[VS2005] SafeArrayTypeMismatchException - Passing Two Structures Arrays And Other Single Values

Sep 29, 2008

I have written a ActiveX DLL in VB 6 which is like -

[Code]...

When I do this everything works fine and I am able to pass value to dll. I am passing two structures arrays and other single values like int and double etc. So far so good. But when I insert this code in another application (created in same vb.net 2005) where I actually intent it to use then i get the following error -

System.Runtime.InteropServices.SafeArrayTypeMismatchException
Specified array was not of the expected type.

I am puzzled as to why is this happening. I checked basic settings and they are same. In short the code works if i create a new project and go on but does not work and gives error if I insert in an existing application's code where i wanna use. To test I created a dll without passing structure arrays and then it worked in that application.

Passing Arrays Through Fortran Dll From App Turning To Single Element Arrays?

Feb 2, 2010

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working

(2005) Arrays Of Structures Within Structures?

Jan 20, 2009

I 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.

Structures And Arrays Of Structures?

Jun 2, 2010

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 ".

Using Arrays In/with Structures?

May 24, 2009

I'm currently doing this project where i have to create a program that let's the administrator manage students (and their tests.) I have decided to use Random Access file in this project.because structures will need fixed lengths...i don't know how will i search through the students (a function of the program) when each student structure has a different length because of the number of tests they've done.* I have created a variable in the aStudent structure so that i can know the number of tests a student has done...but don't know how to use it.

Creating A Database Using Structures And Arrays?

Nov 15, 2011

I want to create a relational database in VB2010 and I am attempting to accomplish this goal by creating a structure of records to be stored in a Random Access File.For each record, I want to organize each fixed-length record so that 4-integer sets of data are stored into a a multi-dimensional array.But when I try to write the code below at the module level, I get an error.

Structure PictureDat
'len= needed for Open
of Random Access File [code].....

Since I want to read/write/save the data in this structure to a Random Access File with a fixed record length size, I need to exactly specify the size of the record...which is, of course, determined by the array's dimensions.If I could accomplish this strategy, then I could search this random access file for a match of search criteria consisting of 4-integers with any of the 4-integer sets of data in each record and thus find, edit, delete and search records...therby retrieve information from my database.

Is my program design inefficient? Is there a better way to handle perhaps hundreds of thousands of records? The IDE keeps telling me that I am using a deprecated method of file I/O when I use FileOpen(), FileGet(),FilePut() and should be using MyFile.I am entirely comfortable with my time-tested method of data storage that ensures the security of disk storage while exposing only one record at a time to the PC's volatile RAM, thereby not allowing all my data exposed to possible memory corruption on a PC left on for hours, which would be the case if I loaded the whole file as a monster- sized string or stream. Also, these older file access methods allows my code to run on PC's with modest amounts of memory.

Sharing Structures Of Arrays In Multiple MDIchilds

Nov 10, 2010

I have the following code... in an MDI application. [code] Various lines of code which put data into the Myinstance and then save the instance into the ArrayList.I have buttons which run procedures and functions in the formchild and also in the Class1. I need it so you can jump between formchild instances, and when you do so and click a button on that form, it will run the Class1 code but using the data in the arraylist and myinstance that was set previously by the selected formchild. Then if you switch to another child it uses data from this form. Can this be done by declaring the arraylist with more dimensions and then refer to the records with the index of the selected form instance, e.g.Selected Child is index(3)

Sharing Structures Of Arrays In Multiple MDIchilds?

Nov 6, 2010

I have created an MDIparent form and a MDIchild. There is a button on the parent which makes multiple 'clones' of the child form, each time its clicked.I also want (maybe with a module) a set of variables, and array of a structure but these are available to each copy of the child, but each copy's variables, arraylist etc contain its own data?Therefore if you select child1 the variables and array will have different data to child2, child3...etc...

Passing Structures As Arguments For A Fortran DLL?

Sep 11, 2010

I could pass a User Defined Type data structure to a Fortran DLL, that contained Short Integers, Singles (real variables) and a series of Fixed Arrays, both short integers and real variables.I am upgrading my VB6 app to Visual Studio 2008 - VB, and I want to keep the same data structures as they are used in about 300,000 lines of code.I modified the Data Structure as follows below, making sure it is of Explicit Layout, since I want the position of all variables to be the same both in VS 2008 and Fortran.Two problems arise:

1) if the LayoutKind is Explicit, such as in the example below (only part of the data structue is shown, where "..." indicate part of omitted data structure members), whenever I try to run my app, I get the following exception message, which indicates that the VBFixedArray declared at Offset 154 is in conflict with some other object, unnamed by the exception handler.

Message="Could not load type 'MyApp.SomeStruct' from assembly 'MyApp, Version=1.32.3906.33480, Culture=neutral, PublicKeyToken=null' because it contains an object field at offset 154 that is incorrectly aligned or overlapped by a non-object field."

