Crystal Report And Code Optimization?
Jul 24, 2009Ok, the error I'm getting is "Load Report Failed" and it happens when I need to load a large number of crystal ReportDocument objects. I've searched on this, and there is a property in the registry that you can change to -1 and it allows to load more, however I'm still getting the error, just after I get about twice as many documents loaded.
The report is basically a one page document (for each client in the database with an interest charge). It displays the amount of interest charged, and other information pertaining to the charge. These documents are basically printed out and mailed to the client.
I created a "Print Preview" screen which has a CrystalReportViewer object, and an ArrayList property. The ArrayList property has an array of all reports, and there are next and back buttons to browse through each report. Once they are satisfied, they will print them all out, and I can dispose of the objects.
The solution for this, from everywhere I've seen, is to "Dispose the object after you are done with it". My problem is that I can't dispose it until they are finished with the print preview screen.
Is there a better way to go about this that won't require too much time to code (we are already over the deadline on this project) or a simple solution to get past the ReportDocument limit? Right now it is erroring on report 150., There are 180 records (as of today) that need to be loaded.

VS 2010 Code Optimization: Array Initialization?
Jan 20, 2011I'm wondering if you know if there is a better way to write this code in order to speed it up. It has several blocks of if statements filling arrays, like this:
row0: If x < b(1, 1) Then a1(i, j + 1) = 0
If x > b(1, 1) And x < b(1, 2) Then a1(i, j + 1) = 30
If x > b(1, 2) And x < b(1, 3) Then a1(i, j + 1) = 60

Forms :: Optimize Code And Lower CPU Usage?
May 14, 2009When my form first loads, it runs at about 30k CPU, but after about 10 minutes of use, it goes up to (and stays at) about 70k CPU.
What ways can i optimize my code to allow the CPU usage to stay low, or how can i lower it during the running of the program.
My most concerned areas of the CPU are:
1. I have a web browser, and when a user types in a url and presses go or enter, the CPU jumps about 4k:
Private Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Go.Click
WebBrowser1.Navigate(OldURL.Text)
[Code]....
The second worry is when i open other forms, it boosts the CPU up aswell. the only code for this is:
Form.Show()
Optimize The Code For Copying Data From One Dataset To Another?
Oct 6, 2009this is in reference to my main post here update mdb with data from different tables in dataseti have two tables in a dataset called dsSource. dsSource.Tables(0) has the following columns: ,,,,,,,code,art,sizerng1,sizerng2,sizerng3,etc...... dsSource.Tables(1) has the following columns: ,,,,,,,code,art,size1,size2,size3,etc...... the conditions here are: 1) to look for "1" in columns sizerng1, sizerng2, etc. of dsSource.Tables(0) 2) match code and art on both tables finally if both conditions are valid then the size values in columns size1, size2, etc. will be assigned to columns in sizerng1, sizerng2, etc. my main concern here is i have to loop through all rows in both tables which takes a long time, so is there a better way to do this than the code i have below?.
'***put the sizes from weights to traps file
row1 = 0
For Each dr As DataRow In dsSource.Tables(0).Rows

Code Written In C# - Conversion Of Csharp To VS2005
Jul 3, 2009I have some code that was written in C# and am attempting to convert it to VB.Net, for the most part things have gone well but I am running into an issue that I am not sure how to handle. The project has several classes and a few namespaces defined. The issue is [or seems to be] related to the namespace usage.
In the C# code of one class I have
Code:
namespace GdiPlusLib
In another class I have
Code:
using GdiPlusLib;
When translated to VB I have in the first class above
Code:
Namespace GdiPlusLib
and the following in the other class from above.
Code:
Imports GdiPlusLib
I get the following warning message on the imports line
Namespace or type specified in the Imports 'GdiPlusLib' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases. There is another instance with a different namespace that gives the same warning and I get 11 errors all of which would seem to be related to the two warnings.
Incorporate The Code Written In The Batch File ?

End Sub
Is it possible to incorporate the code written in the batch file so that I won't have to call it like the one above?

.net - Optimization With Visual Studio Or A Logic Bug?
Feb 3, 2011I have an small physics toy application I am developing. It works fine except the particles will not push each other away, only pull towards, I debugged that sub going through it command by command and realised the value 'H' would not change, what ever it was set to during the first pass through the sub is what it kept, the only way to change this value is to manually set it i.e 'h = 1'. Once the calculation is redone on the 'H' value it resets to what it was previously, even though the x1,y1,x2,y2 are all different, thus meaning H should be different.
I think it is me that has made a mathematical mistake somewhere, but I cannot see where it is. I need a fresh pair of eyes to look over my work. Please let me know if you find anything.

[2005] DataGridView Scrolling Optimization

Will The Compiler Optimize This
Mar 8, 2012Consider this
bar = 1
foo = <1 or 2, depending on previous code>
if foo=1
while bar <= 5

What I want to know is, is the compiler smart enough to optimize away the (apparently) repeated tests for "foo = 1" since foo is not modified in the body of the loop?If so, I might use the second construct since it is semantically equivalent (I think!), takes less code and reduces indentation levels.
