Access key for a user control jantie7828-Dec-02 3:57 jantie78 28-Dec-02 3:57  Hi all, I am creating a custom user control (inherited from the UserControl class), and I would like to mimic the behaviour of the standard Button control. When you set the Text property of the Button to '&Close', the button shows: 'Close'. When you press ALT+C when the form is active, the button will receive a click event. Does anyone has an idea about how to accomplish this?

Fire the click event of the button from the the OnKeyPress/Down (cant remember which one now ) event of the form after checking the pressed keys modifier and which key was pressed. Hope this helps WebBoxes - Yet another collapsable control, but it relies on a "graphics server" for dynamic pretty rounded corners, cool arrows and unlimited font support. Re: Access key for a user control Jan Tielens28-Dec-02 5:28 Jan Tielens 28-Dec-02 5:28  Thanx for your reply. But I want to have all the needed code in my new User Control, just like the standard button. When you place a standard button on a form, and set the the text to '&Close', the click event will be called whenever the alt+c keys are pressed (and the form has focus). Even if the current focus is in a textbox on that form for example. Any idea's?? Jan Re: Access key for a user control leppie28-Dec-02 6:41 leppie 28-Dec-02 6:41  UserControl has a ParentForm property that you can use to access the form.

Re: Access key for a user control Jan Tielens28-Dec-02 6:42 Jan Tielens 28-Dec-02 6:42  (Thx again) But can the form catch all the keypresses, even if the keypreview property is set to false??

You also have a domain option. What you are trying to send to, is a subnet mask and that wont work. I just tested 255.255.255.255 (broadcast address) and I received a msg on my local PC, unfortunately I only have 1 Win pc on the network Anyways, hope this helps WebBoxes - Yet another collapsable control, but it relies on a "graphics server" for dynamic pretty rounded corners, cool arrows and unlimited font support.

Smitha Nishant27-Dec-02 18:21 Smitha Nishant 27-Dec-02 18:21  Hi all, I am developing this image edit application. I want to provide undo and redo of actions - rotate, scale and crop. Any suggestions on what will be the best way to implement this ? I am more interested on the undo implementation after a crop. Keeping a backup image in memory can be one option. But when it comes to undo-ing multiple actions, it might become inefficient Smitha Whenever I see an old lady slip and fall on a wet sidewalk, my first instinct is to laugh. But then I think, what if I was an ant, and she fell on me. Then it wouldn't seem quite so funny. Re: Whats best method to implement undo redo ? James T. Johnson27-Dec-02 19:14 James T.

But when it comes to undo-ing multiple actions, it might become inefficient I would keep two images in memory, the original and the current version. Then each time you perform an operation on it create and store some data that tells what that operation was. When you undo something, take the last operation off the stack of operations, then starting with the original image perform each operation. You may want to limit the number of operations allowed to be undone, or come up with some other variant of that (every 8-32 operations create a new 'starting' image, etc).

I recently compiled a product using release instead of debug and tried to run it on a machine without VS.net. It gives me some errors... for some reason the exe didn't include some of the .dll's needed for the actual .exe to run. If someone could point lme in the right direction that would be awesome. Thanks... Re: Compilation for Release Anonymous27-Dec-02 17:43 Anonymous 27-Dec-02 17:43  Hey nascokeg! Do you have .net runtime over the target machine? Re: Compilation for Release gekoscan27-Dec-02 18:30 gekoscan 27-Dec-02 18:30  Hey thanks for your reply... hmm.. the .net runtime? I have windows XP on the machine but I am not sure what you are refering to? Could you help me out? LOL you are probably thinking o man what this guy must be retarded. Thanks very much. Re: Compilation for Release Brian Olej27-Dec-02 19:09 Brian Olej 27-Dec-02 19:09  Well, let me start by saying you cannot run .NET programs on computers that do not have the .NET runtime, it is around 23mb and can be downloaded from microsofts website[^] and it contains all the .dlls required to run .NET apps. I hope this helps you... Why waste time learning when ignorance in instantaneous -Hobbes Using Font in C# gekoscan27-Dec-02 13:19 gekoscan 27-Dec-02 13:19  I am attempting to place a font over some pictureboxes on my form. But for some reason.. In my OnPaint function: Font font = new Font("Trebuchet MS", 24,FontStyle.Bold); Graphics g = Graphics.FromHwnd(this.Handle); g.DrawString("Text on the Screen", font, new SolidBrush(Color.White),0,0); This paints behind the picture boxes on my form.. Can someone tell me how to set the zorder or something... i find it kind of weird... But i have an idea that it has to do with the handle I am grabbing.. Thanks Everyone...

I'm of course referring to inserts with an apostrophe (single quote) in them. I have some ideas on how to solve it - either to use a Replace type method or to write a stored procedure (I'm using Access, so it should be one of those Access Query things). Is there a standard approach which is best? *->>Always working on my game, teach me *->>something new. cout << "dav1d\n"; Re: The O'Mally problem Nick Parker27-Dec-02 9:01 Nick Parker 27-Dec-02 9:01  afronaut wrote: Is there a standard approach which is best? I will assume you are using C# since you are posting in this forum, however I always typically write a little function to handle this as it can be used throughout an application. Another Access Query really isn't necessary for something like this. Something like the following works well in C#: string CleanSql(string s) { return s.Replace("'", "''"); } Nick Parker You see the Standards change. - Fellow co-worker Re: The O'Mally problem Philip Painter29-Dec-02 11:55 Philip Painter 29-Dec-02 11:55  We use stored procedures and set up the parameters with, for example "O'Mally", just as they are and it all works swimmingly.

When I navigate to a web page ex:www.hotmail.com and change the focus to another application on the desktop using ALT + TAB and come back to my application again, the web page in the web browser control would have lost focus. I am using using the following command to navigate object o=null; axWebBrowser1.Navigate( textBox1.Text,ref o, ref o, ref o, ref o); Any idea how to get back the focus Thanks Kiran going from vs.net to commandline grv57526-Dec-02 22:03 grv575 26-Dec-02 22:03  Compiled an assembly with visual studio and am now trying to get it to compile on a box with just the sdk and command-line tools. It's missing the mshtml reference which I think is a com object. Trying to get a type library from the winnt\system32 dll file fails. How would I compile it with just the sdk then? Re: going from vs.net to commandline Stephane Rodriguez.27-Dec-02 8:08 Stephane Rodriguez. 27-Dec-02 8:08  First of all, the mshtml.dll file you refer to is not the native dll we are used to with C/C++, but the interop assembly, which is located in <program files>\Microsoft.NET\Primary Interop Assemblies\Microsoft.mshtml.dll The way to compile your code is to reference this assembly with the /reference option.

Programatically displaying dropdown menus from toolbars Arun Bhalla26-Dec-02 16:08 Arun Bhalla 26-Dec-02 16:08  Hi, I'd like to programatically display a dropdown menu from a toolbar. To be specific, I'm developing an Explorer bar, and I'd like to give it a menu. As far as I know, the only way to do that is to use a toolbar. So I have a couple buttons (File, Edit), and they both have dropdown Menus. When a user clicks on the File button, I want it to popup the File dropdown menu, just as it might if the user clicked on the dropdown arrow. I don't see a natural way to do it within the API yet. I tried using Show(), but the only problem is that I'd need to calculate the correct location for the dropdown menu to popup. Any better solutions? Thanks, Arun
