Accessing A Dialog Box's Handle And Automatically Manipulating The User Interface

Jul 17, 2009

I have some VB code which makes use of a COM api and results in a certain dialog box popping up on the screen. My program is a console application, that needs to run in a batch file, but I haven't found any other way to do things other than finding a way to automatically manipulate the dialog box. Here is the api call (omitting setup code) that results in the dialog popping up:

Interface And Graphics :: Use A Graphical User Interface That Contains A Drag And Drop Form?

Oct 19, 2008

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.

Parallel Extensions Automatically Handle Single And Multicore Environments?

Apr 8, 2009

Will LINQ's parallel extensions automatically detect the number of cores and utilize them all? Conversely, if the code is run on a single core machine, will it still work or do I have to detect the number of cores and tell PLINQ how many to run across? I don't have access to any single core machines to test my code on so I can't even test this for myself and I haven't been able to find any useful info elsewhere...

Also, while it might at first seem obvious when to use parallelism, are there any rules of thumb regarding where it should and as importantly should not be used? I don't necessarily program in a specific environment. I tend to divide my time somewhat equally (depending on project) between web, client/server apps, windows apps, windows service and console utilities depending on the task at hand.

Interface And Graphics :: Sharing Violation While Accessing Bmp File

Mar 11, 2009

I was writing a small test to verify loading and editing a bmp file with a process and MS Paint. If I load the file image into a picturebox before I run the process MS Paint reports a Sharing violation on the file during save. If I Leave the Picturebox empty MS paint allows the file to be saved.

Below is my snippet. I assumed setting the picturebox image to something else would fix the problem. I does not. Looks like something is still holding its finger on the file.

Code:
Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Remark the line below out and there is no violation.
PictureBox1.Image = Image.FromFile("C:Tom.bmp")
End Sub

Interface And Graphics :: Handle Varying Currency Values In Maskedtextbox

Mar 4, 2009

I am working on a Windows application written in VB with Visual Studio 2005. I have a number of fields where the user needs to enter currency amounts. I am using a MaskedTextBox with the following currency mask. msktxtAssessedVal.Mask = "$ #######.99"

The problem that I am having is that when the users type in the value, the cursor always starts at the leftmost position and appears to force as many digits as the mask. The typical data values can vary anywhere between 9,999,999.99 and 20,000.00. If the users do NOT have a value that has 7 digits left of the decimal point, they need to move the cursor to the correct position before they start typing in the value. These users are used to quickly typing in their data, then tabbing to the next field so the current behavior is not acceptable. We previously used a ComponentOne MaskedTextbox, however, their controls now are no longer free and the boss will not pay!!!

Does anyone know if there is a way for the maskedtextbox or any text control to detect where the user types the decimal and format the data accordningly?

Interface And Graphics :: Dialog In Center Of Calling Form

Jun 17, 2009

I've got a question and i think its very simpel but i don't get it.

I've got 1 form that is a MdiContrainer for other forms that i'm opening.

(lets say: the main program)

In the main program, i'm opening a form with a datagrid in it (configuration form). If i click on one of the data cels I'm calling a otherform as a dialog to edit some of the value's from the data cel thats just clicked.

But the problem is, when showing this form as a dialog, with the property startposition: Centerparent it displays it as in the center of the main program and not from the calling form. How can you correct this? Because i'want the dialog in center of the calling screeen.

dialog.parent = me: wont work

see attachment for the program.

Interface And Graphics :: DataGridViewComboBoxColumn Change To Automatically Update Datagridview?

When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen?

Interface And Graphics :: Lots Of Data To Handle - Locate A Tile In The Map When It Is Clicked?

Jan 31, 2011

My tile-based map editor project. So far, it works really awesome. Here, look at a picture: [URL] And the screenshot is outdated: Now I got the Pencil, Rectangle and FloodFill tools too!, the tilesets are from that popular (well, not so popular) game engine called RPGMaker.

Currently, this is how the map is structured:
One ArrayList represents the X coordinates.
One ArrayList in each X represents the Y coordinates.
One ArrayList in each X,Y represents the tile.
The tile is an ArrayList containing three elements:
The Image name (Tileset01 in the screenshot), the X coordinate in the image, and the Y coordinate in the image. Those coordinates are from the TILESET01 image, not map.

