Picturebox Paint Doesn't Display Correctly When Load From A Catalog
Jul 9, 2010
I am building a form that will load individual items(from individual files) or a catalog of items(from a list of items). I then click the item I want to use to select it. Everything works correctly, when I click an item it selects the correct stitch. The only problem is, it doesn't display correctly when I load from a catalog. I can open individual items and it works fine. When I load a catalog it doesn't display the images correctly.

I have a VB 2008 application with multiple DataPicker fields. The data is binded to SQL database. On the form load I set the checkBox for each date to false if there is no date in the field. Noticed that if I make changes to some dates for record 1 in the table, save it and scroll to the next record - I see the date that I just changed for record 1 - also on records 2 and 3. Why is it happening? I don't have that problem if I use text fields to display the dates. I had encountered the same problem with different project and just switched to text boxes. With this new project?

In trying to test some graphic features, I am trying to get them to display on load so button doesn't have to be pressed. I used the following code as suggested from forum. Message boxes run but ellipses aren't displayed until button is clicked which is what I am trying to avoid!
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

correct way to draw rectangles onto a picturebox, and also to explain the paint event more clearly.Basically I have an application where a picturebox contains an image, this image is a small computer monitor as such:
The idea of this part of my application is that the user can draw small window size rectangles which represent windows later on. I have already used some excellent code on this forum to be able to draw the rectangles on the picturebox (As pictured above), the rectangle outline is drawn from MouseDown and MouseUp respectivley.
The problem I am encountering is with the 'repainting' of this rectangle. I have included code to repaint the rectangle in the Paint event of the picturebox. This works when you move the picturebox 'off screen' and bring it back. However when the form is re-sized or other various things occur the rectangle is not re-drawn? even though the picturebox 'appears' to be clean and always there!
My code is below, it is not full and complete, but the few main subs listed should give an indication as to how I am currently creating the rectangle:
Private Sub picboxAdvDisplay_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles picboxAdvDisplay.MouseDown
'Set the flag for Drawing enabled
[code]....
1. What is the CORRECT way to draw a rectangle onto a Picturebox?
2. How do you code so that the rectangle is ALWAYS visible/drawn on a form re-size, minimise, window overlap etc etc.

I am working with a picturebox and i am drawing lines during my paint event. My goal is too draw the lines and export the picturebox.image with the lines i drew out to a Everything seems to be working correctly so far. The code executes. A file is written. But it is always just the original image from the picturebox with no lines on it. I have setup the pictureboxes so i can see exactly where i am in the code when it trys to save. I can also verify that before i click the button that calls the save feature the lines are absolutely drawn in the picturebox.
I seem to remember someone telling me at some point that the lines i draw wih the paint event are not actually a part of the picturebox image but more an overlay on top of it. I think this may be my issue. Hopefully someone can shed some light on this.

I have a UserControl that has a ProgressBar on it. The purpose of the UserControl is to be able to show the progress % on the ProgressBar as text. To do this it uses the MyBase.Paint event. To make it work the ProgressBar is made invisible and the UserControl is 'painted' with an image of the ProgressBar and then the text is painted on top. The UserControl has a Value property that is passed through to the ProgressBar.Value property.
I use this UserControl in two places, on a Splash form (not a standard Splash Screen) and also on the main form of the application. It works on the Splash form but not on the main form - by work I mean that changes to the ProgressBar.Value property cause the ProgressBar to show its progress. The cause appears to be that in the Splash form case the MyBase.Paint event is called as a consequence of calling Me.Refresh in the Set procedure of the UserControl.Value property, in the main form case it isn't,
i.e. Me.Refresh isn't causing MyBase.Paint to run.
The main form has two BackgroundWorker components. The first gets called (RunWorkerAsync) from Form_Load after the Splash form has been shown. The BackgroundWorker.ProgressChanged event updates the Value property of the UserControl and it works exactly as intended. The second gets called as a result of a user starting an operation and again the BackgroundWorker.ProgressChanged event updates the Value property of the UserControl but MyBase.Paint doesn't run so the ProgressBar remains resolutely static.
Any ideas why it won't respond to Me.Refresh in one case but does in the other? Happy to make any of the code avaialble but didn't want to fllod the first post with reams of it. Here's what I think are the most relevant code sections. First the UserControl