Source="MyApp"
TypeName="MyApp.SomeStruct"
StackTrace:[code]....

2) if the LayoutKind is Sequential, the app will start, all the data preceding the VBFixedArrays is passed to the Fortran Dll without problem; everything that follows the VBFixedArray is garbled and unusable. To check this, I have made a Fortran subroutine in the Dll to which I pass both the Data Structure and a vector; in the Fortran subroutine, all the elements of the data structure are equivalenced to individual positions in the vector; upon return from the Fortran subroutine, I compare the elements of the data structure and those of the vector.

The problem here is that the Data Structure contains some 1300 names, and is used extensively in the application, as it is the way to pass elegantly a lot of data pertaining to a mathematical model with only one adress when accessing the Fortran Dll, in which the computing engine lies.

VS 2008 Passing Structures Between Modules?

Apr 25, 2010

i have a main module called "main", within the module i have declared 2 other modules "Interfacing" and "Espec", within these 2 submodules they both have a structure called "coord" which is identical. The problem is that when i have defined a function in one module with "coord" as type and try to assign a value in the other module with coord type i get error message "Value of type Main.Interfacing.Coord cannot be converted to Main.Espec.Coord", so basically how could i pass that structure?

FileStream Delineator - Delineating Data Structures Chained In A Single File

Jul 31, 2009

I'm working on something whereby I write and read alot of data to disk directly as bytes. But I can't figure out a foolproof way of delineating data structures chained in a single file. A null byte obviously wouldn't cut it, because that could occur within the data structures themselves. Theoretically, any pattern of bytes can potentially occur within a data structure. Does anyone have any ideas for a byte pattern that I could use as a flag for my streamreader? Anything reasonably short, since it's going to be pretty complex, streaming through each file twice, once byte by byte to find the flags and again to split the stream.

I'm trying to pass an array from a 2D Array to a function that takes a 1D array, but each time I do I get the error Number of indices is less than the number of dimensions of the indexed array.. I know using a structure would solve the problem, but unfortunately the assignment is to use a 2D Array instead of a structure. I've declared the 2D array as such:

Const MAX_ARR_SIZE = 63
Public HouseholdCollection(MAX_ARR_SIZE, 2) As UInteger
Const IDENTIFICATION_CODE = 0

VB, Passing And Returning Arrays From Functions?

Nov 27, 2009

I ran into an error when trying to do this:

Code: ChartBuffer = GetCurrentChart(ChartBuffer) The error says Conversion from type 'Integer()' to type 'Integer' is not valid.

Apparently I have some type casting issues, the problem is I'm not trying to cast any types at all. I'm trying to set one array chartbuffer equal to the array returned from GetCurrentChart.

[Code]...

In the constructor of this class I am trying to set the buffer equal to the loaded chart because if I try to write information to a buffer that isn't already initialized, and then save it, it will overwrite stuff that might already be saved in the file as 0's or something, and I don't want it to do that. To prevent this from happening I'm simply going to initialize the buffer in the constructor by setting it equal to the loaded chart. Finally after that is all done I can write new information to the buffer and save it to the file without writing a mostly empty buffer (full of zero's) to the chart that is saved with information in it already.

Passing Command Line Arguments To Already Running Single Instance App

Jan 19, 2010

I have a single instance database app that emails out notifications. I would like to add a link in the emails that when clicked would open up the app and go to the section of the program that its supposed to go to. I implemented my own URL protocol so that links starting with my codewords get passed to my EXE. So far so good. I then parse the URL and pull the keyword and identifier out to open that section of the program. So if a user clicks a link like this:

MyApp:LoadCompany?ID=323

My application will start, it will grab the arguments (LoadCompany?ID=323), pass this to my load company routine and then load up company ID 323. Works great.

Now the issue is if the program is already open I still want the links to work but since it's a single instance app it just closes the second app. How can I add something ot the app to watch for this or receive a message from the second app? I know I will need to check status of what I'm doing and make sure things are saved, check security, etc but I can get all that done easily enough. I've found some examples online but none really did what I wanted them to.

Adding Values Of Two Arrays?

Below is the code, as I said everything seems to be working fine aside from adding the two array values and then displaying them as currency.

Do Arrays Take Up Space Even Without Values In Them In .net

Sep 28, 2011

I have a program in VB.net that uses a 3D array:

Private gridList(10, 900, 900) As GridElement

Now, I just used a Memory Profiler on it (because my application is having some major leak issues or something) and apparently, this array (containing at the moment of testing 0-30 elements at one time) is using 94% of the memory currently in use by my application. Even when it is empty it takes up huge amounts of memory.

My only assumption is that even empty arrays take up space! This puts a major blow into my plans!

My Question:

Is there any alternative to this that allows me to still have the same abilities to map i.g. I've been using it like this:

Dim cGE as GridElement = gridList(3, 5, 7)

but doesn't hog up so much memory for things that aren't using memory?
