Image Doesn't Change After A New One's Been Updated
Jan 3, 2010
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'm fairly new to ASP.NET and of course happened to stumble some strange problem. problem is very popular, but none of the replies I found worked for me.
[Code]...
And the image doesn't change. It doesn't even fire up the showphoto.aspx code.The property is changed (because next time i step into it, it's changed), but showphoto is never fired.I'm aware of image caching issues, but I can't get even one image, not mentioning have it changed.For sure there's a very simple explanation, but I'm fighting with this for 2 days now to no avail.

I have an initialize function that loads data into my textbox NameTextBox, and then I add an "s" to the name. I then click the Save button that executes SaveButton_Click when debugging the value for NameTextBox.Text is still the original string (FirstName) and not (FirstNames).
Page_Load(sender, e)
Info = GetMyInfo()
Initialize()

I use two DataGridView“s to manage my database. DataGridView2 is filled with data from a table depending on what value you select in DataGridView1. I also have a search-function so I can search for specific values in DataGridView2. In pictures below I have searched for GroupID = 1 I can also copy all the values in the DataGridView2 into the database if I want to. The data often states what kind of values to use to use during a test of a machine. Sometimes I want to copy all the parameters for one machine and use on another machine. I have added a column that is used to write down notes about the data in the table. This is the only column not copied (except the primary key column) when I press copy. Its called Tableinfo
I can then search the active table for all rows where that column is empty. When I have changed the values or just confirmed that everything is alright I have a button called "Save" that fills that column with the string "Saved" so those rows doesn“t appear next time.
Here is where the problem occurs. When I press the save button I can see that the whole column is filled with the correct value. But when i press update the first row doesnt get updated. No matter how many rows there is in the DataGridView.
If I fill in all the rows manually it works. If I press the save button and then click in the cell of the first row where is says "Saved" and then update it gets updated correctly.

This program asks the user for a number and then an amount to multiply it with and that amount should be added to the initial number. I need to loop because I am trying to display what the amount would be each day for a certain amount of days but in this loop its only calculating for the total .how to get the variables to change value to the updated day. I understand that its just keeping the same value in the variables I just need a push on how to get it to update the values through each loop.

Ok, 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.

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?

How do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.

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.

My vb app uses an icon which is 128x128, which looks fine on the desktop. But when viewed in a folder with View set to Extra Large Icons its size doesn't change - it is too small (smaller than 128x128). Any ideas how I can rectify this?

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.

I have a field on my form for Check Number if a bill was paid by check, if not it should be blank. When I run the query in Access it returns the right records.the query loads all current customers, 99 out of a possible 107, when I navigate through the records as soon as I hit one where a Check was used, the Check Number field stays filled in for all records displayed after.

I have a form that asks the user for certain search criteria. Based on this it goes and searches Active Directory for computer accounts. Whilst this search is happening I want the cursor to change to the hourglass but I've tried
Application.WaitCursor=true
Me.Cursor=Cursors.WaitCursor
me.UseWaitCursor=True
Nothing works. The cursor stays firmly as the default cursor.This is the code that calls the form
Dim inputform As New MachineSearchInputForm
If inputform.ShowDialog = System.Windows.Forms.DialogResult.OK Then
Dim PropertiesToLoad As String() = New String() {"name", "distinguishedname", "objectclass"}

Hi, 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
dtvZoeken.Sort = "DvdID"
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.
