[2005] Passing A Value To An Invisible Textbox Not Working?
Jan 23, 2009
in my form, i have a textbox in which its visible property is set to false. this textbox is bound to my table's primary key column.
whenever i try to add a new record, it automatically generates a value and i can see that when the visible property is set to true. now when i set it to false and do a messagebox.show(textbox.text), it shows no value. so i set the visible to true and then the messagebox does show a value.
i don't want this textbox shown in my form but i need to get the value from the textbox when the primary key value is generated.
vs2008, Binding Resource & Binding Navigator by Wizard I had drag a field from a table into the form, and the wizard had created the binding resource and the binding navigator of the required field including the 2 field I use as PK Autoinc "ID" and PK "site". I run the form, and in the BindingNavigatorAddNewItem_Click I put
I' ve got a thing that I'm wrking on, but it's one thing that isn't working.I have a backgroud (fire) and a man. But it doesn't become visible (the area outside the man). Is there any code so I can make a certain color invisible (not so you can see through the
Is it possible to make tooltips invisible in VB.NET 2005? The reason that I ask is because I need to store some data about each node in a treeview control, but I am already using the node's tag value to store an object that represents a "SuperToolTip" which is a control in DevComponent's DotNetBar utility. So I do not want the tooltip to be visible, since I am already displaying a more feature rich tooltip for each node. I guess I could store an array in the tag, that would contain the object that I needed, as well as the string info I need for the node as well.
I am currently using a DevExpress (10.2) Banded GridView within my Visual Studio 2010 project. It works great except I was have an area where I allow the user to choose which columns they want visible or invisible. I noticed that if I make all the columns within a band invisible the band still remains and gives an empty column in my grid. I was wondering if there is some way to automatically
I have 2 textboxes one for datetime picker and another for entering the name. i waant to make the datetime textbox invisible when the form is executed & when i press save the data from both textboxes should be saved into the database.
I am trying to pass the datatable of a search query to another page and bind it to a listbox. The problem is the the listbox just displays system.data.datarowview and no results.
I have listed the code below.
First page SQL and session store: Protected Sub btnSearch_Click(sender As Object, e As System.EventArgs) Handles btnSearch.Click
Why is this not working for me? What is wrong with my code below? I am trying to read a stored proc and applying values to labels. Getting error that say "Incorrect syntax near CareerInner".........

I am passing value via an object property form1 to form2 my class was working before, but I guess when i create the instance of the form2 in form1 my calls in my class no longer work properly.

So I've got 2 unbound datagridviews, and am providing a push/pull interface where the user can move records from one to the other.
Grid A is read-only and the selectionmode is set to FullRowSelect. Grid B has a read-only DataGridViewTextBoxCell, an editable DataGridViewComboBoxCell, and an editable DataGridViewComboBoxCell.
Because the grids have different columns, but represent the same records, my notion was to create the datagridviews with the same column structure but hiding certain columns, and then just move the DataGridViewRows back and forth between the two, which seams to work.
The problem is that if I go into column 2 or 3 in grid B, I get "Current cell cannot be set to an invisible cell".
I can select cells in column A and I'm fine. It should be noted that on grid B the hidden columns are 4-7.
I know there's a problem when the CurrentCell attribute is set to a hidden cell, but I'm clicking visible cells. I inserted a breakpoint on the CellClick event of the DGV, and again for column 1 that works fine, but on columns 2 and 3 it looks like the error is occuring before the event even gets fired.
Is something in the background setting CurrentCell to one of the hidden cells before firing the event?
I have setup a page in Excel with several textboxes for data entry. I would like to be able to tab from textbox to textbox so I can enter this data as quickly as possible.
I'm having trouble passing an array of a user defined type to an procedure in a COM DLL. The prototype for the procedure i'm using is this:
HRESULT STDMETHODCALLTYPE GetData( /* [in] */ DWORD dwCount, /* [size_is][out][in] */ CSimData *puData) = 0; CSimData is a structure which is also defined in the interface.
I'm trying to call it with the following code but am getting an exception:
Dim temp(1) As MACHPLANTSIM18Lib.CSimData temp(0) = New MACHPLANTSIM18Lib.CSimData temp(1) = New MACHPLANTSIM18Lib.CSimData
[code]....
The exception i'm getting is "COMException was unhandled - Exception from HRESULT: 0xC0000005" It looks to me that the array isn't passing properly to the COM function. I'm able to send a single object, but when I do an array of objects I get this exception.
Button1 click event Dim array1 (3,3) as string array1 (3,3) = "BLA" End Event
Now, in the same class, I have another button.
When I click on this button2, i want to use this array to stream files to textfile.
The problem is that I cannot pass data from button1 click event to button2, as I have to declare the array again, and that causes array to lose data on button2 click.
If I however, declare array on top of class, I get a funny error sying out of index range etc.
I have a datarepeater with a textbox that shows a row id in a sql server, for each instance of the datarepeater there's a button on the datarepeater that I'd like to have the user click, and that would send the text from the textbox on that row to another form, possibly just to a textbox on that other form. anyone know the code that would accomplish this? i've been looking all around but no luck, (i did have luck with the item_cloned solution for combobox's in datarepeaters tho..
I have 3 forms, the form one is an intro, form 2 loads a user and form 3 displays a user. i use the streamread / writer to load values on form 2, then when successful it loads form 3 and the vaules are transferred perfectly, now to save time i changed the start up form from form1 to form2 (saves having to skip every time). so after having all the code load and transfer i wanted to see it in action and then the issues started.
I have a Windows Form Application that has a few TextBoxes, Buttons, and a couple of ListViews. One of the TextBoxes takes an entry (usually by a barcode scanner or the user can type text and hit the TAB character) and then that searches through some data structures and if found it modifies the color on a row in one of the ListViews and adds a row to the other ListView. What I want to be able to do is to put the focus back on the Textbox that takes the input from the barcode reader.The problem I'm having is that the TextBox doesn't always get focus back after a scan. Sometimes after a scan it looks like the focus is on one of the splitContainers. I can manually take the mouse and put the focus back on the TextBox, but that would be kind of inconvienient for the user. What I would like would be for the user to be able to scan (which enters text into the textbox and then TABS out). The TextBox's Leave Event fires and runs the code that manipulates the ListView's and then at the end the leave event code clears the textbox with TextBox1.Text = "" and then calls TextBox1.Focus()
I've tried using TextBox1.Select() and/or TextBox1.Focus() and neither one works. I even put in a Apllication.doEvents() so that any pending action that might cause focus to change will happen before I call the Focus() or Select() code.My guess is that maybe it has to do with some race condition on actions that pull focus away, but how can I keep focus on the text field and still allow the user to use the mouse to press the EXIT or SAVE buttons or even click on an item in one of the ListViews (which doesn't do anything right now).
I do have a check in the TextBox.leave event that checks for empty values using
I have a function that search database based on the 2 textbox value. I have a difficulty to call the function and pass the text box value to the function. This is my function: So I get this error: {"Object reference not set to an instance of an object."}

