Handling DPI Changes In Windows Form?
Feb 16, 2010I am developing a windows based application in VB 2005, the main form of the application is of fixed border style (i.e. user cannot resize the form), but in certain cases I am resizing my form through code. Intially the form has a fixed height i.e. 350 for normal height and 400 for extended height. But in this case the problem could not be solved effectively as the user can have different DPI setting e.g. 120, 144, 192 etc.The logic I implemented is to divide my form (vertically) into 3 parts

Handling New Internet Windows?
Jul 15, 2009I have a form within which has a webbrowser control. The site i view in the webbrowser control requires me to log in so i have made a one click login button which when clicked logs me in automatically. When i'm in the backend of the website, if i click on a certain button it pops up a new window that i need to make a selection from. But when this window pops up it asks me to log in again?Is it possible to catch all pop up windows so they are loaded in another form which also includes this 1 click log in to save the hassel of logging in manually again?

COM Object Handling Differences Between 2008 Express And VB 2008?
Jul 15, 2009I recently created a very simple project in VB express 2008 to interface with a COM object from an external vendor. I then downloaded the VS2008 90 day trial and found that the identical code in a VS2008 project results in a COMException error "Object is out of scope". Is anyone aware of any differences in how the two packages handle COM object interfaces as I have run out of ideas. Both projects have identical code and all the references are the same. The CreateObject() method correctly creates the object, but any attempt to access methods inside the COM object result in that error. I can even open the VB 2008 Express project inside VS and it still generates the same error.
Here is the code - the vendor dll in question is from Siebel v8.0.0, you'll notice that I have commented out most of the code that comes after the error. Creating a watch in the debugger on the siebApp variable sees it correctly created as {System.__ComObject}type SiebelHTMLApplication. I first tried this by creating the Property Service for variable siebSvcs, but after I started experiencing the COMExceptions, I reverted to using the most basic method inside the COM object I was creating.

VS 2008 Handling Strings?
Apr 12, 2010I once again feel so angry about VB .NET . Here's what ruined my day :Lets say we have have a string variable :
Dim Var1 As String = "blablabla"
If we want to replace something within it , we can use the Replace function :
Dim Var2 As String = Replace(Var1,"a","o")
This works great . My problem appears when I want to replace the " character (double quote) . Thus , when using :Dim Var2 As String = Replace(Var1,"""","o")it will return an error .Of course you may wonder why I care to replace the " character . You see this string variable receives its value from a text box . Thus , if the user uses the " character , I want to replace it with two ' characters (single quote) . Is this replacement possible in .NET
VS 2008 GDI And Paint Event Handling?
Aug 26, 2009From jmchillihiney's most excellent code bank sumission on Drawing:Quote:The way GDI+ works, controls get repainted on screen over and over again, sometimes many times in quick succession. On each of these occasions the control's Paint event is raised. You need to use the Paint event of the control to perform your own drawing or else, the next time the control is repainted, your drawing will just disappear as the control paints over it.
When you're creating a custom control you should override the OnPaint method and perform your drawing there. When you're designing a form or user control and you want to add custom drawing to a child control you handle that control's Paint event, then perform your drawing in the event handler.
You may have seen, or heard people talk about, controls flickering on screen. That's caused by repainting large areas of the control repeatedly and happens because painting on screen is actually quite a slow process. As such, you should try to do as little of it as possible.So, I am attempting to draw part of a custom control. I have placed a SplitContainer on a UserControl, and oriented it vertically. I then shrunk to top panel to 15 pixels in height. I have two Methods which each draw a different type of Path + fill into the panel, and then draw a border around it (One is a gradient fill, and the other is just a plain color). The idea is that when the user clicks on this panel, it switches from one to the other (a "Selected State" and "Not-Selected" state).
I have also created an icon which looks like the +/- widget on a treeview (or more specifically, on the vs2008 Toolbox, which is essentially what I am trying to emulate here . . .) which toggles as the control is selected/unselected. Not that ultimately, the selected state will change when the user selects OTHER controls, but the Expand/Collapse gizmo will toggle when the user clicks on the panel in question.
Again, check out the vs2008 toolbox. The Group "headers" are what I am after here. Believe it or not, all of this now WORKS (gee me, look what I did!) EXCEPT the initialization. If I "Handle" the paint event of the SplitCOntainer.Panel1 object in any way which prevents the flickering jmc alludes to above, any redrawing required by either initialization OR hiding/unhiding of the host form is prevented. And it seems like the SplitContainer panel is constantly redraing (probably checking to see if the splitter has been moved).
I can post some code, but it is a little confusing, since I am dealing with some semi-complex interaction here. Also, It is not necssecarily structured well ()yet). AFTER I figured out the drawing bits, THEN I was going to try to do some refactoring and restructuring. Code Follows in next post.

Apr 28, 2009I have the following code in a class of mine. The purpose of this class is to get the balance from a web server. Just in case something goes wrong with getting the balance. I will handle a exception. However, all this is easy to do. But I am left wondering what do I return in my catch statement.
Most of the examples I looked at just write to the console using:
Console.WriteLine(ex.Message);
That is all very well. But in a real application what do most developers do?
My function at the moment returns void. And I am just wondering what else I would return if the webclient is busy?

View 6 RepliesVS 2008 Exception Handling In User Classes
Apr 27, 2009I have to get the balance from the web server. Once that is done it will call back into my main app with the result.However, sometime the web server fails for some unknown reason. Could be high volume of traffic or something else. However, I haven't implemented any exception handling in my class. As the app that uses this handles the exception. However, the client has confirmed that when the web server does fail it displays a unhandled exception dialog box. Then they have to click continue to keep using my application. So below I am not sure if I should implement the exception handling in my class.[code]

In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?
View 2 RepliesVS 2008 Handling Exceptions In Custom Control Library
Oct 21, 2009So I've made this control that inherits from the treeview control and basically loads objects from active directory into a treeview (url...).All working fine, but as this is the first custom control I have made that I have intended for other people to use, I'm not quite sure how I should approach error handling.I mean, obviously I shouldnt do something like show any exceptions in a messagebox because that might not be what the person that is using the control wants to happen. So do I just write out exception messages to the debug window? Do I swallow exceptions (guessing not)? Do I just totally ignore them so that they are thrown in the user's project?
View 4 RepliesVS 2008 Handling Exceptions In Referenced Class Libraries
Jun 8, 2010i created a Class library (.dll) and loaded it as reference into a main project. In the code for the class i've handled exceptions using try..catch subs, however when debugging the main project exceptions that are handled in the DLL still get thrown! (the class ".vb" file gets loaded into the debugger and the line of the exception shows up)
Up till now i've found it useful that when an unhandled error occurs in the imported reference, it shows up in the main project with tracing back to the referenced class. But i dont want the exceptions that are handled in the reference class to be thrown when debugging the main project!
As you can see the exception thrown was handled with try...catch this class exception.vb belongs to the project that created the class library (.DLL that i referenced). i didnt even load the project that built the reference so it amazes me that it could find the coding class to begin with.
