application that, when a number is entered into the textbox, a new form window is created and populated with buttons. Each button starts the same command, but with a different parameter (the parameter being the pertinent record number found by the search).'The records are asset tag numbers.The procedure works fine if there is only one result.But the search allows for partial numbers and that's where the trouble begins.If two or more results are found, each button is configured with the last number found. The button being clicked doesn't tally with the proper ID number.[code]
What I didn't count on was that the event is only called when a button is clicked. When buttons are made, they are not assigned at that time.I've had problems trying to carry over the (current value) for pcArray(i), hence having it populate that form3_text field. When trying to add in a second object to be passed, I get the following error:"Method prtivate sub DynamicClick(sender as object, pcNameInfo as object, e as system.eventargs) does not have a signature compatible with delegate sub event handler with delegate 'delegate sub eventhandler(sender as object e as system.eventargs)."I tried manually entering a "Delegate sub eventhander" with the pcNameInfo object and VB 2008 ignores it.What can I do to get each newly made button to be told to run the RemoteIn(pcArray(i)) process properly?

View 1 RepliesI build my first Project composed of several forms and it�s working just fine. Id like now to redesign the project as a MDI Application. Once created the parent form, I can create child forms but thats not what I need. What I would need is convert my already designed and working forms to MDI child forms. How can that be done?
View 1 RepliesI have a program that someone else designed the form on and sent to me to populate the code. I am not sure what could have been done to cause this problem, hoping for a quick oversight on my part. There are several fields of textboxes that the user enters numbers in. Normal behavior for textboxes is when you tab to them the current contents are highlighted. On one of these textbox fields, and only that one set of textboxes, the contents are highlighted like normal at first, but after the user edits the content of the textbox, if you tab to it again it will go directly into edit mode instead of highlighting the contents. Each textbox in the field does this individually, so if you just edit one, all the rest will continue to highlight contents until you edit them as well. It appears you don't actually have to change the value of the textbox, just entering edit mode and getting a blinking cursor is enough. I cannot find a difference in the properties of these textboxes compared to the rest.
View 4 Repliesi was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]
View 1 RepliesI have the following line of code in my program:
JCL_History.Enqueue(JCL_History(I))
This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:
Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))
[Code].....
In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.
After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.
So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.
Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.
I believe I need to add some more code to make this work but I'm not sure what else to add.
When the code executes the report is displayed but no data is shown in the report.

I recently found an awesome tool called "Freemind" that is called a 'mind mapping' program. It's similar to MS Visio but way cooler and more automated.I reeeallly would like to integrate this into a VB.net Form, but how?

I have a couple of questions regarding the use of multiple forms within a single project.I'm currently using a button to load a second form so that the user can select different options and then load those options from the first form.Basically, I have a check box on form2 and I want form1 to be able to know if it is checked. I thought I could just use:
if CheckBox1.Chcked = True Then
Etc.
End If
But, when I do, I get an error saying it can't identify the object I'm referencing.Also, when I open the second box and I click my "OK" or "Cancel" button, the page reloads and then I must press it a second time for it to actually close.This is the code I'm using on my first form:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim frmDialogue As New frm2Toolest
frmDialogue.ShowDialog()
If frmDialogue.ShowDialog() = DialogResult.OK Then

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
Me.DialogResult = DialogResult.OK
End Sub