We are using VB 2005(Visual Basic.net) with SQL server as database and MS Access for the Reports. Right now we are passing the footer label from our VB app to MS Access for a selected report. If the user closes that report(not closing access) and opens another report the footer label is not being displayed. Is there any way I could send the footer label to all the reports in Access as soon as I open the database.Right now in below code we are sending the footer label just for the report selected. Is there a way to send the footer label to all the reports that are existing in the Access database.
Here is the code we are using right now.

From what I understand, when you use AddHandler you're not actually calling a Sub, so you can't pass a parameter. I'm confused on what to do though about this. I've just populated a DataGridView and added a button to it in the codebehind. I'm then using an AddHandler to add a click event to the button. So when I get to the click event, I need to be able to access to the datagridview because clicking the button takes data from the datagridview and loads it into excel. What would I do about this. This is my Method where DataGridView was just populated
Dim btn As New Button btn.Name = dgv.ToString() btn.Location = New Point(0, 0)
I am working with some code that uses array lists and I am using some of these to pass data back and forth like this: whatFile = (sideLookUp(x)) and its working, BUT when I turn this code into a sub/function then I call it I get problems, like double to string errors, even though its all set to double.

I am using VB 2010 express and am trying to make a program for a project that generates lottery numbers in a specific way. What I have is two forms. Form one has two text boxes and a button. Form two has a checkedlistbox that is pre-populated with numbers from 1-56. What I am trying to do is have the program open to form1, the user presses button1 ("Select Numbers") which opens form2. From there they will select numbers they want to pick from (narrowing their pool of lotto picks to only numbers they want to use). Then when they hit select, I want the numbers they have checked to return back to the textbox1 on form1. HOWEVER, I also only want 5 numbers, randomly selected, from the pool of checked numbers the user selected on form2 to return to the textbox1 on form1..... I may be in wayyy over my head, but I have all of the forms designed and I have been close to getting the forms to at least communicate, but still far from doing what I have described I am trying to do.
I have a DataGridView which I named CallnumberDataGridView and I also have a TextBox which I named txtCallnumber.

I have a listview with process that are running. my goal is to pass the "path" of the process to a text box when someone clicks on a selection.but my code isnt working correctly, this is what I have:
Private Sub lvwProcBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lvwProcBox.SelectedIndexChanged Dim pID As Integer = Int32.Parse(lvwProcBox.SelectedItems(0).SubItems(1).ToString) Dim proc As System.Diagnostics.Process = Process.GetProcessById(pID)
[code]....
and of course the text boxes path changes to a different path if a different selection is made?
Dim Selvk As New Selvkost2 Selvk.PassedText = TextBox29.Text Selvk.Show() in mainform and the code

I am using following code to connect to my database. Dim conStr As String = "Data Source=.SQLEXPRESS; ![enter image description here][1] AttachDbFilename=|DataDirectory|dbTest.mdf; Integrated Security=True; User Instance=True" Dim sqlQry As String = "SELECT * FROM [tblTest] WHERE ([Name] = @Name)" Dim dAdt As New SqlDataAdapter(sqlQry, conStr) Dim dSet As New DataSet()
Then filling adapter with dAdt.Fill(dSet, "tblTest") And then I can use the data the way I want.
My question is: How to pass the value of parameter that user will give through a text box on my webform. Dim sqlQry As String = "SELECT * FROM [tblTest] <b>WHERE ([Name] = @Name) I mean how to pass the parameter value to my query?
I'd like to have a link on my VB form that will open an InfoPath Form with some information already pre-populated (name, date, etc.) with information that is already filled in on the VB form. I'm pretty sure there is a way to do this, just haven't figured it out yet.
i'm not 100% sure about sql server but i think it doesn't accept null value for date type columns but in oracle, a date column can accept a null value. and since i'm using oracle, this is causing some problems because in my form, a textbox item bound to a date column will not accept a null value. reading thru some threads, it would seem that it is not possible to pass a null value to a date type in .Net.
