In my winform app in VB.NET I want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips don't seem to change when I choose another language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR & nl-Nl folders in the same location as my program?
View 4 RepliesOk, so I know I have to change the labeledit to true but that doesn't change the selected node to be able to edit, so how does that work?
Along with renaming I have it set to that a user can add a node. So once the node has ben added how do I let them rename it as it is being added and without being a prompt or inputbox? So lets say I cam clicked on a parent and they click add node, it adds it to parent but I have it so it is default "New" but I want them to edit it as it is added. I think it will be along the same lines as clicking on one and rename but I have to start some place.
I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

Why this line doesn't change the value of my datetimepicker using me.gatepassbindingsource.addnew():
Me.GatepassDataSet.gpheader.gpdateColumn.DefaultValue = Now()
Implementing BindingNavigatorAddNewItem executes above line correctly. I don't want this because the bindingnavigator items are active. Coding me.gatepassbindingsource.addnew(), I can make my bindingnavigator items inactive/disabled while adding record.
I've got a page which has 5 images on, 5 FileUpload controls, 5 buttons and in the code behind 5 on click events. The page shows the images and lets users change each individual image if they'd like and it's all working well....except. When the upload is done and the new image has been uploaded to the ftp server, how do I then re-display the same page the user has just used, but this time with the new image image in place of the old? Do I need to call an instance of the page_load event again?

I have an editable datagridview that's been databound with dataadapter and datatable, and a normal button on a form. When i edit the dgv's cells and click the save button it fires the datagridview_cellvalidating event and if the cell validation is correct it updates and saves the current record to the datasource. Also, before save it commits change in any cell under editing. But when I use a toolstripbutton to do the same work, though it saves the dgv records but doesn't update the current change i.e. it saves the old records that are being fetched when the dgv was populated first during form load. Also, clicking the toolstripbutton doesn't fire datagridview_cellvalidating, datagridview_rowvalidating etc events. What it seems to be is it's not committing the change in any cell under editing. [Code]
Why isn't it happening and how can I make it work? how can I fire datagridview_ cellvalidating, datagridview_rowvalidating and other events; and commit cell value change by clicking toolstripbutton.

View 6 RepliesHi, I have a project that works with a database. It groups al my films per category. I use this code to group everything by category. The categories are chosen in the combobox cboCateogorie.
Private Sub cboCategorie_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboCategorie.SelectedIndexChanged
If Not cboCategorie.SelectedValue Is Nothing Then
cboCategorie.DataBindings.Clear()
cboCategorie.DataBindings.Add(New Binding("Text", objDtsMuziekcollectie.tblCategorieen, "CategorieID"))
Dim dtvDVDInhoud As DataView
dtvDVDInhoud = objDtsMuziekcollectie.tblDVDInhoud.DefaultView
dtvDVDInhoud.RowFilter = "CategorieID = " & cboCategorie.SelectedValue.ToString
dtvDVDInhoud.Sort = "DvdID ASC"
objTblDVDInhoudBindingSource.DataSource = dtvDVDInhoud
Me.objTblDVDInhoudBindingSource.MoveFirst()
End If
End Sub
Now I've made a textbox and a button which I can search with. But I want that my category in the combobox changes when a film is selected with that search. Now I already have this code to search with a joker sign.
Private Sub btnZoek_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnZoek.Click
Dim dtvZoeken As DataView
dtvZoeken = objDtsMuziekcollectie.tblDVDInhoud.DefaultView

objTblDVDInhoudBindingSource.DataSource = dtvZoeken
dtvZoeken.RowFilter = "Titel like '" & txtZoekveld.Text & "*'"
End Sub
Ok, so what I want is the opposite off what I do when I select a category in a combobox. Now I actually select a film and this film also has an ID, namely DvdID and with that I want that the combobox shows the category where the film belongs to.

Label1.text += textbox1.text doesn't work, say they is 0 in label1 and i enter 1 in the textbox1 it adds it to the label like this
0111111111111
But i need it like add up whatever is in textbox to whatever is in label1 This works
Label1.text += 1 but thats not what i need I got this to work once before, but i cant remember because its been long time ago.
I have a WinForms app built with VB.Net in VS 2010, and I'm scratching my head over the following issue.I have a form with a combobox which gets bound to a datasource when the form is loaded:
With Me.cboCompany
.DataBindings.Clear()
.DataSource = Me.m_dsBidResults.Tables("Company")
.ValueMember = "company_id"
[code].....
This seems to work fine, as long as the user doesn't switch focus to some other control and then go back to the combobox. After switching focus, if the user then changes the combobox selection to the first item in the dropdown list (SelectedIndex = 0), the SelectionChangeCommitted event fires, but the SelectedValue remains set to the previously selected value. I've verified this by adding a message box in the above event handler, displaying SelectedIndex and SelectedValue side-by-side.
'add this to SelectionChangeCommitted event handler MsgBox(String.Format("Selected Index: {0}, Selected Value: {1}", cboCompany.SelectedIndex, cboCompany.SelectedValue))
This does NOT happen if the user changes SelectedIndex to anything other than 0; everything behaves as expected. I've verified that the table I'm binding to contains unique values for company_id and company_name.Do I need to use some other event to verify that the SelectedValue has actually changed?
It seems like when there is only one row at the data grid view with a data source pointing to a data table, it's row state for the data table doesn't change when editing. It remained "unchanged" reguardless to how many columns I had entered. However,after editing, when you click on a different row or click on any of the column headers to change their sorting, the row's state from the data table then gets changed to "modified". I'm not sure why the data table's row states gets changed only when you do those things instead of finishing editing itself. Couldn't the data grid view be able to change the data table's row states when you finished editing a cell?
View 5 RepliesI have my company's website (Visual Studio / vb / asp.net 4.0) localized in 9 different languages, and they all work great. When you're on, for instance, about.aspx, and you switch to Russian or Swedish, it stays on about.aspx and doesn't add a query-string to the end of the URL; it just changes the page's text to that language. Will the major SEs like Google, Yahoo, etc., consider this duplicate content for SEO purposes and if so, what should I do?

I have a VS2005 utility that I'm working on that has an Access 2003 backend. A couple of days ago, my boss asked that I change one field in two tables from TEXT to MEMO, to allow more information to be put in. In doing some final pre-deployment testing, I find when I hit my button to pull up the list of tickets, I get the error
"System.Data.ConstraintException was unhandled
Message="Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.""
The datagrid is based on a query I have in the database. The query runs fine, and when I go through the XSD and go into Query Builder, the QB is also returning data. I have made the various changes to the utlity as suggested by Microsoft, but no luck. When I put the two columns back to TEXT, the Grid works fine.
How the heck do I set it up so that the grid will recognise the new data format? The number of characters for the individual columns is set to 37,627 (I believe, it's whatever the default is). I only have 200 characters in my test data. I need to rebuild the whole dataset - this deployment has to be done by the end of the day tomorrow and I have a whole pile of other stuff left to do.
