Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.

I have developed a form for Windows VB.Net that uses a number of text boxes that are indidivually bound to separate columns in a database. When one of the textboxes (let's call it XYZ.Text) is bound to the database, it prevents the data from any of the other bound text boxes to enter the database. When the binding for this one text box (XYZ.Text) is removed, then all the other text boxes work fine.

Description of problem: I have a simple form with a usercontrol on it. There is a drop down box with a list of departments in it and a button, this is all in the usercontrol. I pick a department then press the button to view the employees in a listview for the department picked. All worked fine until I moved the code for drop down and button into the usercontrol from the form.
The data is taken from oracle database express 10G edition and I am using a cursor package (CP) and I pass parameters from the code to the oracle procedure within the CP. One of these parameters is the selected department from the drop down list (which I have picked) and my code does not seem to be picking up this parameter, it keps saying that the bold bit of code below is nothing:
myCmd.Parameters.Add(New OracleParameter("n_dept", OracleDbType.Varchar2)).Value = usr1.cmbDepartments.SelectedItem
Everything else seems to be fine. Because it is not picking up the selected item then the dr.read (no data by the looks of it) is false and it just falls out without populating any employees for that dept in the listview.
Does anyone care to take a stab at suggesting what might be wrong? Why won't it pick up the selected item in the user control I have just picked it in?

View 6 RepliesStarting from a table like this:
| Code | Year |
---------------
| A01 | 2001 |
| A01 | 2002 |
| B01 | 2002 |
| C01 | 2003 |
I have to arrive to this:
| Code | Year |
---------------
| A01 | 2001 |
| B01 | 2002 |
| C01 | 2003 |
I have to group the first column (Code) and from the second (Year) I have to get the data 'less common as possible' compared to all the other records. I try to explain this with the example: for the code 'A01' I have 2 years: '2001' and '2002'. I have to take '2001' because it's the one that not recurs in the other records. In the case that there aren't available values 'Year' that not recurs in the other records, it's good to take whatever value.
The data are in the form of array in memory and to interact with them I'm useng some LINQ queries.
I'm trying to just iterate through this xml and grab all of its data and add it to my collection(_personOC). Right now it's not working. How can I do this without having to specify the id? All I did was make a dataset with a person table and saved it as a xml.

so this is the problem our professor gave us. the user given a chance to log-in correctly 3 times, assuming that a user log-in his/her password incorrectly there will be a loop, counting its no. of attempts. and if it exceeds to 3, there will be a msgbox assuming "you log-in incorrectly 3 times" etc. here in my code it counts but the msgbox ("try again") shows 3 times.

View 1 RepliesI am writing my first MVC application, and struggling with how best to pass data from my controllers to my views. I have a very simple XML document structured like this. (Yes, this is Magic: The Gathering data)

<block>Shards of Alara</block>
<cards>145</cards>

But I get an Object Block or With Block error when trying to access SelectSingleNode("block") on the second "set" node, since that node doesn't have a "block" node.I also have a feeling that the way I'm approaching the view is all wrong. Is there a better way to get this simple XML data into the view so I can work with it?
So another first timer question.I have user entered data from a form that gets put into separate strings. On another form i want this data to populate a Tree view when the user presses a button "Add data". There will be only one stage of parents and child. oParent and oChild. The oParent string will only have like 5 items but the oChild will have like 30 and these will be repeated for each oParent. Not sure how populate this, i cam guessing with some sort of For Each i in oParent, add i or whatever, but not sure of the syntax.

View 4 RepliesI've ported a page from classic ASP to ASP.net. Part of what happens in this page is that a collection of custom types is generated and then displayed via Response.Write() commands. I'd like to get the business logic separated out into a code behind file (and maybe move this all into a user control), but I can't seem to figure out how I'd actually display the collection once it's been generated. I want to specify a master page here, too, so the code can't stay inline. Here's a very stripped down version of the current code:

How do I get my form to display a simple digital counter? I have a "record" function on my program:
Private Sub Button13_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("record recsound", "", 0, 0)
End Sub
I want to have a simple digital counter display while the program is recording. That way the user can know how long the audio is so far while recording. Then when the user is done recording, the timer will stop.
I would like to know how I can read a number from a text file then multiply that figure by one and write that back to the original text file, I'm trying to make a counter to keep track of how many times my forms are executed. The information will then be used to determine the success of my apps with in our company.
View 1 RepliesWhile a fairly simple form it has had its problems. The latest is an error message (see below) that I do not understand and hence cannot correct. I have looked at the other postings, but did not see one that would apply.
CODE:
I'm creating a windows forms program and have recently noticed a large amount of memory slowly being eaten by the application. I went through my program and tried to tie up as many loose ends as I could in relation to object creation but noticed that the program would still keep memory for every form loaded until it eventually crashed.
I decided to make a simple test program which sole purpose is to pop-up a new form with a few controls, wait for 200 milliseconds, then close the form and repeat the process 30 times every time I hit a button. I found it caused the same behavior, even with the only new object creation being that of the form. So, I decided to manually invoke the garbage collector in a subroutine which handles the formclosed event. During tests I would get some memory back occasionally, but not enough to make a difference in the long run. So I start setting the form variable to nothing before I called GC.collect(). The program will initially eat a few 1000K of memory before leveling off and using only 20-40K for every 30 forms created.
Now what I'm wondering is, what is the point of an automated garbage collection system if it requires constant manual evocation and explicit dereferencing of all new objects to be effective? Have I completely lost grasp on the scope of VB.Net forms and it simply never marks forms as available memory to be cleared?I would have thought object memory references created within a form would be marked as usable when the form's close or dispose routine is called and no references to objects created within the form exist anywhere outside the closed form.

I am wanting to make a collection of form instances.I was wondering if the arrayList is a list of pointers (or references) to items added or if a new instance of an object is placed when using the add method.
i.e. if I had: Public Shared forms as Arraylist = new Arraylist Then if I called forms.add me from an instance of a form would it create a pointer or reference to the instance or generate a whole new one?
