Re: Transparent bitmap 26-Mar-02 4:18 26-Mar-02 4:18  Thanks James Yes, it's a nice alternative to was I was doing (using ImageList class). But I forgot to explain that I was using PictureBox control not device context. I still wonder if I could use two PictureBox controls, one transparent over the other. Thanks again Jerzy inherited forms resizing issue 25-Mar-02 4:32 25-Mar-02 4:32  ive got an inherited form base class (BannerDialog) that has a banner on top and buttons on the bottom. the banner and buttons are anchored to the form using the ide'd design window. my problem is that on the inherited form (MyDialog : BannerDialog) the banner and buttons dont move when MyDialog resizes. Re: inherited forms resizing issue 25-Mar-02 5:09 25-Mar-02 5:09  Did you call base.OnResize() ? Jerzy Still Need HELP! 25-Mar-02 5:54 25-Mar-02 5:54  im not certain what you mean. i currently do not call base.OnResize(). If i do, do i override BaseClass.Resize()? and if so, how do i resize the base class's window size? where do i get the dimentions? *** added *** if i delete the inherited form's "this.ClientSize = new ..." in the Initialize component, and do nothing else, it seems to work. the form snaps to the inherited window's size and anchors properly. but i dont understand why. And the winner is... 26-Mar-02 4:39 26-Mar-02 4:39  well, after toiling around the msdn i found a little blurb stating that controls on inherited forms that have anchor properties MUST be set to PROTECTED and not PRIVATE.. exposing controls is the absolute wrong way to write inherited forms (im no architect, but im pretty sure that breaks the model). -- unless there's a way to block the user from directly accessing the PROTECTED control aside from setting it's anchor. so the solution..? in base.Resize() i simply made the layout recalculations myself. years of vb experience pays off.

How I can generate a 5-digit ID in C# gicio25-Mar-02 2:49 gicio 25-Mar-02 2:49  any idea?? big thx! Pawel Re: How I can generate a 5-digit ID in C# Kannan Kalyanaraman25-Mar-02 4:45 Kannan Kalyanaraman 25-Mar-02 4:45  generate a random no , convert it to string, take out the first five characters and then convert it back to no. You can look at how to generate random nos in the System.Security.Cryptography namespace. There is a class for random no generation. Hope this helps. Cheers Kannan Re: How I can generate a 5-digit ID in C# gicio25-Mar-02 7:17 gicio 25-Mar-02 7:17  cool!! and thx.. but can you give me a code sample how i can generate a #? becouse i can´t find any code sample in the msdn. thx Re: How I can generate a 5-digit ID in C# Neil Van Note27-Mar-02 18:29 Neil Van Note 27-Mar-02 18:29  I am still pretty new to C#, but on a hunch I would check out the Random class...

Rüpel25-Mar-02 1:34 Rüpel 25-Mar-02 1:34  when i choose project-new-c#-windows-app i only get one form and the corresponding class. but when you look at the c#-scribble example in the msdn-lib, and especially the readme.txt-file there, you see that some wizzard created a "mainframe"- a "doc"- and a "view"-class. like in good old mfc-times so where is that wizzard? does anyone know? of course i could just take the scribble-code and change it to fit my needs, but i want to know the ide i'm working with. so where is that thing hiding? i'm working with vs.net thx in advance :wq Re: howto create doc/view c#-apps?

As an example, I'd love to be able to use an image as the actual tab, wich could give me the flexibility to create any color, shape and form on the tabs.... Please, if you have any tips on how to do this, let me know.... Re: Any way to create a better looking TabControl? 25-Mar-02 4:20 25-Mar-02 4:20  check out these guys. http://www.dotnetmagic.com/TabControl.html . just re-write what you want... its a bit of work to factor out the other two parts of their library, but its worth it. solid code... light documentation. Replace parts of an object in an ArrayList.But how ??? gicio24-Mar-02 23:18 gicio 24-Mar-02 23:18  hi! I have a problem: here I read the data from the ArrayList into the ListView with a checkBox (displayCarListView.CheckBoxes = true; )public void ShowCar(ListView objectDisplayCarListView){ListView displayCarListView;displayCarListView = objectDisplayCarListView;foreach (Car car in carArrayList){MessageBox.Show(Convert.ToString(carArrayList.IndexOf(car)));int carIndex = carArrayList.IndexOf(car);ListViewItem newItem = newListViewItem(((Car)carArrayList[carIndex]).Manufacturer);newItem.SubItems.Add(((Car)carArrayList[carIndex]).Model );displayCarListView.Items.Add(newItem);}} now I would take this data that was checked in the ListView and put it in an other GUI with TextBoxes (it should the index of the car in the ArrayList must transfer also to the other GUI (but I don´t really know how! )) I try it so: (but without the index....thats work 100% .... but I need the Index of the car...) public void ChangeCar(ListView objectDisplayCarListView){ListView displayCarListView;displayCarListView = objectDisplayCarListView;Car currentCar = new Car();if (displayCarListView.CheckedItems[0].Checked){ChangeCarNow currentChangeCarNow = new ChangeCarNow(this);currentChangeCarNow.manufactoreTextBox.Text =displayCarListView.CheckedItems[0].Text;currentChangeCarNow.modelTextBox.Text =displayCarListView.CheckedItems[0].SubItems[1].Text;//here the other GUI is show......with the datacurrentChangeCarNow.Show();}} in the GUI currentChangeCarNow(ChangeCarNow) it should be change the data of the car. the changes data of the car I must put back exactly in the same place where I take it out. that's why I need the index of the car have someone an idea how i can do this? big thx!!
