I have a structure that I want to copy, but I don't want to have to copy it item by item if I don't have to. Is there a way to do this? EX:
[Code]...
I remember in Fortran and C there were statements like Common, Union, etc. that would equate two objects or arrays or words or arrays. Does VB have anything like this?
The scenario is I would like to be able reference two similar 3rd party assemblies (e.g. assem1 and assem2) which both define a type with the same fully qualified name (e.g. Example.MyType). Is there any way to distinguish between these and refernce them seperately? I believe the answer is no but confirmation or correction would be handy. Edit: Answered for C# 2.0 and higher below but need an answer in VB.Net 1.1

Basically I have a form with Five textboxes and what I want to do is to click a 'Submit' button and copy not only the text from all 5 textboxes but the name of the textbox or a label.
Sample:
Names / TextBoxes
Box1: Text1
Box2: Text2
Box3: Text3
Box4: Text4
Box5: Text5
And when you click submit you would get the text in that format when you paste it in a separate textbox.Is it possible and how would I go about doing that? I know I can copy multiple textboxes but I want to retain the label or title along with the filled in text.
I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.
View 4 RepliesI have a structure called 'Scheme' and in my program I want (ideally) an ArrayList of 'Schemes' (so i can add, remove schemes etc.). However, within the 'Scheme' structure, I want to have an ArrayList of 'Item''Item' is another structure. Are there any solutions out there for iterating through these arrays quite easily?
How can I easily add multiple Items to a Scheme and mutliple Schemes to my Scheme array. Code is below. When I try to add Items to a Scheme, I get the 'Object not set to a reference of an object, try the 'New' keyword', but you cannot declare 'New' keywork within a structure.

I read in the Book "Mastering Microsoft Visual Basic 2008" about "User-Defined data types".The example given is creating a Structure as follows.I wanted to check that so I wrote all the code given; I used a TextBox and a Button for this.(I didn't include the "CheckDate" here; that is in the book)
Structure CheckRecord
Dim CheckNumber As Integer
[code]....
The problem is this does work.What I get is "00000". and I found out that the "Checks(4)" Array does hold any value ie: on keeping the cursor over that, it shows "CheckAmount 0.0, CheckNumber 0 , CheckPaidTo Nothing ".
I'm attempting to create a list of structures that contains a list of structures. I can't seem to figure out how to properly allocate the object for the inner list of structures. I expect the outer list of structures to have a couple thousand entries and the inner list of structures to be fairly small at 2 to 10. Both lists will grow over time but the number of elements within the inner list will be constant for an instance of the outer list. Meaning, if an instance of the outer list has 2000 entries each of those will have the same number of elements on the inner list, say 4 entries.
Here is a simplified code fragment. This fragment makes no attempt to create the instance of the inner list "StructBlist" since I can't figure out where to put it. Tried "New List(Of StructB)" in the declaration as well as "Alist(0).StructBlist = New List(Of StructB)" but neither works.

View 8 RepliesI am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

View 1 RepliesMost of my check boxes look like these (on the left of the picture) (ignore the checked check box in the upper left corner , I am not talking about tat one) :However , ONLY on tab 2 the check boxes look differently in both cases the check boxes are Disabled , but they don't look the same . Why is that ? I even tried copying the check boxes from tab 3 to tab 2 but to my surprise they once again looked differently ! This only happens on tab 2 . How is this possible ?
View 20 RepliesWhat is the difference in the two blocks of code below? I expected them to return the same result, but they don't.
In the case where xml.@Type = "null", I want PatientMetricTypeID (a nullable Integer) to end up being Nothing.
Block #1: If()
In this case, it ends up as 0. It looks like Nothing is being treated as an Integer and converted to 0. I can sort of see why this might happen but not fully... I would like to understand exactly how this works, and if there is a workaround.
Dim PatientMetricTypeID As Integer? = If(xml.@Type = "null",
Nothing,
CType([Enum].Parse(GetType(PatientMetricTypes), xml.@Type), Integer))
Block #2: If
In this case, it ends up as Nothing -- expected behavior.

Are these two vb methods identical in function
[Code]....
1. This is probably really easy and I'm just missing it. I have 4 tabs in a controller. The contents in all four tabs will be identical (pictures, text boxes etc.) the end user would then add whatever to it. Whenever I try to copy the contents from tab 1 to any other tabs using ctrl+c and ctrl+v they get all out of alignment. Is there a way to duplicate a tab in the editor so that when flipping through the tabs all the text and pictures are in the exact same spot? I'm going out of mind on something that seams so simple.I don't want to have to write down the location of a couple of hundred controls and then retype them all 3 more times.
2. I can also only select text boxes, labels, and pictures at the same time. It will not let me select text boxes, labels, pictures and drawn lines all at the same time. So I can't really copy and paste everything at the same time I have to do it twice which makes the alignment get even more screwed up.
i have n-Strings. Something about 100. But most of them are identical. How could i remove these multiple string and have only each string one time?

View 2 RepliesI have an application which has a tabcontrol that contains two tabpages. I have a custom made usercontrol docked to fill up each of those tabs. When I resize my main form to the minimum size allowed one tab resizes accordingly while the other seems to overflow the area and a couple ui items slip out of access/view.
One usercontrol was quite literally copied from the other and renamed and fields adjusted. The usercontrol size is the same between the two. Within the usercontrols there is a datagridview and a large panel full of textboxes and they have identical sizes and identical anchoring properties and even the same location coordinates.
I'm struggling to find a difference between the two but I really would like the resize behavior to match between the two usercontrols. I was wondering if anyone would have ideas of other things to check I did not mention here?
I wish to insert a row into an SQL table a multiple number of times. The only field that will change is the Primary key ID which will update automatically.
To enter the INSERT into a loop seems very inefficient (time). The only other way I can find to do this is build up an array of values and do a multiple INSERT but again this seems very inefficient (memory) when the values will all be identical.
Is there a way of saying insert this row a variable number of times?