Getting the idea?
How do you locate a tile in the map when it is clicked?
First I get the cursor's position on the map picturebox, then convert it to a multiple of 32 (the tiles are 32x32, yes), divide the position X and Y by 32. The results are the indexes I need to get to the tile I clicked.

That method works just fine for me.

When the map picturebox invalidates and needs painting... When that happens, I iterate through each X and Y arrayList. When I get the arrayList that represents the tile, I use it to draw on the map.

For example:
Iterating X arrayList.... step 8......
Iterating Y arrayList..... step 3.......
Found arrayList with three elemetns: ("Tileset01",32,96)
Draw image on the map picturebox, source is "Tileset01" on rectangle (32,96,32,32)... draw it on map picturebox's point (8 * 32) and (3 * 32)

And so on.

Now you understand how I am working with my map editor, how I am locating clicked tiles, and how I am drawing it. Everything goes fine, except for one problem: At some point, the user might want to make a 500x500 map.

That means, an arrayList with 500 elements representing the X tiles. Then an arrayList with 500 elements for each X tile, representing the Y tiles. Then an arrayList in each X,Y pair.

Then multiply that result by 5, because there will be 5 drawing layers. How am I supposed to handle such huge maps?! My app explodes when I set the map dimensions to 500x500! 500x500 is the max setting allowed in my app. I also know that 500x500 map editors are possible, because I have seen others before. With great performance.

Automatically Recognize And Handle Changes Of An Item In A "System.Collections.ObjectModel.Collection"

Feb 4, 2011

I wanted to create a custom control with a custom Item-Collection in it.(Similar to the ListView Items, but with other properties)I wrote a Class that holds properties of a single Item data (ClassItemData) and another class that "Inherits System.Collections.ObjectModel.Collection(Of ClassItemData)". The Collection class contains a public event (ItemCollectionChanged) which is raised when "ClearItems", "InsertItem", "RemoveItem" or "SetItem" is called. (I used "Overrides" on all these functions and added the Raise Event to them.) The event is handled in the custom control itself and causes the control to refresh/repaint itself. The collection class contains also "Default Public Overloads ReadOnly Property Item(ByVal index As Int32) As ClassItemData" which returns the Item at the speciefic index.

The control refreshes itself when I place the control on a form and use code like: ControlName.Items.Add("TestItem") Unfortunately the control does not refresh itself when I use: ControlName.Items.Item(0).Visible = False The value of the Item itself has changed after this, but the control does know about the changes and does not refresh itself. If I do a manual repaint/refresh of the control, it looks all fine, but it does not work automatically. Does anyone know, what I have to add, so I can handle an event or something in the control when a property in the ItemData class has changed? How do I recognize changes in existing items and raise an event in the custom event?

User Control Accessing A Form Within The Project?

May 1, 2010

I have a "windows form" user control--that is, not on a web page etc. This user control has a form within the user control project. However, code from within the user control can't 'see' the form even though it is a public class---I don't understand why this is the case.

So how can I access the controls (a couple of radio buttons) on the form from code within the user control? I tried creating public properties on the form to return the state of the radiobuttons, but this still doesn't work. I get a "Reference to a non-shared member requires an object reference." error

Should I not be able to see the form since it is a public class?

ASP.net User Data Getting Crosses Between Users Accessing Objects?

Jan 4, 2010

I've got a website and we just had a huge jump in traffic. Now all of the sudden we're getting sql parameter errors left and right. We switched to a new sql server a few weeks ago and everything has been fine but the added traffic seems to be breaking us.I have a data access class that is called when each user trys to logon. It runs through several tasks before finally updating the users last login date and forwarding them to the administration section.

What I'm seeing from the trace logs suggests that when I'm logging in the first several tasks are using my data (lets say user=birk pass=word). But at some point the accessor class starts sending over the data from someone else who's trying to login (lets say user=abcxyz).Every connection we make to the server is closed when we're finished with it. I'm nulling out all of the accessor objects when I'm finished with them. But somehow different user data from different sessions are making their way into other peoples instances of the object.

I'm not using session/application/cache/viewstate to store the objects so I'm not really seeing how they could edit eachother... Its just really weird and I'm not sure how to even go about researching the problem.This is roughly the accessor class... I trimmed out some of the parts that weren't reliant to the issue