I am making this program for a school assignment but it has errors when calculating
Private Sub frmReceipt_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'When this form is loaded, assign the date to the date label & start the timer
lblDate.Text = Date.Now
[CODE]...
So if counter finishes, execute the following code
If counter > 4 And km >= 1 And kmcashset = 0 Then 'If there is still kms to calculate 'And kmcashset = 0
kmcashholder = kmcash
km = km / 5
[CODE]...
And if I add counter = 0 and km = 0 at the end of that "If counter > 4 And km >= 1 And kmcashset = 0" Then it doesn't calculate anything correctly. I supply it with 9 for Distance and it returns 4 for excessdistance which is correct but returns 7 for excessdistancecharge when it should be 4! When I supply 23 for Distance it returns 18 for excessdistance and 11 for excess distance charge which is correct. (???)
Excessweightcharge calculates correctly.
I think it may be the way I'm implementing it, through the use of AND or maybe it's because it's in timer tick?
-Minimum charge of $5 which covers 10 kgs for the first 5 kms only
-Each kg over 10 kgs incurs a charge of $0.50
-Distances over 5 kms incur an additional charge of $1 per km up to 10 kms
-For deliveries over 10 kms, the extra distance should be rounded up to the nearest 5 kms and charged at $2 for each extra 5 km block.
EXAMPLE 1:
Packet weighing 9kms travelling 9 kms
Standard charge for first 5 kms ($5.00)
Weight less than 10 kgs so no extra weight charge
Extra distance charge 9 - 5 kms = 4kms x $1 = ($4)
Total delivery charge = $5 plus $4 = $9
[But my program returns 7 for excess distance charge]
EXAMPLE 2:
Packet weighing 33kgs travelling 23 kms
Standard charge for the first 5 kms ($5)
Excess weight 33 - 10 kgs = 23kgs x $0.50 ($11.50)
Extra distance (23 - 5kms = 18kms):
18kms ( 5 to 10 kms at $1/km) = ($5)
13kms (18-5)/5 = 3 (rounded up) x $2.00 = ($6)
$5 + $6 = $11
Total delivery charge = $5 plus $11.50 plus $11 = $27.50

I am using a PictureBox to display images. I have SizeMode set to StretchImage. While this does indeed show the whole image, it is of coure stretched. Is there a way to prepare the image to be displayed so it will fit correctly in the PictureBox? I just want it displayed without distortion and within the box.

Create a generic label method:
Public Function buildBasicLabel(ByVal labelName As Label, ByVal text As String, ByVal font As Font, ByVal align As Integer)
Dim tmpLabel
[Code]....
For some reason, the label is not lining up with the others once I span it. I'm trying to span it to get all the text to show but once I do, it starts pushing it over. I don't see anywhere where I restrict the size so that shouldn't be the issue.
I tried doing all this in the design and it works just fine. Mimicking the designer code doesn't seem to fix it either unless I'm doing something seriously wrong...
Posting images for clarity. NOTE: The borders are just to show the label alignment and the text should read "Flat-Footed AC"
IMAGE 1: Spanning 1 column (doesn't show all text)
IMAGE 2: Spanning 3 columns (still doesn't show text and you can see it's starting to dis-align)
IMAGE 3: Spanning 6 columns (Still doesn't show text and greatly dis-aligned. It should at least show all the text)

Running into a situation when user searches for orders of customer for past 4 years. As the DB query takes a long time, I want to show a pop up box just stating 'please wait. quering for results'. so when they start their search I want to show the message box until the results are obtainned and at that point I want to close the message box.My current way, I know is incorrect as the pop up box locks up and states (not responding).Would using a background worker be an over kill, or should I go with a progress bar?

I'm using the following code to read in a highscores file with the score written first and the player's name written to the next line, and then display the top 3 scores or fewer if there aren't 3 scores written to the file. A highscores display should have the scores sorted with the highest first so that's what this program tries to implement.
Array.sort() isn't doing a damn thing. In fact, the program's not even reversing the arrays like it should either. I've tested array.sort() this way with the names and scores arrays given explicitly and it works fine. I thought maybe it was still reading the data as string even though it's declared otherwise but it rounds off decimals when I change the array type to Integer so I'm pretty sure it's not that.
I have no idea why reading the data in from a file changes how it's sorted. My teacher didn't understand what was going on either. Does anyone know what's going on here?
