Re: Form layout at runtime differs from design Luc Pattyn19-Oct-09 3:17 Luc Pattyn 19-Oct-09 3:17  When Dave said EnableVisualStyles is what triggers the theme-based renderer, doesn't that suggest you to try and run your code without that statement, and see what gives? Luc Pattyn I only read code that is properly indented, and rendered in a non-proportional font; hint: use PRE tags in forum messages Local announcement (Antwerp region): Lange Wapper? 59.24% waren verstandig genoeg om NEEN te stemmen; bye bye viaduct. Re: Form layout at runtime differs from design Member 332970019-Oct-09 3:44 Member 3329700 19-Oct-09 3:44  Ok, sorry, should have mentioned that I tried that already. But when I remove the EnableVisualStyles statement, the whole XP-style disappears (of course ). It seems to me that the EnableVisualStyles statement is correct, as I want to use the systems theme. The form is during run-time and in the form designer almost identical (i.e. using XP style), the only little difference is that the text on labels and buttons is moved about 1 or 2 pixels, which results in some cases in two lines of text in stead of one, as the text doesn't fit on one line anymore. Of course I could make the labels and buttons a few pixels larger. It's just that I don't like the fact that there is a differce between the form in the designer and in run-time. Someting must cause the difference... Furthermore, when I start the form by setting the MainForm as Startup form in the project properties, and enabling XP visual styles, the form shows correctly. So any help / suggenstions are welcome! Re: Form layout at runtime differs from design Luc Pattyn19-Oct-09 3:57 Luc Pattyn 19-Oct-09 3:57  OK, I don't know the solution; I tend to make my controls slightly wider to avoid such issues. BTW: what will happen if you ever need to internationalize your Form?

Re: Form layout at runtime differs from design Henry Minute19-Oct-09 5:55 Henry Minute 19-Oct-09 5:55  There is a relatively well known problem in this context, caused by the differences in the way that GDI and GDI+ do their rendering which may explain your problem. This[^] explains it and has a demo project. There is a better explanation that I cannot locate at the moment. Some time ago I posted it on CP for another member. At that time I found it by Googling gdi v gdi+, which is where I got the link above. If you have more patience than I, give it a try. Henry Minute Do not read medical books!

If I set the buttons and labels 'FlatStyle' property to 'Sytem' in stead of 'Standard', the form shows up correctly in run-time. However, I'm still wondering why there is a difference between setting EnableVisualStyles in code (showing the text different then in the designer) and setting 'Enable XP Visual styles' in the project properties (showing the text the same as in the designer)... Beyound understanding PING problem optimusprime2k18-Oct-09 8:05 optimusprime2k 18-Oct-09 8:05  hi friends, i am facing a problem like we i ping a node i got following response CAREFULLY see PING STATS Pinging 10.10.34.45 with 32 bytes of data: Destination Host Unreachable Destination Host Unreachable Destination Host Unreachable Destination Host Unreachable Ping statistics for 10.10.34.45: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), if node is not reachable how i am getting received packet.... and 0% loss plz help me solve this.. Thanx for your valuable help optimus Re: Beyound understanding PING problem Dave Kreskowiak18-Oct-09 10:48 Dave Kreskowiak 18-Oct-09 10:48  The received packet that it's talking about is the one coming back from the router explaining that there is no route to the destination network. No, it's not the original ping packet, but a valid pakcet did come back, so, yes, it's a "successful" receipt. If not packet had come back at all, that's the "Lost" packet.

Re: decrypt the dataset Dave Kreskowiak15-Oct-09 1:28 Dave Kreskowiak 15-Oct-09 1:28  You call converting a string to Base64 encrypted? That's not encrypted at all. The code is correct as far as I can see. You're going to have to double-check what you're passing into each method and what you're getting back.

You've already got the code that does the job. For some reason, you've either not following what youre passing into the encryption/decryption methods or you're not storing or retrieving the data from the database properly.

Readonly ComboBox - Please give help? veeramani narayanasamy12-Oct-09 19:54 veeramani narayanasamy 12-Oct-09 19:54  I need Readonly ComboBox in vb.net windows application, for this requirement i used to use textbox & combobox together in the same place. TextBox Properties ReadOnly=True TabStop=False ComboBox Properties AutoCompleteMode=SuggestAppend AutoCompleteSource=ListItems TabStop=True in ADD/EDIT events set ComboBox Enabled=True, if the event is done ComboBox Enabled=False this is my code Private Sub ComboBox1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.GotFocus TextBox1.Visible = False End Sub Private Sub ComboBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox1.LostFocus TextBox1.Visible = True End Sub Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged TextBox1.Text = ComboBox1.SelectedItem().ToString End Sub in design TextBox on top of the ComboBox, can see only the ComboBox Button. Please give me any simple solution for this.... N.K.Veeramani Software Engineer InteriTech SDN. BHD., Malaysia Re: Readonly ComboBox - Please give help? Mycroft Holmes12-Oct-09 20:45 Mycroft Holmes 12-Oct-09 20:45  Your logic, at a form level, seems wrong. When you display the dialog you should know if CRUD is required at which point you display a combo so the user can edit the data. If the user is opening the form as RO then either disable the combo or display a textbox with the required value. I cheat, if the user does not have CRUD rights on the form/data I make the save button invisible/disabled. The user can do what they like, just can't save the results. Re: Readonly ComboBox - Please give help? veeramani narayanasamy12-Oct-09 21:45 veeramani narayanasamy 12-Oct-09 21:45  thanks for the reply. i will tell why i need like this if i set ComboBox enabled=false the user can't the value clearly. thats-why i needed like that so how to solve this N.K.Veeramani Software Engineer InteriTech SDN. BHD., Malaysia Re: Readonly ComboBox - Please give help? Mycroft Holmes12-Oct-09 22:18 Mycroft Holmes 12-Oct-09 22:18  My point is why are you making the combo readonly. Simply disable the save button. If you insist on readonly then have a textbox on display when the form is in the view only mode and swap for a combo box on the add/edit event. If the act of entering the combobox changes the state of the form to edit mode then why are you bothering to have it readonly.
