yes i agree with you... "Windows already has a lock screen built into it that will always be more secure that your app." but i want a program that acts almost the same but allows me to run programs . windows 7 lock on my PC will not allow me to run some of my programs while its in use. im goal is to make an app to allow me to run program and act in place of windows lock.
Unless your descriuption is missing a crucial little detail, the Lock Screen doesn't prevent your apps from running at all. You can run anything you want, then lock Windows whenever you want. The only exception to that would be some games.
The app im working on now has a timer to keep it ontop. it is password enabled to both lock and unlock it so random kids cant lock or unlock the PC without the password. i made the app so it can not be shutdown with the ALT+F4 keys, it is borderless, and FILLS the whole screen.
If it's used to protect your environment against kids, then by all means, simply use the account-control that comes with Windows. It provides in a safe password-storage and a safe environment.
These type of questions often benefit from additional background-information, such as the version of Windows that you're targetting. If you're merely looking for your own environment then open your own desktop[^].
That depends on what you mean by "get picture file size when loaded into application".
A Bitmap object will always represent an image in memory as 32-bits per pixel (R, G, B, A). Images on disk can be of varyious formats and compressions, so there is no relationship at all between the image size in memory and the file size of the image on disk.
hey thank you for that code, but i've just figured out that your suggestion works only for standard picturebox.
however, i'm using devexpress picture edit control.
this control didn't support location.
but really, thank you very much for helping.
actually i'm asking why when i convert an image into byte array
and get the length, i gain byte size of the image,
but the size always bigger than the real image 10-50KB.
you are right about compression dave, thank you.
I plugged in a form a datapicker, but I'm having difficulty viewing the correct date when I fetch the same from a mysql table.
I manage the double-click on a row in a datagrid to retrieve the record data when editing a record in a form.
If the date my datapicker (textdatanascita) is set to the value of the table.
FormRegistrazioneUtente.TextDatanascita.Value = Me.DataGridView1.Rows.Item (e.RowIndex). Cells ("ut_datanascita"). Value
As evidence of this fact I put a msgbox to check the accuracy of the data, and in fact everything is ok. The data obtained is as expected.
But when I open the form all the data in various textboxs are the expected ones, while only datapicker still shows the current date.
Someone would be so kind as to tell me where wrong?
It isn't very clear what you're having a problem with. Are you saying that you're trying to retrieve records from the database using the date in the DatePicker control?
Or, are you saying that the date you get from the database isn't being bound to the DatePicker control properly?? If so, what does you're code look like that does the binding to the DatePicker? Are you binding to the DatePicker's SelectedDate property?? You should be!
I am working on app in vb 2008 and have following situation:
I have one form with datagridview binded to access table with dataset, bindingsource, tableadapter and tablemanager. User cannot change, delete or add records in datagridview.
On same form I have two buttons for editing and adding new records
When user clicks on "edit" button another form is opened and on this form detailed information is displayed (based on row selected in datagridview) so user can edit and save data. On second form there are several txt boxes binded to same table through another dataset filtered on current record with following code: frmPD.TblPartnersBindingSource.Filter = "CompanyID =" & TblPartnersDataGridView.CurrentRow.Cells(0).Value.ToString
My quiestions are:
1. Is this correct way to open "details" form (using filter property of bindingsource)
2. How to use same "details" form to add new record.
